I have kept these in the past, but they have died from a GBR I used to have. I am thinking about getting them again, 3 for the moment(3 for 15$, I can wait to get more). My only question is, is that I have a number of bottom dwellers. My two otos, stay under a big piece of driftwood(look in the Photo Album forum to see my tank, Smalltank3's 10g Planted tank), except come out every once in a while on the glass, the two pygmy cories move around but they are very small and are sometimes hard to find, and my SAE is almost every where all the time lol. So I was thinking if I could start out with 3 Cherry Shrimp with the bottom dwellers that I have now. I've heard they breed like rabbits so I'm thinking of just getting 3 for now; if I can.
