i maybe wrong but i think there is more then one sort of tsn

There are actually several. I don't think the scientists are really sure how many their actually are and if they are subspecies or different species. There is just very little information about them.

I say shoot for a 10-12LX6-8W33-5T. Tallness is not as important as width and length as they are bottom feeders. Filtration has to be crazy strong. Remember a full grown RTC is at least 3-4ft long.
