What county are you in? Do you think the Attu could coexist temporarely with a 5"B.Bagarius, a 5"H.Mal;(Wolf-fish)?? and how long a drive to you, from Pasadena? Holla back..
I am in San Luis Obispo county. You are 3 and a half four hours away. He may be able to get along but there is risk involved, these guys are not very thick yet. I don't usualy trust wolf fish. Wallago attu are incredible jumpers and require a tightly sealed tank.
