I was just at my LFS and saw a krib in a tank full of africans much bigger than him and he looked terrified. I don't want him but I have the room for him so I'm thinking I should go back and rescue him.
goggle "blue fin kribs". all the sites that list a size for your fish will say 3.5-4 inches.I have 3 pelvicachromis sp. "blue fin" kribs already but they are 1" at the most and I don't think they will get much bigger. I just wish I had something else to keep him in but I guess a 10gallon won't hurt.
