Hi all! We started here with a small 2 gallon tank for our 1st Betta. It seemed small, but far better than the bowl which he came in. Anyway, he graduated to a 10 gallon, which must've seemed like a palace all of a sudden,Lol! For some reason though, I kept the 2 gallon maintained hoping to house a new Betta someday. Someday came, and a beautiful veiltail named Lucky is it's sole occupant. His water temp is 78, but I've noticed when he sleeps, it's always on the bottom. Is this normal? Aragon (10 gallon) goes in a castle at night, so hard to tell if he's sleeping or not (think he is though). Also, do any of you think Lucky needs a tank mate, or is he satisfied by himself? As always, thanks for the input!
