Hello everybody. I'm new (to the forums & to the aquarium world), and had a couple of questions. I bought a betta five days ago, and now he is sick. I think he has parasites--maybe velvet--because he is darting around and trying to scratch up against the gravel. But I don't see any white spots on him. The top of his has darkened. I have him in one of those little tanks that are less than 1/2 a gallon (didn't do my research first). So I've bought a new 1gal tank and some Quick Cure from Wal-Mart. Do you all think this medication will cure his problem, and how often should I change his water during the treatment? I'm thinking that I want him completely recovered before putting him in the new tank. Also, do bettas do well with air pumps?
