I was thinking of doing something similar. Do you think getting it to work w/ a Marble Gar, Tire Track eel, Senegal bichir, pleco, and 1-2 oscar? What fish didn't work for you specifically? I was thinking of putting them in a grow out tank then moving them to a 150gal tank. Any advice on looking at the Puffer before you buy it. Also, what's the stocking on the 220?
In a 220 with all those fish??? You are would be asking for some serious trouble and major overstocking...
I can almost predict that the eel would be the first to jump ship, thenwould be a matter how lucky you are with the rest...
