I just found my 15" gibby dead, she was rock hard, white in the lens of the eye, & also had a little white hole on its nose, like a small bite mark. I have a spotted puffer, clown knife, bichar & a 17" common pleco. The pleco of lately has been frequently going to the top getting air, alot. I guess I wondering if a puffers bite is poisoness or just there bodies as a defense or if you think something else is going on. Water seems good except my alkilinty is alittle high. Thanks for your help!
it must be the puffer. Can't fight their own nature. Better separate them. if you have no spare tanks, it gotta go away.
