What is this? Found it in some lake water I pulled with milfoil and duckweed to observe. So far I also believe I have Dikerogammarus Villous which I'll try to get a pic but they're very very tiny. I'm in south east Michigan by the way.

Amphipods by themselves are fine. The threat is what the amphipods may have picked up in the wild. Like most aquatic invertebrates fish will happily eat them.
As with most wild caught things brought into Aquaria, there's always the risk of chemical contamination, parasites, and disease.

True. I'm going to quarantine everything in a small tank.
