Also, as for live aquaria DD, I have never dealt with a more reputable company. They searched for 6 months and sent me a mature H. trispeculare and no cost because of a labeling error. They called or emailed to give me updates on collection and a manager was always available within hours to answer my concerns. They even called the collection facility in Western Australia, while I waited, for an update.
On several occasions, like this one, they will come up with an incorrect ID, but usually they missed a newely described or rare species to the aquarium trade. Fortunately or unfortunately, I am obcessed with these damn creatures and can note the mistake.
As for tank size. I take their description as being for the specimen sold. 14" coral cat in 180 is OK. If you are waiting for any vendor to describe the detailed husbandry of an animal, you will be old and grey before you feel comfortable with their comprehensive list.
Just my opinion.
