Where are you getting this information? I target sunfish all over the state of Texas and Arkansas, I am good at it, and there is not a single public water fishery nor a privately managed water body that I have fished or heard of that has average 12" fish. There are fisheries I have access to where I can get Coppernose & Redear over 11" and hybrids over 10". But they don't average that size. Don't get me wrong, I'd loved to be proven wrong on private water having an average of foot long Sunfish. I will start figuring out a way to fish it as soon as it's verified.
I understand your point to the OP that the tank is much to small for LMB or BG's, but why go so far over the top that people (like me) who fish for/collect/keep natives must jump in and say something?
And to the other poster that said LMB get almost 3ft, no they do not, they do not grow that big in a home aquarium. They don't grow that big in Falcon Lake lol.
I have high praise for native fish. I keep them in a 1100gl Koi pond, a 250gl, 160gl, 40gl, 32gl aquariums. If anyone was going to brag on these fish it would be me, but y'all probably cant even keep a poker face when you post some of these exaggerations.
And to the OP- Good rule to keep, ---> Do some research before you put a predator in your home. I would rather have a long tank than a tall tank when keeping natives, and must have a strong filtration system, Sunnies/Bass/Cats are dirty. What I mean is, some 75gl are better than other 75gl aquariums. Gook luck to you, natives are a blast to keep, you just happened to pick some of the more demanding species, and commonly collected species that have unfortunately ended in dead fish stories because people didn't understand their fish requirements.
