Thanks Leslie and Pete for all the information. I have looked up some of the fish you suggested, the catalina goby is beautiful!
I talked with my husband about this and he thinks that if were setting up a tank for these marvelous creatures it should be BIG. Something over 150 gallons. I agree, but that also means the whole project will need to wait… possibly for quite a while! But in the time being, I am going to email you Pete for the rest of the information on pots, so I can be well educated when I get to start the set up.
