My Tank Thread
My Aquarium Showcase
Im honestly thinking the tang stressed out, got velvet and thats gotten your other fish. I would expect the rest of the fish to pass in the next few days of thats the caseStress doesnt mean aggression in saltwater. That tang was in way too small of a tank even if the plan was just for a week. Tangs need room to swim, they dont they stress out and get ich or velvet and die from it and pass it to all other fish. You have to remember your freshwater tank with your fish is very different than salt, and especially when it comes to tangs
