As an 'official' "too many fish for the tank" tank owner, yea, you have managed to outstrip even my overstocking by a level I wouldn't even consider.
Sorry, not slamming you, just a heads up.
Some fish take longer to reach full size in an overstuffed tank, but that isn't a good thing.
I have read that freshwater fish release chemicals into the water that effectively tell them don't get any bigger because your pond won't support your larger size.
The same poster said that for obvious reasons fish in the ocean don't have that.
I would suggest that you stick with smaller fish that max out at about 5 or 6 inches when they are mature.
One local LFS has accepted returns on South American red tails 2.5' long, a truly beautiful Queen trigger a foot long, etc.
They live in misery in a 5 foot plastic pond liner and the biggest tanks the shop has....
Human Prison cells and the official dimensions are always my goto when it comes to these kinds of fish.
If a human prisoner gets more room that your 'pet', you aren't taking very good care of your pet...
Sticking with overstocking smaller fish from different genus and denying them 'personal space' is at least less horrible...
It's part of the reason we have 200 pounds of 'holey' live rock in a 75 gallon tank.
Besides the obvious bio filtration,it provides lots of divider walls and hiding places/homes to pick from for the fish.
Best of luck with getting a bigger tank in your house. [emoji2]
I was told our 75 gallon was sufficient.
