Hey, y'all! I will be moving soon and will be changing my setup. I am wondering if anyone has an opinion on whether Green Neon Tetras would display better in a 20 tall or 20 long tank, or if they would be more active in either tank. They're in a 20 long now and are a bit shy, but it's not very well planted at the moment (fixing once I move). I may also increase the school size once I move since they're such tiny fish. Along with the two 20s I also have a 10 if they would possibly be happier with a tank downsize and their current school size of 13. I am open to all other energy boosting possibilities as well, so any thoughts?
