Hi all, my husband has a 29-gallon saltwater bait tank. He currently has two small fish in it - a juvenile bullhead sculpin and a goby. I've no idea what the parameters are on it right now, but it is cycled. The goby has worm parasites attaching under its pectoral fins, and he wants to know how to remove them. Google said to add salt, but since it's a saltwater tank, he didn't know how to do that or if it would be effective. Let me know if you need more info on the tank and I can ask him.
