So I'm trying to get over an earlier issue that I had with using the wrong kind of silicone (GE II) and not letting it cure long enough.
One fish that survived doesn't look too good: a Koran Angel. Looks like blotchy skin with discoloration. He remains active, is eating normally, and doesn't "seem" to be suffering at all. Any ideas?

I am doing PWC
each week. I also installed a new UV
sterilizer this week as well to plan for future needs.
