all fish keepers and fish lovers make procedures like these seem harmless
and they very well could be but I don't assume to know if it truly doesn't harm them or not. if it does harm them i'm sure it's very little and they fully recover
but I just don't want someone telling me those crater-like growths are like hair and nails when they are flesh, unless they actually are speaking from an educated background in the matter
Dude. Take my word for it. I wouldnt lie to you.
