For the sunfish fans - it used to be legal to keep them here, and I had a tank of them. Unless you are getting them in an environment where it generally stays above freezing in winter, they are likely to need a cold period as part of their annual cycle. I couldn't provide that and would not ever keep them in tanks again. If they could thrive in year round indoor temperatures, there would be a lot of unemployed Oscars. North American sunfish are smart, beautiful creatrures, but aquarium life isn't for them, in my opinion. I regret trying.
