I agree, you should find out as much background information on a fish, in and out of captivity, as you possibly can before keeping it. I have fish that I've read about for years before keeping and still read about now from time to time just to keep it fresh in my mind. And what do you plan keeping in the plywood? Long term or short? Cause the larger fish we've discussed would out grow it. Besides the sa cichlids.. And be careful with the pool idea, they may poke holes through it and that won't be a nice turnout.
