I've had my 6 inch aro for about 2 weeks now shes been eatin hikari brand food sticks and black worms thats all shes really touched but anyway shes got a white bump between her barbels on her lower jaw and its only gotten bigger since i first noticed it. Should i be worried or is this common. water temp is bout 79-81 deg ammonia is <0.02 ppm, nitrates, nitrites, pH, etc all are perfect, anyone seen this before or heard of it? thanks guys.
