Thanks for all the comments. Heart & Sole is right...I think the brain is a lobophyllia (green lobo).
The HOB fuge is a life saver...it's awesome. A lot better than none I guess...
Yes, that is a canary blenny. I have had it for 7 months, up until about a month ago, it never ate anything I fed the tank. It still barely eats flake and frozen food. He's a little hunter, venomous too!
The xenia field...if they made a "weed and feed" type of product to get rid of the xenias, I'd buy it! I compare them to the dandelions you get in your back yard. I frag them out and get a little credit, so I guess I shoudn't complain.
Thanks again guys!
