I have a 36 gal bowfront and am transitioning it form a gold fish tank and when researching fish became interested in native fish. My main criteria for the fish was that they a interactive and personable with their owners like goldfish and koi are, or even like cichlids, but without needing a heater, I don't have room in my budget for that right now. I had read that many of the sunnies fell into this category. My main plan for the tank was to have one sunnie, a pair of darters and a small school of Florida Flag Fish. It is very hard to find info on these fish on the traditional fish and planted tank forums I go on, and was initially suggested a paradise fish (which is still my back up plan) so I came here to see what help I could get.
What would be the best personable sunfish for my tank, any of the three enneacanthus or either the Orange Spotted or Bantman? Can I keep them singularly? Do I need sand in my tank, right now it 1-2 mm gravel?
I hope people on here can help point in me in the right direction and see if this is a good idea for me?
Thanks
