Mouth Infection

[XFeathersx]

How the heck do I prevent this from happening again? I quarantined for 30 days after a 10 day C. Phosphate treatment before putting in DT. 2 weeks later I noticed the mouth swelling and later developed into this. I couldn't get him out without destroying the rockwork. I'm at a loss as to what to do because I thought I did everything right.

Do you think this could be from physical damage?
