So i have a 20 Galloon Tank. I have One female Betta , three corydoras , and One pearl gourami. Is that over stocking? If it isnt. Is it possible id be able to get another pearl Gourami?

Hello Fresh...

If you've done your homework ahead to make sure the fish will get along, checked the adult size of all the fish and their water requirements, then you could add one more, small fish. Make sure you keep up on the water changes. I change out most of the water weekly in my tanks that require it. Large, weekly water changes will maintain a steady water chemistry and keep your fish healthy.
