I bought some blue shrimps recently, initially the shrimps were blue in colour, later some of them turn to reddish and some to brownish in colour. And only 2 remains in blue. :(
Can anyone tell me what is the problem ? Is it some to do with the water chemistry or there is others reason ? :undecided The tank were initially housed some cherry reds which I had transfered them to a bigger tank, do a 50% water changed before I put the Blues in......Tks!

Did u acclimatized them or just dump in the shrimps? Temperature?
Give them sometime to get use to your tank. Maybe they are just stress from the journey.

then, are the off springs blue or not ? Does that mean that those changed colour are females and had been hit by males? thru the library, some of these 'blue' can be 'man-made'........just wondering whether I've been con by the LSH? >(

Hi,
you probably have a blue "malayan" shrimp or one of the so called "malayan" or rainbow shrimps. There are at least two species under this name, both looks quit similar and can change there coloration but one of them, the smaller species, should be able to breed in freshwater, so it belongs to the high order kind of shrimps. This smaller species looks like this:

I bought such shrimps too a few months ago and all were blue or dark bluish-grey. Now none of them is even a bit bluish but they are grey, greenish grey or brown. It seems as if they show this blue coloration only when they are stressed like bumble bee shrimps do. Sadly, I have no offspring so far, perhaps my only male does not want to do its job.

BTW, the other, bigger and more often sold as "malayan shrimp" species looks like this:

It becomes 4cm big and can live quit long. My oldest shrimp of them lived about 2 years in my tanks before it died. I bought this female as a juvenile, so it should be about 2.5 years old when it died. They belong to the low order kind of shrimps and require brackish water in the larvae stages. This is a pregnant female, you can see the small brown eggs if you look closely onto the abdomen:

hi,

Very informatives.......so I can assumed that what I have is the malayan shrimp and only when they are stressed up, then they show the blue colour..........currently I've spotted two of them that are already pregnant, hopfully they are able to breed some babies!! :D

By the way, are there really true blue shrimps around that will remains blue when they are not stress, and would appreciate if you are able to produce some more information on these species, how to identify them so that I would not get mixed up again when I go looking for them...
