I recently overhauled my tanks to fit three Betta to a 10g.. the critters all seem happy and well adjusted to their new homes. :) But I'm still having problems with filters.. I had some sponge filters that I loved, but the fish didn't take to them too well because of surface turbulence. That and Flair pretty much nose dived into the top of the filter and tore his fins all to pieces. At any rate, I'm looking for a filter that would suffice for a 10G that's divided three ways (two dividers).. and that I may not have to put a baffle on. I'm not that great of a craftsperson and I'm not sure I'd be able to pull off a baffle.
Would I need to buy one big one, since my tanks are divided, or several small ones? My dividers are made out of two sheets of glued plastic canvas.
So far I'm doing 25% change on all of my ten gals daily. I'm just worried about ammonia levels etc. :C
I also have a 20g divided for five fish, finding a filter for that would be great too.
