So right now I have a 10 gallon tank with 4 zebra danios and 3 platies +3 young platy fry. I'm for sure getting a 29 gallon within this month. most likely next week. Anyways I've been thinking of what to do with my 10 gallon after I move all the fish to the 29. At first I was sold on making it a fry tank for my fry to grow up in. Now I've started thinking about shrimp and read a bit about them. So part of me thinks of just making the 10 gallon a fabulous shrimp colony tank and another part of my thinks about just having them live in the new 29 gallon with my fish. What got me thinking about this is when I was thinking about how I would stock my new 29 gallon with the fish I already have. I was thinking of going with something different besides platies. I looked at dwarf gouramis, chiclids, mollies and tetras. While I looked at these different fish, I read that mollies would need more space, tetras need to be groups of 6+, and chiclids and gouramis were a bit aggressive. All of this gave me the impression that maybe I should just keep my lovely peaceful platy ways. So I started thinking about shrimp and figured out they do great alone in a 10 gallon. Another thought that got me leaning towards the shrimp tank was that I thought about how difficult it would be to continuously move fish from the 29 to the "fry tank." So what should I do make the 10 gallon a shrimp tank or a fry tank? Is a fry tank really necessary? Any ideas on different fish to stock my 29 with the fish I already have?
