Urchin with pituitary problem

[Nitrate]

This guy is growing like a weed, hes probably tripled in size in just a couple of months. Since he was such a runt when I bought him the LFS gave me $5 off, now hes bigger than anything the LFS sells.

How fast do they grow in an aquarium, and how big will he get in a 150 with 180lbs LR?

Im thinking about naming him Andre.

Plus, they will eventually graze all the coralline algae off your live rock.
