X200. I had a malabaricus and it was out and about all the time. As big of a wet pet as all the cichlids listed and more of a predator. Anytime I opened the hood he swam right to the top.
Not sure where in Delaware you are, but That Pet Place in Lancaster has RTM in stock. I live in West Chester and I have a 4-4.5" RTM that I could be talked into parting with. PM me if you're interested.
