Yer I ended up cutting the fin, I Sedated him in a medi tank, then took him out of medi tank and cut the fungus infection of his fin and then put him back in the main tank and treated tank with api for a week, doing 40% water changes every 4 days, it took 2 weeks till his fin was fully repaired, Now he is a 14 inch beast in just 4 months,,,
