I have a 29 gallon bio cube freshwater aquarium with live plants. Its dimentions are 20"L x 20.75"W x 19.25"H with two 36 watt fluorescent 16" lights. I have had it for a while now but each time I get new fish most of them die leaving only a few left. Right now i have 2 Rummy Nose Tetras, 1 Bleeding Heart Tetra, 3 Flying Fox Siamesises, 1 Bristlenose pleco, and 3 algae eating shrimp. I want to get some new smaller community fish that would go well with the fish I already have, but I don't know which fish would be compatible with the fish I already have. If you have any suggestions for what fish I could get, I would be glad to hear them.
