Thanks for the info.Cool, I found someone with a Papi Chulo Frag. A fellow Canadian too!
Not many "Papi Chulo" out there doing a google search. Your thread was a Google Search HIT.
I got one about 8 months ago from Reef Raft Canada here in Toronto and it lost it's TWO-TONE Coloration after couple of months.
I ignored the change since it was healthy and the PE was Strong/Red with White whiskers.
Then when I lowered Phosphates, and got them stable. It really colored up, and growth took off too. I actually stopped Aminos totally, and Colors kept getting better.
The reason for looking for other people with Papi Frags. Is to compare Color/Growth Rate.
Yours has encrusted nicely.
Take care of it, and wait patiently, it's my most colorful RED PE and hardy SPS (Since I really beat up The other Frags (P swings), but the Papi was forgiving and a quick healer)
It was the first time i saw this on fragbox (maybe one more since) and the piece looked healthy.
Not sure for the two-tone coloration you speak about, mine seem to be consistent red for now.
I will go to see your thread for pics of it.
I did not know reef raft had a store in Toronto.
