Hitchhiker fish?

I believe so

Looks like an intial phase to me ("female")

Not a wrasse since it lacks the continuous dorsal fin characteristic of all labrids. Assuming it is a brackish, killifish lay they're eggs on floating plant debris so maybe there was an egg attached to the frag plug?

Think it could have come from macro algae? I have chaeto and ulva sea lettuce

Very possible

Initial phase is technically the same thing as a young wrasse. In the scientific community we tend to stay away from male and female for hermaphoditic fish like wrasse and parrotfish since there are always sneaky males that look like females and females that develop certain male-ish characteristics

It looks like a kind of killifish to me. They are brackish fish that can survive a lot and if r2r threads are a reliable source are occasionally introduced to a tank through cheato and other macro algae, possible as an egg. I can’t tell you which kind it is but look up rainwater killifish and gulf killifish they seem like possiblities

That is definitely what it looks like. I haven't seen it today, but It hid this long. I just dont know what to do with it...

Well on the good side, it will only get 2” at full growth. As far as aggression, who knows.

I think the OP would be fine keeping it in his tank. “The little fish that could”!

I would be surprised if a killi was aggressive outside of a male defending territory from another male but who knows!

I think it will be fun to try to keep it alive.
