My Talbot has been keeping to himself for a couple of days & not eating. Today, he seems to have 'swollen' white lips. Cant get a great pic, but have 2. [How do I attach pics to message?]
Normally eats pellets & frozen. Now, swims up to the pellets, but then turns away.
150g tank started in Feb. Last addition is a blue tang about 4 weeks ago. Everyone else seems happy/active.
Ideas of what it is? Treatable? Other fish in danger?
Thanks in advance.
