i recently aquired a red tailed catfish from a friend who was thinking about releasing it............ i almost hit him....but i took the catfish instead. i plan on putting it in my 3,000 outdoor pond. i live in texas so the temp should be ok..... but i am at a lost for any information about this fish. like its maximum size, feeding requirements, and temerment. the pond has two inhabitants. a large sunfish and a 25" channel cat.....will this be ok?
