Now it is time to stop bashing this new member and try to help instead. I agree that "releasing" a fish into a natural water way is a bad idea. What that does, even if it is like the water the animal came from, is allow anything that may be in your tank to infect the natural populations. Once a fish is removed from the wild, it can never go back. Sorry but that is a simple rule that should always be followed.
Rehoming fish that are too large for a particular tank is a challenge for many people but is better than any other alternatives in my mind.
Things that can thrive in that tiny tank would include Heterandria formosa, least killies like this one in my tank. They grow to a whopping 2 cm long at the most and are nice little fish. You could keep 2 or 3 pairs in a tank that size.
Another suggestion would be any of the tiny shrimp that have been so popular the last few years. That is something I do not have.
Yet another fish in my tanks that would work in small numbers is Xenophallus umbratilis, golden teddies. A simple breeding pair would work at about 1 inch each. My avatar is a male and this is a female.
