Ok, so today marked the death of my 2nd lawnmower blenny(had them at seperate times, not together in same tank at same time).

Both times I found them, there was like a hole through the liverock that they tried to swim through and it lo0ks like they got stuck.

Has anyone else had or has heard of blenny's doing this?

Also, is getting stuck in a lo0p in the live rock severe enough to kill them?
