I have concluded that my blue spot jawfish has velvet. I've read several options for treatment, but what would be the most effective? He's in a 27gal cube, and I recently added a pair of onyx perculas (before I was aware of the velvet) So I assume I'll need to treat the whole tank. I've got a shrimp, several hermits, turbos, and many zoas, palys, and a leather and bird's nest. What would be safe yet effective for this tank?
