Tadpole, fish, or something else?

Make sure to de-chlorinate the water and when you do water changes, be careful, sudden change in water temp can cause the fish to go into shock, more so for fry.
Good luck and keep me updated if you could.

Thank you, about half of their water got changed out, and they are swimming around attacking pieces of fish food and then eating them.

How's the fish doing?
