(Please give a clear explanation of what is going on, include details from the beginning of the illness leading up to now)
I've had this Boesemani Rainbowfish for 3 years and he's only lived with 1 Yellow Bristlenost Pleco and 3 Ruby Tetras. On November 13th, I added 7 redeye tetras, 2 more juvenile Boesemani, and 6 Australian Rainbowfish. My 3-year-old Boesemani started acting a bit funny, sort of a bit overwhelmed at what was going on but otherwise healthy. As of 2 or 3 days ago, he started developing a white "flaky" looking spot on top of his head, which now seems to have spread to his sides, one side in particular as seen in the photo attached. Primary areas of concern are the top of his head, under his fin, middle section where orange and blue meet, and his tail. His behavior seems otherwise normal and he's eating, but I have no clue what this is; it doesn't look like ich. One of the juvenile Boesemani has started showing similar symptoms on his scales but every other fish in the tank looks perfectly fine. Thanks for any advice you may have.


To me, that looks fungal or bacterial. I'd get some Mircrob-Lift Artemis and treat that a soon as possible. The quicker you treat it, the higher the survival rate. I know this from personal experience, then again, fish disease isn't my greatest forte. Can one of the Gurus fact-check me on this? Thanks, guys. Best of luck to you!


So I noticed that one of my Ruby tetras 100% had an ich infection and the tell-tale white dots started appearing on the Boesemani above as well so I got API Super Ick Cure (the only medication I ended up using) and the tank's looking amazing. The big guy above is almost completely back to normal and the ich disappeared from the rest of the fish. Tomorrow I have to do the 25% water change that the instructions mention since I've completed both doses with the tank at 86F but I think this one's solved. No casualties, everyone handled the medication nicely. I guess I learned my lesson about not quarantining and pouring the bag of store water into the tank after they acclimate heh.
