http://www.funadvice.com/my/advice/fishfun en-us I recently set up my own aqarium and have Beta fish in my aquarium.I have 28 gallon one. I have cat fish , ghost cat fish . damation molly and red tale platy and they all seem to be doing fine. I was told my the store that beta fish only are mean to other beta or the fish which have bigger fins. Beta fish usually attack who happens to have a better fins then them so you might want to watch that out. Honestly beta get alongs good with any community fish and i have seen it many places . try it out. fishfun Sat, 25 Aug 2007 22:44:07 -0700 http://www.funadvice.com/q/beta_fish_and_compatible_fish 90529
