I'm ready to jump back into fishkeeping after about 4 years of absence. In the past, I've kept mainly large CA cichlids (convicts, texas, managuese, jack dempsy). I don't want to fall into the trap of getting giant tanks again. I've decided to go with shell dweling multi's. I plan on getting a 20 gallon long tank (30x12x12) or maybe a 20 gallon regular; with argonite sand, a few plastic plants, minimal rock work, and of course shells. What I'm curious about is dither fish. I'm not real excited about danios as they lack personality and aren't much to look at either. What I'd really like is a small school (6-8) tiger barbs. In the past I've kept them in community tank and liked them alot. I know they prefer neutral water, but my previous tap water was around 7.8 and they seemed to thrive. Would anyone see a problem with this? I don't think the barbs would bother the cichlids much and I don't see the cichlids hurting the barbs, about the only thing I'm worried about is the water hardness getting to the barbs.
