I think ORA does a captive bred blue assessor. Kind of pricey I believe but always better to get captive bred.
If you're wondering about the mandarin, you should definitely wait. You could do a scooter which are significantly less demanding to feed if you wanted to keep a dragonet. I have a male and three females. They dance and spawn nightly which is neat-o!
I've had two tailspots. First one starved during a black out I did to starve some hair algae. It also killed the film algae and I had no idea the blenny was so dependent on that. It ate all prepared foods well but when I turned the lights back on after several days, it was really emaciated and died soon after. :sad1:
I would not think of a tailspot or any blenny in that genus as part of your clean up crew per se. They will snack on film algae on your glass and rocks. They will not eat filamentous algae ime. I have seen mine nip some clove polyps right next to its favorite hole but I believe it was just keeping its house clear, not eating them. I've never seen it nip lps or nems, shrooms, etc. I'd say it's a very low risk reef resident over-all. And a beautiful and personable little fish.
If you haven't seen it yet, your Rainford's will sift sand. But not so much as to make a major mess. I do have to blow off my lps on the sandbed every so often. The location of the sifting moves around the tank and is pretty random. You will notice its effects though. I think it's such a cool behavior, it's well worth the little mess.
Carnation is about 20 miles east of Seattle in the Snoqualmie Valley.
Cheers.
