Tiny fish swimming in my sump

[fishRus]

Does anyone think this is possible there is tiny fish swimming in my refugium which is part of my sump.
I have a breeding pair of maroon clowns they have laid eggs over ten times.
I don’t keep my tank spotless I have some different kinds of algae growing.
I have macro algae growing in my refugium that is part of my sump
Is it possible rotifers can grow in the algae and feed the the clown fish larvae ? They went out the overflow are living in the refugium ?
There are also some copepods in there also

Anything is possible, however unlikely. There is likely enough food in the macro algae to keep the fish alive, however it may not be getting all of the nutrition it needs without supplementing their diet with Chroma Boost powder (or similar). Good luck!

I have seen people get tiny fish hitchhiked in with macro algae.

Good point! If the macro algae came from Florida, then I have seen this happen with rainwater killifish (and could also happen with other fish).

It could also be Mysids or something? Pictures would help.
