In Huntsville , I have an 800 gal; 36" deep. I have kept swordtails and danios for 3+ yrs by putting on foam sheet , and ,ocassionally 200 watts. This year we netted out a few hundred tropicals and did nothing to protect the pond .I expected to have only Koi in the spring. BUT, just looked with a flashlight and saw 20+ swords (in one spot), I don't think there were danios. I haven't measured temps , but I guess it got close to 40F !!!
Maybe I can sell "cold acclimated" green swords at a premium $ ?
Right now ( Jan 14) it is 48F.
