Hello, I'm new to fish keeping. I have two betta tanks already, and will soon be getting a 29g aquarium that I will set up as a planted, freshwater community tank. I've still trying to decide how to stock it once I get it set up (planted, cycled, etc...) I'm pretty set on getting the following: 6 - panda corys 12 - cardinal tetras 1 or 2 - TBD centerpiece fish I'm not sure what to do about a centerpiece fish. I LOVE the look of the opaline gourami, but I've been reading that they are too big and/or too aggressive for this set up. Thoughts? Does anyone have suggestions on another centerpiece fish? I would like a larger fish (4-5 in) and colorful (blue is my favorite color so bonus points for that) and does well in a community.
