Hello everyone, today i noticed a bubble like mass on my Vampire SRD flowerhorn, it was at the bace of the pectoral fin and I'm scratching my head to what this truly is.
Any suggestions would help, its a medium bubble but its concerning me (5mm thick)
I think its something to do with either excess protein, as flowerhorns can develop bubbles of their nuchal hump due to that.
Let me know

So your saying it could be something to do with a parasite? maybe worms?
