So I was thinking that getting a catfish would be cool to go with my ray(s). I don't have anything yet, this is all still in the planning process. Other tankmates will be a senegal bichir or two, a ghost knife, and maybe a moonlight gourami (oh they are pretty). I'd like to have a catfish but it needs to be big enough that it can't be swallowed by the ray or bichir. It also needs to not need a lot of hiding places because I hear stingrays just don't like leaving decorations alone. My decorations will probably be a large piece of driftwood with some hidey holes drilled into it, or some pieces of pipe attached and covered with moss to hide them. I'm considering making a large cave network of slate by glueing the pieces together and then attaching the whole setup to the bottom of the cage. I know that because of my criteria I'm really limiting if not completely killing my options, but any ideas? Any at all? It'll be over 200 gallons by the way. How much over is still in debate. Also it'll be long and wide (stingray right?).
