I'm planning on setting up a Gulf Coast Pygmy Sunfish tank in the near future. Apparently there are very few people who have experience with these fish and I'm struggling to find consistent information on them. So if anybody has experience with these fish could you please answer a few questions? What size tank would be ok? I'm planning on having a small aquarium if possible as they only get to a very small size, but I want enough space for a few dominant males. Should I keep them in a heated or cold water tank? And how much are these fish to buy? I don't ever see them in fish shops near me and I can't find any prices on the web.
