I'm new to fishkeeping and I already want to upgrade my 10 gal to a 55 gal. I'm still a ways off from having the new tank set up and cycled but I've been looking at tanks on youtube for ideas. (greggz has a great tank!) I want some larger, colorful, peaceful fish for a planted tank so I have been looking at rainbows. I also wouldn't mind a larger school of smaller fish to go with them. (rasboras?).
1 - how many rainbows can I put in a 55 gal? There will be a few other inhabitants such as my danios, oto and dwarf gourami. I also think the peacock gudgeons and american flag fish might be nice
2 - should I stick with all larger ones (Melanotaenia boesemani, Melanotaenia splendida...) or does it look nicer to get more types (celebes Telmatherina ladigesi, Melanotaenia praecox...)
3 - should I get all males for the colors, or is it better for the fish to get a mix?
4- What else should go in the tank for color, movement, and overall good enjoyment when I sit on the couch and stare at it?
Thanks for your help.
