They don't really need anything special. Just keep the tank clean & feed the fishies & it'll be fine. But they do have very short life spans.

If you see it turn white, it's going to die soon.

If you see something like it's brains moving in it's body, thats normal, you're just observing its digestive system in action

If you see a 2nd shrimp but it looks hallow, remove it, because your shrimp has molted it's old shell so it can grow.

If you look carefully your shrimp will infact have colour on it. Some have yellow markings, red marking, & if your lucky like me, You'll have BLUE shrimp. When I say blue I mean their whole body is blue, BUT you can't really tell unless they are in an all white container hehehe

I buy 20-30 of them at a time for my 90gal tank. Usually after 6 months they are all dead. I believe they need saltwater for the young to live.

If you want a friendly pet shrimp that you can enjoy for years, get a Flower, Banana, or Rock Shrimp (they all look the same IMO).. they do get a little larger so you might want a 5g tank.
