There is a public aquarium 15 minutes from me that takes donations all the time, also my lfs has a couple large show tanks that have my previous fish in themI never said the tank was undersized for any of the individual fish. The entire stocking plan is what makes the tank overcrowded. And although it can be easy to rehome fish, it gets more and more difficult the larger a fish gets. It’s irresponsible to gamble the well-being of an animal on whether or not you can rehome it or it’s tankmates down the line.
