I had a 270-gallon saltwater FOWLR tank recently set up (about 8 weeks ago) at my office. There are two puffers (porcupine and spiny box), several rabbit fish, 2 Klein butterflies, a pin fish (long story), and a snowflake eel. All of
the fish in the new tank were in 5 different "grow out" tanks at my office for at least 6 (the puffers I had for closer to 9 months). There were no outbreaks or fish loss in the grow out tanks over that 9-month period. After the new tank was set up, I slowly (over 4 weeks) moved fish to it along with live rock from their tanks. There is a lot of rock in the tank (tt is all CaribSea LifeRock or something like that)
Last Wednesday when the maintenance company was "cleaning" the new tank, he noted that my porcupine puffer had small dots on it. He thought it looked like ich. I asked the Owner of a LFS store (located 1/2 mile away) if he would stop by and look at the porcupine puffer (he sold me the puffer around a year ago). He said it looked like ich to him but could not rule out velvet. We have since noticed similar dots on the spiny box puffer and one of the Kleins "flicking" against rocks. Both recommended hyposalinity to treat the ich. I slowly lowered the salinity over 5 days to get it to 1.009. It has been at this salinity for close to 48 hours now. Since reaching hyposalinity, ammonia has been going up slowly. This morning Ammonia was at 1 ppm (determined with hanna checker and lamotte), nitrites were 0.2 (determined with spin touch), and nitrates were 15 (determined with spin touch). I began dosing with Prime and Seed two days ago.
With the exception of the spiny box, all the fish are acting normal and eating. The spiny box is hiding a lot and didn't eat last night.
There are no corals or inverts in the tank.
Can someone help me identify if this is ich, velvet, or something else and help me prepare a treatment plan? I still have a few of the 40 gallon grow out tanks but have gotten rid of a couple.
Thank you in advance for your help.
