Umbee all the way, if I ever decide to bite the bullet and shell out 300+g of tankspace for a large openwater predator... Haiti's would be next, because I've never kept them for an extended period of time. I had 4, 1 killed the other 3, and I eventually sold him after about a year (bought a ~1 inch, sold at ~7.5 inches) for an offer I couldn't refuse. Dovii, I've kept on many an occasion from 2.5-17 inches... my 17 inch male recently passed away (unconfirmed reason, eating and thrashing around 1 day, belly up the next). Awesome fish, but if I were to do another of the whole solitary fish run I think I'd rather go with an umbee or wyckii catfish.
