I am in the middle of a 55 gallon tank build. I have been planning to make it a betta sorority (which I I am still seriously considering), but my husband told me tonight (as he was staining the tank stand he just built for me...) that he was not too excited about that idea. It is always better for me when he is excited about stuff because then he will be more forgiving when the budget goes over >:;a>. So, he once told me he thought the congos were cool. He also likes the African Rift Cichlids, but my water is very soft and I do not want to have to worry about messing with the water chemistry all the time. Long story short, what could I put in the 55 gallon with a school of congo tetras? Centerpiece fish, etc.?
