i don't know but i've heard of people puttin ghost shrimp in there. Not sure if it's a good idea though.
I had a phonecall from a friend the other day asking about triops, and would a 1 gallon tank be all right for them. I was a little confused (triops are those brine-shrimp type things). Especially when she said "No, not triop
s, triop, I have one triop".
"Are you asking me if a single triop would be OK in a 1 gallon tank?" I asked. I was thinking the woman was mad - I mean, I was looking at my Sea Monkeys thinking it's about the same size, maybe a little bigger, and I couldn't understand why she had a problem.
"It's 3 inches long," she said, "and shows no signs of getting any smaller."
I haven't seen this beastie, but I don't think its a triop. Maybe something else got into the eggs and hatched out. She did say her giant "triop" got fat by eating all the other triops.
Anyway, the point of this little tangent is that maybe you could consider an invertebrate of some kind?
