I got the shrimp in the first two pictures a few weeks ago in a bag of Red Cherry shrimp. At the time she was only slightly larger than the other shrimp, but a very different color from the others, a brownish/red, with stripe on back. I couldn't get a semi clear picture of her(I think it's a female) until tonight. It's now almost double the size of the RCS & it's even bigger than my young Bamboo Shrimp. What type is she? She seems to stay on the back of the filter 99% of the time. And I need someone to help me determine if the RCS in the 3rd pic is male or female. Thx.

Yeah, shrimp in the third pic is a tough call but looks more on the female side.

Possible the shrimp you have is a rainbow shrimp, especially if she has ever changed colors. Or, something else?

Granted, some cherries can grow to be pretty huge!

I don't think it's a filter feeder, I have 3 Bamboo Shrimp & this shrimp doesn't eat like they do. It does look VERY similar though.

The only change in color that I noticed is that it looks slightly more brown now.

I'm not sure if we can accurately figure out the species based on the current photos.

This site has a list of various colors of Neos
Color list for shrimp Neocaridina heteropoda

vs some wild type cherry shrimp
Neocaridina Heteropoda .:. Freshwater Aquarium Shrimp Species Information Page

vs a Malaya Shrimp....
Malaya Shrimp .:. Caridina sp. "Malaya" .:. Freshwater Aquarium Shrimp Species Information Page

Basically, it's kind of hard to pinpoint exact species. Judging by size, we should be able to assume it's female. If it ever becomes pregnat and you are lucky enough to catch the eggs hatching, and the female produces baby shrimp that look like miniature adults, then it's safe to assume it's not Malaya.

If it is Malaya, then it would depend on whether or not you have any males in the tank that could mate with her, and if you ever notice any larvae (head down, tail up) floating around in the water column (difficult to see without a flashlight when the room is dark), then Malaya. The larvae would soon develop into miniature adults and grow up like normal shrimp.

If it looks that similar another possibility is this shrimp has been damaged. Bamboo shrimp have those very delicate fans (as you know) and it's not uncommon for them to be damaged. So it's possible the little guy has broken arms. If you can't identify it, give it a molt or two and they should regenerate.

maybe you got yourself a mutant pink striped skunk cherry shrimp? if it breeds out babies with the pink stripe you just found a new color to make a fortune with.
