hi there!
thought i'd comment on these:
i've seen/had a dozen morphs of pink w/ yellow centers. these definitely take the cake! although, these are kinda pink/lavender with yellow/green centers :lol:
that does depend on the lighting though. in my work tank, they are more pink/yellow. in my home tank, more lavender/yellow-green. (same lights, different intensities and tank parameters of course!)
the coloring is just so intense, even under a flash shot:

and i think Mr. Ugly will get my back when i say: yup - they really are that colorful and intense!

(feel free to disagree if ya want Mr. U!

)
they were originally acquired from the now closed "Big Red's Pets" (a local internet outfit a while back) who got them at the wholesaler 'Pacific Aqua Farms' out of LA about 2 years ago or so. i strongly
suspect that they are from Tonga, but don't know so.
at any rate, hope that information helps or at least is interesting!
