I'm new to the saltwater aquariums and I have had my 55 gal up for about 2 weeks with a canister filter. I have live rock live sand 5 hermit crabs an intank refugeum and 2 green chromis. I figured I would get a scooter blenny because they are awesome. So I brought a blenny and some copepods. Got him home, acclimated him. I turned him into the tank. I also put some baby brine shrimp in there and he started eating them right away. I turn off the tank lights before bed and this morning I woke up for work turned the lights on. No blenny figured he was hiding. Got home from work still no blenny. I moved all the live rock took it all out sifted the sand with my net still no blenny. I can't find home for the life of me. Any idea where he could be?
it may be hiding inside one, where you can't see it. My gramma does that.
