Should I be concerned lol - What is this creature in my rocks?

Hello all, TL : DR, I've had a lot of different tanks, always end up coming back to to the hobby seemingly more intensely each time. My name is Griffin, been in the hobby off and on since 2010. Started with freshwater tanks as most do. For a birthday present got an Aqueon 29 gallon with hang...
