I just recently placed 6 green Aeneus corys into my 55g. I absolutely love them! They added a whole different level of fun to my tank! Thinking about putting some more to the tank.
55g: 5 Serpae tetras, 6 Columbian tetras, 6 blue tetras, Harry Putter nerite snail, Sonny ivory mystery snail, 5 Dalmatian Molly's.
10g: lots of shrimp...blue and ghosts
10g: 6 blue tetras, Tigger orange striped nerite snail, 5 green fire tetras and lots of shrimp, and Bonnie, Sonny and Cher ADF frogs
5g: Nemo half moon Betta purple and white.
