Sorry about the very long delay in putting this tank together. I've had a lot of things going on in my personal life that have put this on hold. Well, I can't stand it any longer so I'm moving forward. I found a very cool YouTube video that shows the biotope that I'm trying to simulate. I'm going to try and duplicate this environment as best I can. Most of the fish you see in this video are gobies, but you get a good look at the blennies at the end of the video (last minute). It would be very cool to exactly duplicate this with oysters and barnacles, but I don't think that it will be possible. Anyway, enjoy the video. In the mean time I have a lot of work to do to get this project going again...next update will be hopefully in the next month or so, maybe sooner.
