Apparently, one of my shrimp is scared out of its exoskeleton whenever it is separated from its mate. Caution Change Content. Scarlet Cleaner shrimp are compatible with most fishes, moray eels, and other Lysmata shrimp species. They are quite vulnerable for a few days once they have shed their exoskeleton, and may hide away until the new shell hardens. One of my shrimp would molt whenever it was moved — whether the larvae were ready to hatch or not; however, if the ripe Cleaner shrimp spawning and Cleaner shrimp spawning mate were both moved to the rearing tank then the premature molting ceased. Yeah I do Love mine. Wish I knew how to post a shriml. Freshwater Saltwater General Tips. These shrimp also act as cleaner shrimp. So far I'm 10 days in and the eyes can be seen starting to develop. They also will not tolerate high nitrate level. The first is to simply wait a couple of hours after lights out with all pumps off and then siphon the fry out and the second is to place a piece of spawnibg where the Hot naked indian woman blow jobs normally lay their eggs and then remove the piece of tile on the night of the hatch.

Breeding Journal DataSheet This first post should be updated regularly to include new information as events take place or changes are made to your system. These are the toughest ornamental shrimp to raise. Larva take somewhere around days to mature. If I can get anything out of it I would feel great if not oh well I had something to do with my time.
MBI: 70 Pnts. Never hurts to try you never know when someone will just happen upon the magic bullet. Thanks Chad, I figure if nothing else works out I will at least get some points for trying. My goal is to breed them by the time I'm out of high-school. If you can breed these to the sellable age, you'll truly be the master.
LOL, I'll have to go for it. I'll post once I notice any eggs in one of the shrimp, it probably will not happen for a week or two so I'll keep everyone posted. You DID! I don't mean to rain on the parade but my single cleaner shrimp has eggs like that all the time.
They need to be fertilized I think to be a real spawn. If I recall they should change color after a certain amount of time or just before hatch which should signal if they are fertile. But the only way to know for sure will be to catch them hatching and being released into the water column. Today the eggs were beginning to get an even lighter green color.
From what I have read the eggs will turn silver before they hatch just like clowns. I'll take some picts tomorrow. So the cleaner shrimp hatched last night, unfortunately I didn't recover any of the napulii since I didn't know they were hatching.
I needed the extra tank for maroon larvae anyway. Ok, well four days ago I noticed that the shrimp had more eggs in its abdomen. Looks like I'm going to have another chance at getting the napualii. So I thought that there would be a hatch today, I was right!!!!!!!!!!!!!! Here are some pictures of the napualii. Very cool Kevin, congrats! Thanks Brett. MBI: 0 Pnts.

Good luck with raising the larvae!
The longer egg carrying cycle followed tank cleanings and water changes. Creating several ledges and overhangs in the rockwork toward the front of the tank will increase your opportunities to view this retiring shrimp. The shrimp has a long larval stage and unusual sexual maturation, initially being male but becoming a functional hermaphrodite once mature. The eggs are fertilized, using the stored sperm, as they are extruded. The shrimp offers cleaning services to passing fish and attracts their attention by lashing its antennae about. During fertilization, two Scarlet Cleaner shrimp couple, joining at midsection with one shrimp assuming a position underneath the other, soon after one shrimp molts.

Cleaner shrimp spawning - Reef Central Online Community
Scarlet Cleaner shrimp are popular invertebrates for marine aquarium hobbyists. When kept in groups they are frequently in view during the day when the hobbyist can admire their bright red and white colors. Also, when kept in groups or pairs, the cleaner shrimp often spawn in the aquarium. My plans to try to rear a few shrimp larvae were delayed for more than a year while I searched for a male Scarlet Cleaner Shrimp. I never found the elusive male: Scarlet Cleaner shrimp are hermaphroditic spawners and all members of a mature group produce eggs which are fertilized by another egg producing member of the group.
In my area, there seem to be more species of shrimp than there are common names. When mentioning cleaner shrimp, readers sometimes think of the large to 7. This article is not about these boxer shrimp. Lysmata grabhami is a Caribbean Lysmata amboinensis look-a-like , whose white stripe runs to the tip of the tail which is not blotched but edged in white. The cleaner shrimp designation is shared by all of these and several other shrimps.
These decapods 10 legs have different attitudes towards members of their own species as well as different reproductive methods. Please do not confuse these when forming pairs or groups as elaborate techniques are required to form pairs of Banded Coral shrimp from non-mated shrimp.
On the other hand, obtaining a spawning pair of Scarlet Cleaner shrimp is quite easy, as any two shrimp are sufficient. Not only can several Scarlet Cleaner shrimp be kept together in harmony in an aquarium, where they make an enchanting display, but they are more often in view when in groups or pairs. All crustacea should be slowly acclimated as they may experience shock if introduced too quickly to a new environment.
It is particularly important that the temperature in the transfer container matches the temperature in the new aquarium. Take the time needed to acclimate them so they can reward you with many years of enjoyment. A few rocks or other hiding places should be provided for the initially timid Scarlet Cleaner shrimp; however, after becoming secure with their new home they overcome their shyness and are frequently in view.
In their natural Indo-Pacific habitat, Scarlet Cleaner shrimp live together in large congregations of up to a hundred shrimp. They feed by cleaning parasites, diseased tissue, and food particles from fishes that visit their stations. In captivity, they perform cleaning services on tankmates. They flag down passing fish patrons by impatiently wielding their antennae and rhythmically swaying their body.
Their tankmates soon tire of the cleaning service and the ravenous shrimp quickly discovers the delights of captive cuisine. They especially relish morsels of crustacea cousins: chopped table shrimp, brine shrimp, and krill.
To say that they are bold feeders is an understatement. They react to feeding time with urgent antics that may convince you that they are in danger of imminent starvation.
The instant the smell of food enters the aquarium they frantically bound towards the aroma. Their large abdominal muscles make them masters at maneuvering; retrieving floating flakes poses no problem to Scarlet Cleaner shrimp. They swim using the synchronized waving of the five pairs of pleopods swimmerets attached to their abdomen. While snaring floating flakes, they appear to be walking beneath the water surface. With the tiny pinchers on their first and second legs, they cram food into their mouth, which is located about one third of the way down the carapace fused shield covering the head and thorax.
They eat so quickly that they appear to be beating on their chest. Their voracious appetite and acute sense of smell entices them to perform scouring duties by cleaning stray food morsels from the aquarium. Once hooked on fast food, they seldom volunteer to clean parasites from tankmates. Scarlet Cleaner shrimp are compatible with most fishes, moray eels, and other Lysmata shrimp species. Predator fishes such as Triggerfish and Lionfish should not be tempted with the opportunity to add Scarlet Cleaner shrimp to their menu.
Scarlet Cleaners do not attack corals. However, they show no restraint and walk on corals with their pointed little legs causing corals to quickly contract at the irritant. Cleaner shrimp may pilfer food from, and pick at, anemones and may not be ideal tankmates for anemones. Variable results, perhaps depending on tank size or food rivalry, are attained when mixing Scarlet Cleaner shrimp with Banded Coral Shrimp.
Some Banded Coral shrimp attack Cleaner Shrimp while others live in harmony together. Against the ferocious claws of a Banded Coral shrimp, the clawless Scarlet Cleaner has no chance. Arrow crabs also have been known to molest cleaner shrimp. Clownfishes and cleaner shrimp are agreeable tankmates in most cases; however, a case can be made for excluding cleaner shrimp from aquariums with breeding clownfish.
I am familiar with a story about a pair of Amphiprion clarkii clownfish which were so annoyed by a cleaner shrimp denying them solitude that one of the clownfish picked up the shrimp and fed it to their anemone. A Maroon clownfish, perhaps mistaking the new crustacea tankmate for dinner, immediately attacked a newly introduced cleaner shrimp. I had a pair of Amphiprion ocellaris clownfish that refused to spawn in the company of a pair of spawning cleaner shrimp.
Perhaps spawning clownfish know that cleaner shrimp pose a threat to clownfish eggs which are unattended at night. During fertilization, two Scarlet Cleaner shrimp couple, joining at midsection with one shrimp assuming a position underneath the other, soon after one shrimp molts.
Apparently, sperm is passed from the hard-shelled shrimp to the recently molted shrimp during this coupling. The recently molted shrimp stores the sperm. Later in the day, the recently molted shrimp extrudes eggs over several hours. The eggs are fertilized, using the stored sperm, as they are extruded.
In about a week the second shrimp molts and the two shrimp again couple. This time, the hard-shelled, egg carrying shrimp, passes sperm to the newly molted shrimp. Within a few hours the newly molted shrimp extrudes eggs and now both shrimp carry fertilized eggs. Thus, Scarlet Cleaner shrimp spawn through hermaphroditic reproduction and all members of a mature group carry eggs.
Sperm can only be transferred to a recently molted shrimp soon after molting, while the shell is still soft, so two couplings are necessary for both shrimp to receive sperm since the two shrimp molt at different times. Hermaphroditic reproduction is common in snails, with each individual outfitted with functioning male and female organs; however, self-fertilization is not common in hermaphroditic spawners so two individuals are needed.
The male Scarlet Cleaner shrimp organ apparently matures sooner than the female organ as one shrimp in a young pair may carry fertile eggs several months prior to the second shrimp commencing to carry eggs.
One shrimp produces four viable egg clutches after separation from a mate. The eggs are fertilized as they are extruded from a stored spermatophore, a packet containing sperm and nutrients that is passed from the male organ of one individual to the female organ of another individual. It is not unusual for a single mature Scarlet Cleaner shrimp to spawn several times soon after being introduced to an aquarium containing no other cleaner shrimp.
After the stored spermatophore is used up, the shrimp spawns one unfertile spawn which disappears within a day or two. Then the shrimp ceases to spawn until fertilized again. Two shrimp were isolated for close observation. All mature Scarlet Cleaner shrimp are similar in size, shape, and color. Each shrimp molted and produced a new clutch of eggs about every 14 days. Occasionally, the molting and egg-carrying cycle extended to 16 days. Infrequently, the cycle exceeded 20 days.
The longer egg carrying cycle followed tank cleanings and water changes. During a particularly rhythmic period, one or the other of the pair had new eggs every Saturday morning. Initially, the eggs are green and densely packed near the body. The adult frequently waves its pleopods and washes water across the eggs to aerate them. The adult picks at the egg mass often and occasionally eats something picked from it.
About midway through the day incubation period, the eggs change from bright green to a light amber color resembling the color of the underside of the adult. As the eggs transition from green to pale amber, the eggs spread out on the pleopods and the eggs, once aligned in four neat columns, appear as an indistinct mound of eggs.
The day of hatching, a few of the eggs change to a dull silver color. The oval-shaped eggs are 1. A compound eye is like a bundle of tiny lenses, each with a fixed focal distance. The compound eyes give crustaceans a bright, but blurred view of the world. For a tiny compound eyed larvae, floating in the water currents must be like living inside of a kaleidoscope with a progression of visual images coming in and out of focus. The ripe-egg carrying cleaner shrimp can be moved to a larval rearing tank soon after a few of the eggs develop the silver color.
In addition to the silver egg color, the refusal of the shrimp to eat in the evening is another clue that the eggs will hatch that night. Feeding the adult shrimp while it is in the rearing tank is not recommended lest the rearing tank water become polluted. The adult positions itself in a good current and the larvae hatch from the open pleopods.
A mild water current in the hatching tank helps the larvae free themselves from the pleopods. Once the larvae are launched on their larval journey, the adult molts. Broken antennae on a recently molted shrimp is a clue to the hobbyist to add an iodine supplement to the aquarium.
The morning after the larvae hatch, the adult should be returned to the main tank. The exoskeleton will still be soft and the coupling of the two shrimp may occasionally be observed within a few minutes of the two being reunited. Careful acclimation is needed each time the adult shrimp is transferred from one tank to another.
One of my shrimp would molt whenever it was moved — whether the larvae were ready to hatch or not; however, if the ripe shrimp and its mate were both moved to the rearing tank then the premature molting ceased. Apparently, one of my shrimp is scared out of its exoskeleton whenever it is separated from its mate. When one of these prematurely abandoned molts, with the eggs still attached, was checked under a microscope it revealed numerous partially hatched eggs and several odd-looking little fellows in the hairs of the pleopods.
There were appendages, hairs, and tiny spikes pointing in all directions. Were they not microscopic sized they would have been frightful creatures.
Nauplii have only three pairs of appendages. The three appendages are the first and second antennae and the mandibles mouth appendages.
