Another annoying ID...

[gflat65]

I've had this one for a while and it has started to take form (almost table like...). Any ideas?

Not that color has anything to do with it, but this guy is bright yellow/chartreuse.

Here is a shot of it when I got it.

I would say something along the lines of a tenuis. Perhaps A. selago or A. pulchra?

 

[ClownReef®]

IMO A. rosaria..

How old is it?

 

[gflat65]

I've had it for almost exactly 2 years.
