I have a beautiful, docile, male, Betta named Fitzy. He currently lives with a few snails in a 5 gallon tank but i recently set up a 10gal planted tank that I'll be moving him into. I was thinking of getting some Albino Cory Cats (3-4) to help keep the bottom clean. I was wondering if I could add a few Mollies or other similar type fish without the bioload getting too high? There are a lot of plants. Would it be better if I went with some Ghost shrimp instead?
