I've had my hatian pink tip for almost 2 yrs. in my 90. It moved around alot in the beginning but once it found the right spot, it hadn't moved in about a year. I feed it every other day to every 3 days by hand with shrimp or squid. It is now about 7-8" across and about the same in height at full extension. Mine is actually getting more tan with a green hue but you can still see the pink tips.
