So i just noticed this area on the back left of my hammer. It seems to be doing well everywhere else. Is this damage from a critter (emerald or hermit crab or peppermint shrimp) or is this possibly new growth? I'm new to Hammers but this one has been in the same spot doing well for 6 mos or so. Water parameters are all pretty spot on and stable.
Thanks all!
