Anybody got any ideas. I know, sounds like ich. None of the other fish do it. The Clown Loaches do it just occasionally and on only one item in the tank - a plastic tree stump. All of the fish are relatively new - purchased within the last 2 months. The tank has been up for 3 years. I recently restocked from Oscars to a community tank of smaller fish. I did have Ich about 2 weeks ago that killed one Bala Shark. My temp was 76 and no salt in the water. I've raised the temp to 80 and have about 1 tablespoon (3 teaspoons) per 5 gallons of aquarium salt in the tank and it's been that way for about 2 weeks. There is no visible signs of Ich in the tank anymore. But as I said, the Clowns still occasionally rub off on the tree stump. I know they have reps. as being goofy...are they playing?
