ID help, pods?

[Pat02026]

Been seeing these for the last week or so, and they are much more dense today than I’ve seen them. Guessing pods hatching? This is a coral & invert QT tank, no fish. Only been running about 3 weeks but was set up with rock from my display that had been in a blacked out but heated and circulated barrel for 8 months or so and a big bag of seachem matrix that’s been in my 3 year old tank. I haven’t noticed any pests in the qt and all coral was dipped in Fritz bug out prior to adding (all soft corals so far) but did add a bunch of snails and crab from reef cleaners, their 120 gallon cleaner package.

From what I can tell it looks like normal zooplankton/pods but hard to totally tell since YT compresses stuff...

Hermit crab spawning? In my profile pic, this is what they look like when the female ejects the shrimp like floating spawn. It's almost as if the male pushes them out. Happens just around lights out every few weeks in the hundreds. They only last in the tank a day or two. Good food for fish. They look like little vertical swimming brine shrimp. Similar to what ghost shrimp babies look like. Swimming pods are usually smaller and phototaxic. Amphipods are usually rock hoppers and much larger than copepods.
