Steve,
I'm starting to finally put fish in this tank. I've had a tribal blenny and a red fire fish forever and I'm adding a flasher wrasse (most likely McCoskers) this week or next. I also have a very small skunk cleaner shrimp. I need something to live in the bottom portion. I have a ton of caves and hidey holes down there, but not a lot of sand. My sandbed is half an inch to an inch and is even bare in a few spots.
I was thinking about a jawfish. What are your thoughts on that with so little sand. Would a shrimp goby (without the shrimp this time) like the YWG or Yasha be better? Would they have any issues with the tribal blenny?
A jawfish would feel very insecure without the capability of making a home. A shrimp goby would do fine without a shrimp and there are a large variety, all with the same behavioral profile. However with the aquascape your describe, I personally would opt for one of the Wetmorella complex because I love their semi-reclusive behavior patterns. Long lived and wonderful coloration.
