I'm hoping to order a couple large fish for an about 1,500 gal pond. I was thinking catfish but would like to them to be able to coexist with a few nice sized goldfish and not be too seclusive. I originally wanted to start with a few large mouth bass, knowing that they are highly predatory fish, and would love to pick up a few from a nearby lake. Does anyone keep bass? How do they do in a relatively small pond? I wouldn't necessarily be raising them for slaughter but most probably wouldn't keep them past about seven inches long. I'd also like to raise about six each season to release into the lake I fish at to help add to the large fish population. Thoughts?
