I posted this a NANFA but didn't get any helpful responses. I figured I'd post it here and see if you guys/gals have any insight.
I'm planning an outdoor water garder/aquarium. You can see the attached picture of my plan. It is about 5000 gallons and will include floating and submerged plants along with driftwood and rocks for cover. I plan on keeping species native to lake wylie,SC as I live on that lake and want to keep fish native to the lake. The primary fish will be largemouth but I will also try to include crappie, catfish, bream and any other local fish I can find all fish ideally will be raised from fingerling.
Now to my question. I would like to breed Nightcrawlers and Fathead minnows and live feed all species. I'm not too concerned when the fish are small but as they grow will I be able to breed enough minnows and nightcrawlers to satisfy them. Does anyone have experience with how many or weight of food adult largemout eat. I can use a cast net to catch additional baitfish if needed but I'm trying to figure out if I can sustain these fish without having to buy baitfish every week. I will also try only to keep as many fish as I can handle.
Part two-- is there any chance that sunfish, blue gill, shiners, and minnows will be able to breed and create a self sustaining environment if provided with enough cover? This is probably a longshot since the balance would probably need to be very drastic for this the work like hundreds of bream to one bass but I though I'd ask.
