Just bought a FOWLR 77 gallon.
Just starting to contemplate what I want to put in there (if anything at all) with the fishes that came with the tank. (picasso trigger, purple tang, goby, bi colour angel, and my own copperbanded butterfly.)
Am playing with the idea of a eel perhaps?
I am just starting the research phase and was looking for advice around eels.
Never really had thought about them before so I have no idea what their needs are and what, if any, tank mates they will endure.
Are there big differences in the species? if so, what types would u suggest?
Any info would be greatly appreciated.
BTW, I am not saying that I am going to get one, I am just toying with the idea and want to get people's opinions and ideas on it..
thanks again,
Neal
