Welcome to TR Johnny!!
Sounds like you could have a hitchhiker on your
live rock that is looking at your hermits as dinner. You may wanna keep an eye out at night and look around. Do you hear a popping sound?
I do see you are showing
ammonia in your tank- not the best idea to have critters when you see
ammonia. Always best to fully cycle a tank before adding anything.
So what do you have planned for this tank?
