i have a small blenny maybe about 2" - 2" 1/2 the last couple of days i havent seen it and tried looking everywhere in the tank for it and i really cant spot it anywhere.. im thinking it died somewhere maybe in a hole in a pcs of LR or something, if it ends up just rotting in my tank will it crash my system?

If it is dead, and you cannot see it anywhere, and you have a decent clean up crew, there is nothing to worry about except why did the fish die. The clean up crew probably did their job.
On the other hand your blenny is a known jumper. Tank open top???
Looked around on the floor???
Have any pets that could have eaten it if it did go carpet surfiing????

I have a school of chromis in my 75 gallon reef tank. One day I came home, and one of them had a very bad injury. Not sure what happened to him. After a couple of days I did not see him any more. A couple of days later I moved everything to a different tank. There was nothing left of him. It does not take long for your clean up crew to do their job. That has been 2 months now, and everything else is doing great. I wouldn't worry about it either.

not sure why it died if it did, it did look a lil skinny but it was eating alot off the rocks and glass.. it is a open top tank and looked around the tank and nothing no other pets.. how big should my clean up crew be.. right now i have about 5 hermits maybe 10 cerith snails and about 5 nassirus snails.. i have a bully hermit crab amoung the bunch and not sure wich one is kill the hermits off.. i was thinking about geting 10-15 more nassirus snails.

Id go with more hermits than nassarius , more above the sand then below it that will need cleaning. I do believe
