Tiny white bugs on tank glass!

[Johnny3334]

Hello i have a fish tank that is about 3 months old and recently I got these tiny thousands of white bugs all over my glass wall and i was wondering what they where. They seem to have a tail with 2 little antennas and move pretty quickly. I have 2 clowns (1 orange and 1 black) and 1 diamond Goby in my tank, I also have 2 turbo snails and a green star polyp frag. It is 75 gallons with 90 pounds of live rock and I have a Sump with a refugium. I also have about 100 pounds of fine oovite live sand, 2-3 inches deep. My water parameters are all good with exception of my nitrates being at about 15ppm. Please help thanks!

Sounds like cope and amphipods. Good guys to have in the clean up crew.

Oh man that's good to know. Do you think they will keep thriving in my refugium Themselves?

Sometimes they do, sometimes they don't. Chances go up if nothing is consuming them.
