Hey guys I recently scored a 55 gal for absolutely nothing, it's got black background already on it, but I might put one of those fake rock backgrounds on to take away the cornyness. Anyway I haven't really thought about what theme I want. But I would like some good ideas. I would like to with bigger fish, since this is the biggest tank I have yet to own, also if you know of any particularly mean or really rare or interesting fresh water fish, I would be willing to consider something like that. I was thinking about an African biotope with African butterflies, and maybe some type of fresh water African eel. Yes I know they may not be true eels, so please no un-needed education about that. Any ideas based on this criteria would be much appreciated.
