Teeny tiny bugs crawling on glass

[sketsy35]

Okay now my yellow tang has died. this morning I woke up and there are organisms crawling on the glass. some of them look like little slashes moving the others are bigger and developed ....they are all clear and the biggers ones have antennae and cilia they almost look like clear centipedes. What the heck is this? I think these things may have killed my tang. there is clear/white stuff on the rocks that was not there before. could these things have grown off of there? Also we have been using frozen shrimp. Could there have been shrimp eggs in the frozen blocks that have hatched???
HELLPPP

JWT is right most "bugs" you can see are good. You cant see ick or velvet with the

eye off the fish. What are your water readings? Ant reddening on your tang before he died?

A while back I had a regal tang die. That same day I had a hundred black worms in my aquarium that weren't there before. he was the only fish in the aquarium (hospital tank). I never found out what these were. Are these different than what Sketsy35 is talking about?
