Your mother is an hamster and your father smells of elderberries

Just made my day!
Now to the OP, your 1st tank, "2 BP's and lots of community fish" is way to vague but is potentially overstocked.
2nd tank: Pearsei's get huge and fast. What are the dimensions of the 65g?
3rd tank: sounds good to me
All this depends on filtration as well, how are all these tanks filtered?
 
my 30 gallon was not my first tank i used to have 2 small tanks but i got rid of them and i got the 30 gallon after i got my 65 gallon and my most recent tank is my 75 gallon my 75 gallon has 1 emperor 400 filtering it my thirty has 1 top fin 30 filtering it and my 65 gallon has 1 2215 eheim canister filter
 
None of your tanks are large enough to properly accommodate a common pleco, so I'd say the latter two are definitely overstocked.
 
the 75 gallon came with all the fish that are in it now and the stupid peto guy tricked me into buying a common for my 10 gallon a long time ago then i moved him to my 65 gallon
