Cloudy Fin on Porcupine Puffer -HELP??

[BluerSkiesAhead]

My porcupine puffer is acting completely normal and eating just fine, but he has weird cloudy patches in fins that weren’t there yesterday. Does anyone know what this is??

White filmy areas should be viewed with suspicion. It can indicate a bacterial infection is beginning. If the area increases, changes to red or black, treat quickly as these things can go sideways rather quickly.
