What are the tiny caterpillars?

This photo was taken w/ an oloclip 21X macro lens. They are less that a 1/4 of an inch long - off white.
They will get on the glass and walk around as well. The don't have a 'mushy' body. The body feels surprisingly firm.
They are on a coconut 1/2 ( of which was bake and boiled/ months ago )

Plus, if you enlarge the ...there is another little gray weevil looking bug walking around.... on top of the of white caterpillars.

These ONLY are in my P terribilis enclosure.
They are living/feeding there - happily with the isopods.

I'm a little concerned as they are not a lg enough feeder for the terribilis; as a result they are multiplying.

I may be looking at breaking this tank down .
Sadly this pair of Mints are about to breed
