I may be wrong but as I followed your other thread I felt this could be a problem. LMB will eat about anything and for darn sure, each other, but in cooler water than what they normally thrive in their metabolism is much slower, they don't eat as often and just aren't as active as a bass in 78-88 deg water. The only real way to know if your bass are maintaining the required input is get a length in mm and a weight in grams. When we plug those numbers in we'll know if weight is above or below average for that given length of fish, which will tell us either it'd eating what it needs or it needs to be eating more-it's a very simple answer there.
The answer may not be what you want to hear but it "may" answer a few questions.
