I think I've completed the tank to where I want it to be. I've got 5 Tiger Barbs, 3 red platys, 2 african dwarf frogs, a Raindow shark and Chinese Algae Eater. The only problem I have in the tank is the CAE. It doesn't bother the frogs but chases the other fish away from the bottom of the tank. The place that sold me the CAE didn't say it would be so territorial. It really only got aggressive when I put the raindow shark and 2 of the red platys in the tank. It calmed down though and stopped caring about the raindow shark to my suprise. My question is will the CAE get more aggressive as it gets older? It seems fine now but I'll get rid of it if I have to. SeanJohn79 2010-08-16 http://forum.aqua-fish.net/?topic=20-gallon-tank-with-a-cae#2 You were given bad advice, the CAE gets more aggressive and territorial with age. The Rainbow shark will be the same but as it is the only bottom dweller you may get away with that one mickey 2010-08-17
