Lawnmower Blenny Safe for Hi Fin Goby?

Ash I'm very familiar with the 29 biocube-I ran the 8g for 2 yrs. I know your limited as am I with my 26g but there are several wonderful fishes you can get for keeping a community tank. Don't get discouraged!
Personally and having experience with them the Blenny is my favorite fish. I just bought a YellowTail Fang Blenny and love her! Before that is was a TailSpot Blenny. Look at the Midas Blenny, beautiful fish! You could keep a 3" reef safe Wrasse easy with several to choose from take your time, be patient, research and choose wisely. Most of all have fun!!
