hey so my 3in GT has what looks like a little tab of skin hanging out from under his left gill plate. At first i thought maybe flukes, but i don't think thats what it is. Are they maybe enflamed? Sorry about the pic quality, but he has little interest in staying still...
It is diffacult to tell what that is from the picture and might be why you have had any responses. A very clear close might be of more use. Is it behaving normaly otherwise?
