Gobies are some of my favorites. Personality really depends on the type. The clowns are usually out and about perched on the rocks, but can be very reluctant eaters when there are other fish in the tank and are usually on the brink of starvation when you bring them home.
Highfin/Shrimp gobies are great but some types are very very shy, even more so when they have a shrimp to shack up with.
Eviotas and Trimmas are some of my favorites if you don't mind small, as in TINY, but their colors and personalities make up for what they lack in size. Much underappreciated fish, IMO.
Sandsifters can be great once established but some get big and can create quite a mess. Others, like the signal gobies, should be kept in pairs and often don't live long in captivity.
I've tried the court jester types and never had luck with them, most likely a sign that I have effectively managed my hair algae growth.
Do some research and look for some unusual types that show up in stores and online sometimes.
