Parasites or Good Bugs?

No, not copepods, which were also on the glass, unless immature copepods have the ability to swim. These little bugs sort of vibrated against the glass, while some swam into the water column, then back to the glass. I was watching some of our big transluscent-white flatworms approach the tiny bugs, thinking the flatworm would eat them, but it passed them by everytime. Gonna keep watching those itty bitty bugs over the next few nights to see what they grow up to be.

You know, while watching the tank over the last few nights, I've seen red swimming worms about 1/8" long and white swimming worms about 1/4" long. PLUS!!!!! We have found another hairy crab in that tank It doesn't have red eyes though and has not taken the bait in the glass of food we have set up to feed the tank. This crab is either very smart not to get caught in the trap or is not a predator.
