reef flea?

[MattsSuperman]

I am fighting dinos and have now encountered a weird looking flea looking organism in my refugium that arrange from the width of a penny to the size of your pinky nail I found in my chaeto I dont know if I should leave them or if they will cause a problem or what?
Thanks

Sounds like you have Copepods in your fuge. They are pretty harmless and some fish will eat the ones that come back into the main aquarium.

These are amphipods...great food for fish. My Copperband, Royal Gramma and McCrosker's Wrasse hunt them. If I stir one up when siphoning, they're a goner.
