I never let it drop below 50. But usually around 70. I am happy to report that my little homie is pretty much cured. I’ll lost some pics later today. I have been using plenty of cod liver oil and fish oil in his foods. But added some capsules of vitamin A to his food, lots of seafood, and I went out and bought this super vitamin b complex and crushed it into powder and sprinkle that on as well (all the vitamin b’s in one tablet crushed into powder). And have him super long soaks with an antiseptic called betadine and now he doesn’t even look like he went through anything. His color is back, had a full shed, and there is one small layer left on his tail we are taking care of right now. He’s doing amazing and growing like a weed right now and seems way happy
