I've convinced myself that I should move up to a 29 gallon tank. I'm planning to move my three platy (ffm) in, once the cycling is finished. Would I be alright to include another three platy (total 4f2m) in the tank? I'm thinking that 6-8 tetras would look nice in there, too... possibly neon, cardinal, or rummy nose. With that population, do I have room for a bigger fish or two? If so, are there any that you'd recommend in particular? The plants are all plastic or silk, as I'm not into gardening. Thank you for any input.
