Disgusting clusters of bubbles on food

[Richy]

In my tank almost everything died of velvet. All that is left is my serp star and one velvety pajama.... there are gross clusters of what looks like clear bubbles forming on food that the serp hasnt gotten to yet..what the heck is it?

Could be bacterial or fungus, neither of which is good. I would cut back on the food.

As to the velvet, I would strongly urge you to quarantine all new additions.
