Hi! I have a neon tetra with a coating of something on its body. My readings are ammonia and nitrite 0 and nitrate 5. My tank is heavily planted and I have about 15 neons total. This neon is the only one that has this issue. He is eating and swimming normally. He doesn’t act sick. He is colored nicely and not rubbing up against anything. He just appears to have something all over his scales. It’s almost hazy. I thought it was ich so I raised the temp a few days ago; but now I’m not sure. He hasn’t shown any difference yet, and if it’s a fungus I need to lower the temp. So I thought I’d see what some of you thought. Thanks so much!!
