sorry to hijack this thread. thxs autumneffect! i realized i have one more question: can they be trusted with small fish (danios and tetra) or would they make a habit of snacking on them?
If you are going to catch some sunfish for your tank, I would recommend staying away from Bluegill. IME they are very, very aggressive to all fish, not just other sunfish. The 2.5" Bluegill I have is way more aggressive than my Greens (most of which are larger than it).
