Hiya PJ,
We have a
bird wrasse which is a little different but a lot of the info in the
Scott Michael book is the same. The minimum tank size for the Dragon is 70g and the book is pretty much spot on. Also it says he is an aggressive meat eater and should be kept with other aggressive eaters. Our bird wrasse is the most aggressive eater in our tank.
The worrysome line is the part about him eating your clean up crew. Our bird wrasse ate every critter in there including smaller fish.
The last thing is has in common with the bird wrasse is the burying part. Our substrate is spread all over our softies and I have to get out the turkey baster every day to clean up.
This looks like an awesome fish for a decent size tank but once you go the aggresive meat eater route you are stuck with FOWLR which is what my 90g turned into.
