Hi Everyone.. Any help greatly appreciated.. I have a mccosker's fairy wrasse and yellow watchmen goby in qt currently. They have been under observation with no medication. After a full tank wipeout earlier this year thanks to ick we have Qt all our new additions. This evening we noticed two white specks on the wrasse. top fin and back fin. Looks like a spec of sand, but impossible since no sand in the tank. He has ben easting and behaving absolutely normal. The only medicine I have on hand is Paraguard and Cupramine and after reading reviews decided to try first with Paraguard. Guess i'm a little paranoid after losing all my fish earlier but is there something else I should do ? I do have live rock in the tank to reduce ammonia since it is only a 13 g QT tank. Was thinking of removing and replacing with PVC? Please Help
