I got a betta about 2 weeks ago off of ebay from an established breeder. He came in great packaging better than some pet stores. I noticed it looked like he had white lipstick on and didn't think anything of it but I read somewhere that it could be a fungus or something. I'm new to fishkeeping sort of. I've only had one 37 gal goldfish tank for a year and a half now and I've lost some fish to disease because I didn't know the signs. I don't want the same thing to happen to my betta Fio. He's in a 10 gallon planted tank, everything zero, temp 78, with a small filter. He is always active and swimming through the plants and the little hut. He also sits by the heater even though it's 78 should i go up to 80 maybe?
