Shrimp/crustaceans.

Lysmata amboinensis-red line-eel cleaner shrimp.

The red line is very hard shrimp to keep for the long term if you don’t understand them, the preferred life style in their environment or you just don’t have good luck!

These shrimp have so many predators its not funny, most tank life may have a go at these defenceless shrimp during a shed, even their partner when the other sheds will at times eat the partner.

If they get scared during a shed they get stuck in the shell as they try drag them selves out through the join between tail and carapace.

The hormones released at and during sheds, are at times like blood in the water to sharks to other tank life and you can guess the possible result

Good quality live rock is the biggest threat to them as to what hitch hikers come with the live rock!

Any clown fish that has a host anemone is a serious threat to a shedding lysmata,they some times shove it into the anemone at its weakest time.

You really have to have a separate tank just for them to get years of success with them with no dramas.

I can’t emphasise this enough, if your tank is healthy and your fish are secure, these shrimp most likely will not last due to not being needed!

They eat anything, clean your hands for you,lol,very easy to keep with low temps and no ammonia or nitrites.

The ones in the past I have had, were killed by so many tank additions you wouldn’t think they would harm them!

The two that are producing many tails of youngsters hav ethe tank to them selves and are very relaxed and the eggs on them are all going to fully formed juveniles and they are reproducing at a rate of a tail full each two weeks, they are that fast when fed well with the best foods and are safe!

They are both girl and boy in each one (A sexual) and do not need a shed for one to fertilize the other, so they can reproduce at twice the speed of any other shrimp- crustacean, well not the auz peppermint shrimp, it s a lysmata as well.

They can give birth each two weeks at a stretch.

These are my three.

In the tub cleaning my hand, nothing like a little human flesh in their diet,lol.

If you look close you can see youngsters on one in the final stages and the other passed its eggs to its tail yesterday.
Fresh eggs are green as are the ovaries that show they are fertile to be seen through the carapace,(their back) and ready to break free are creamy light green to grey.

Banded coral shrimp (Stenopus hispidus)
Painted crayfish (Panulirys Versicolor)---
Harlequin shrimp (Hymenocera picta)-
Anemone crabs (Neopetrolisthes sp)

*. Temp—Tropical 20 to 28—Southern 16 to 24

*. Conditions---Most require a reef environment to ensure its food needs. Anemone crabs, candy shrimp and crayfish are not so reef dependent in an aquarium. All these can exist in medium conditions.

*. Negatives---No negatives with anemone crabs. Banded shrimp should not be paired up if you want peaceful tank and they may harm other tank inhabitants as they get bigger, Candy shrimp can be very aggressive cleaners and bother the fishes anus area. Crayfish as they grow, may push over the live rock and other inverts, scratch fish and kill anything as they rest at night. All crustaceans are susceptible to attack once they shed their shell for 2 to 10 hours after and release hormones either signalling mating or other predators following the scent back to them and eat them.

*. Positives---Anemone crabs eat some planktonic parasites. Cleaner shrimp, good workers, mainly harmless, always out if no predators. Banded shrimp, colourful no other positives. Crayfish, as they get big there are no positives. Harlequin shrimp, except for killing starfish they an excellent tank inhabitant.

*. Food---Filter feeding for anemone crabs. Shrimp and crayfish will eat and scavenge most foods, though the crayfish and banded shrimp need a little algae in their diet.

*. Comments—Crayfish, if there are no triggers, wrasse or large angels, do well, but can be trouble. All shrimp are at risk, especially the candy shrimp, as they have no defences at all when they shed and can be eaten or placed in an anemone by the occupying clown fish. Harlequin shrimp have few predators as they have a ensign based toxic siring incorporated into their nippers. Anemone crabs that filter feed are always harmless and do well if no mantis shrimps and they get on with the clowns.
