Almost lost my cowfish...

[asylumdown]

soooooo, the bony rays of ferdinand's tail that were de-fleshed in "the incident" were very quickly colonized by diatoms and turned brown and fuzzy. Now they're also starting to sprout what looks like green hair algae. I'm really not sure what to do about this, should I catch him and cut the dead tissue off, or would that only make this way worse? So far he seems totally healthy, but having part of your body literally turn in to chia pet can't be good for you long term...
