I would just let it float till it sank. Simpler than the headache trying to get it to stay down will cause. I had a piece float in the tank for over a month, but was worth it in the end.
I think we'd all love to be able to catch those fish you mentioned, but only around one state you can catch 2 of those 3. Lmb can be caught in any state in the continental US.,
Whoa very nice. I would love a 450 gallon native tank. Get some substrate in there and get yourself a bullhead.
Is this bar going to be outside like in the pic? May have an algea problem.
