wasn't Pat (Comatose) on the verge of getting some of those shortly after acquiring his E. anatina? haven't seen him on here in ages, but he might have some useful info in that regard.
Myth... there is no reason any fish should not reach its full aquarium size if properly cared and housed for. If you think they grow to the size of the tank, read the sticky about it. Stunting growth of fish to make them stay in a tank that is too small is very unhealthy for the fish and cruel on your part.
I can say first hand, a tesselata will not live for life in a 100gal.
