Eyelash blenny compatibility

[Onify]

Hey everyone! I have a 22 Gallon salt water tank, it's already established with a Misbar Perc Clownfish, a CUC and one Eye Lash Blenny. Now I know some people reccomend not to add 2 blennies in that small of a tank, however I went to my local LFS and they have multiple tank running on display with 3+ blennies in a 30 gallon. They said they do fine, so I was wondering, what belnnies would be compatible with most small fish, and an Eyelash blenny? There's plenty of hiding spaces/ tunneling areas.

#1 rule never listen to lfs they just want to sell sell sell
yes they'll be fine for the short time there in the 30 at lfs as they will sell them in less than a week
a 22g tank is to confined for 2 blennies
now if you had a bigger tank 40g or larger so each can establish there own territory that's different
