I picked up a royal gramma about 10 days ago and over the last 4 or 5 days I've seen this growth on it's left cheek grow steadily over the last half. He is in QT with no other signs of illness. The conditions are ammonia 0, nitrite 0 and nitrate 5. I've been doing 30% water changes every second day. He is eating and has been since day 1. I've fed him once a day with a combo of flakes/pellets as well as fresh seafood alternating every day between the two types. I also soak both foods in garlic and selcon. Pictures below and growth marked by red ring.
I'm wondering if it's HLLE
. It seems that every fish I've put in the QT gets HLLE
. I'm really questioning the benefits of a QT...but that's another thread.
