I just bought a 100gallon tank off craigslist, came with everything... Sand, rocks, filter, heater, air pump, stand , light , fish and food. 300$ a real steal I think. Anyway I got a large tire track eel in the tank and it doesn't like carnivore pellets but likes night crawlers, it's a big baby. I'm planning on putting my medium sized pleco (9in) and my young ornate bichir in the tank with the eel and was wondering if any problems might occur, one because bichirs can be aggressive .... Although mine is just shy, and another because maybe the pleco would get at the slime coat of the eel.... Any ideas?
