Segmented blenny in 15 gallon?

[Common Blevil]

My LFS is selling this fish, and i love it the most from all of the other available reef blennies. It is also pretty cheap compared to blennies in the ecsenius genus. Should i get one? I also have two yellow clown gobies, and maybe in the future will sell one(they do not want to pair up). Salarias will not fight with gobiodon, right? I did not find any cases of gobiodon/salarias aggression. Photo of the tank with lamp off
