I couldn't stick to one continent of fish personally lol. I'd say get some bichirs and, maybe a African pike, I'd like to know your experience if you do, cause I'm still waitin for the right opportunity to get a gold wolf lol, and my African pike is the only one who swims around much, the black comes out at night mostly he only cruises around the bottom during the day. They look good and glad to have you back lol nice tegu as well, I had one when I was younger probably grew it to 2' and then sent it to someone we know who was real into reptiles. A school of odoes and golds would be cool though I don't think they'd school together.
