We recently purchased two tangs (a whitetail bristetooth tang, and a blue eyed bristletooth tang). They were both treated with copper prior to purchase. We put them in a quarantine tank for a couple weeks and also treated with prazipro. Both were doing well. The whitetail was skinny when we got it, but it gained weight quickly. We fed both of them a lot of nori as well as mysis/brine with selcon.
After about 2 weeks in the display tank, the whitetail developed spots around the eye which turned out to be the early stages of HLLE. It has been one week and it has got noticeably worse each day. And now, the blue eyed tang has just started to show early stages of HLLE as well (speckles around the eyes similar to the whitetail when it first showed signs of HLLE).
They both seem happy and stress free. They get along with each other and every one else in the tank. They are active and eat well (as I mentioned we already are giving them plenty of nori as well as mysis/brine shrimp with selcon). Also, the water parameters seem fine: 0 ammonia, 0 nitrites, 15 nitrates, 78 degrees steady, 1.025 salinity. We also checked stray voltage which is roughly 10 volts.
So at this point we are lost and and concerned. What should we do here? We are anxious about waiting longer (it has only been one week but the HLLE is getting worse).
Thanks for any advice
