I've had this one for 2 months now, and it was in qtine for the 1st month. So far it's grown about 1/8th inch around it's circumference. It's very pretty and looks almost as good in person as it does in the pictures. The green eyes are very green and quite cool - I like it!
It's under a mix of 15k & 20k MH light and is about 20" deep in a 36" deep tank, but Im running 250w & 400w lights over the 475, so that's why it's kinda deep.
