Copepod overload

[mssamurai]

I've recently had a horrible ich outbreak and lost majority of my fish. Remaining are in QT with copper and doing well 2 weeks in. I noticed yesterday an invasion of Copepods, or what I think are Copepods. Can someone confirm for me and what's causing the sudden increase? They are everywhere!! It looks like snow in the tank. I know these are beneficial just want to make sure that's what they are.

It zips by to quickly to ID but it's not a Copepod. Maybe an Amphipod. Any increase in pods would be due to a decrease in predators.

On a side note - creators of vertical videos should be fined and/or jailed.

Okay. Either way beneficial and nothing to worry about then? So possibly an increase since the tanks are fallow. They are in both my tanks. 46 gallon bow front and 135 rimless cube. I've never purposely introduced them into the tank so was unsure where they came from or what they were. I'll try to get a better picture ( non-vertical, lol).

Good high quality live rock usually hold eggs or larvae of Copepods, Amphipods, Isopods, Ostracods, and Mysid Shrimp.
