i heard its harder to breed in a 5 gallon. a bigger tank would be better and becareful with the ferts.
They're very resilient and adaptable to various conditions. You should be fine with the 5 gallon tank especially if you're not housing them with other fishes that may eat the babies.
Are you talking about CRS (crystal red shrimp) or RCS (Red cherry shrimp)? RCS are VERY adaptable and very hardy, but CRS are VERY touchy and not so easy to breed as the RCS are.
How amazing that you have Crystal Red Shrimp in a community tank! That's almost impossible. They are so touchy and hard to breed. You are referring to the red and white striped ones, right? The all red ones are red cherry shrimp - those I can see surviving in a community tank. If you are referring to the red and white ones you have really done an incredible thing! I can't imagine it! :faint2:CRS sorry if i posted wrong lol i got the words mixed up and mine have already breed in my community tank with other fish including loaches (the babes are now too big for them to get) and thats why i'm setting up my five gallon.
