Hello! I currently have a powder blue tang in a 20g Long QT. I bought him from petco and for the first 3 days he looked great, beautiful color and everything. I then noticed slight twitching and scratching against the pvc in the tank. With that being said i decided to start treatment with Ruby Reef Rally Pro and Kick-Ice combo. Within 10 minutes of dosing the Rally Pro i could noticed these blotches showing up on his sides and face. He wasn't looking good and i wanted to get him some immediate relief. I decided to do my first ever fresh water dip. I dipped him for about 4 minutes, and though he was struggling i could see ALOT of white things falling off of him. After the fresh water dip, I decided to start using Prazipro for the Flukes ( the next day to let him relax a little ). I did 100% water change during the freshwater dip. Here we are now, day 2 of Prazipro and im seeing what appears to be Fin Rot. My question is do I let Prazipro run its course for the next 5 days and monitor the fin rot or do i do 100% water change and start treating with Kanaplex? I've been reading and have heard mixing these meds is a no go so what do i do here? Im just trying to help this poor fish. This is my first go around with medicating fish and fresh water dips so any advice is appreciated. i currently have a 210g tank being cycled and a 32g bio cube with a pair of clowns, watchman goby, mandarin dragonette, 6-line wrasse, cleaner shrimp, corals and nems but never quarantined for my bio cube and have been lucky. im trying to do things right for my 210g tank.
