Hi guys. about a 1.5 month ago, my delhezi bichir's barbel nostrols things got completely bitten off. No stump or anything. They still didn't grow back?? will they grow back or no?? with no barbels, my del is always sluggish and never moves. It barely eat any of his food even though it's right in front of it. Is this because the barbel is it's sensory organ and ithelp them to navigate and move?? what should I do??
