Help ! Torch issue.

[Quoc Vu]

I got this torch from a show. Was nice for 2 weeks. Then he turn like this. It’s looks like algae in the middle. Did it die in the middle or a disease? Anyone have any ideas? All my other torches are fine. I have hammers and frogspawns all healthy.

I did a dip for him 2 days ago still not getting better. I don’t think it’s brown jelly.

Anyone with any ideas?

Just an update. It ended up being a crab . A fuzzy crab that would never go away.
