Today while feeding him I noticed a bubble like lump sticking out of his butt, it’s clear and see-through, almost like an inflated clear balloon. So I went through photos on my phone and found that it’s been there for at least 4 months now, the same size. All water parameters are normal.
He’s pooping and eating fine otherwise. Just wondering what could it be? Prolapse? Can they last so long without worsening?
