Quoyi parrotfish reef safe?

Beautiful specimen, but I thought males had more red on them? Mine has a significant amount of blue as well. I'm not convinced this is a Quoyi. Anyone else have any thoughts?

The above picture looks like Scarus Rivulatus to me.

Love the maculiceps in the pic too
 
I'm starting to lean toward female rivulatus. Here are a couple more pics, there is a slight hint of orange in one.

Pretty blurry, but might see orange?




 
OK, so somebody help me. What phases do they go through? Are the males different from the females, do they go through all the phases eventually or do they stop at a given phase? Please educate me. :)
Ok, this is my general understanding of parrot and wrasse phases:

In a group, there is one terminal phase male, several females, and initial phase males. If the terminal phase male dies, one of the females transitions to male and becomes terminal. Initial phase males do not transition to terminal phase. The transition from female to terminal male is permanent (hence the word "terminal").
 
If the terminal phase male dies, one of the females transitions to male and becomes terminal. Initial phase males do not transition to terminal phase.

That part I didn't know... why wouldn't the initial phase male just "finish off" the transition?
 
Most species of labroids are protogynous and sexually dichromatic, with at least 2 color morphs — a usually drab-colored ‘initial phase’ (IP, either female or female and precocious male), and a brighter-colored ‘terminal phase’ (TP) male (Robertson & Warner 1978, Warner & Robertson 1978).

In some lineages of protogynous fishes, 2 types of males occur: in some groups males are monandric (all derived from sex-changed females), whereas in other groups (like most scarinine parrot-fishes of the genera Scarus and Chlorurus : Robertson et al. 1982), males are diandric, i.e. derived from either undifferentiated juveniles or from sex-changed females.

With few exceptions, changes in coloration and sex are synchronous in scarids (Choat & Robertson 1975, Bruce 1980); less is known about sex and color change syn-chronicity in labrids (Warner & Robertson 1978, Moyer 1991)

Thank you for the schooling on this subject!
 
Scarus iserti is reef safe as well. Looks almost identical to the Princess, with differences on the margins of the caudal fin being the easiest way to distinguish.
 
Most books and other resources say not to try and keep parrots at all, why is this? If I can buy a shark egg for 50$ that will grow into a 3.5-5ft monster then what would make a parrotfish harder to properly house and feed?
 
I agree. Think those books are referring to the larger parrots that actually eat rock, coral, and algae and excrete sand? Like the pic SDGuy posted earlier with the hump head. I can definitely see those being discouraged, but not the Scarus species.

I also think that the food consumption of parrots is what scares people. As sad as it is, most "difficult" fish are only labelled as such because they require a little extra food a couple times a day and maintaining good water quality.
 
Yeah, many parrots get beastly large, which is why I never even considered buying one (ie the most popular for many years being the bicolor parrot). But a little more research revealed that there are a few good options for large aquariums.

They wouldn't be the first group of fish that have been unfairly labeled as unkeepable.

Dunno. They are rather easy to feed. Much like tangs, they just try to nibble on everything after a while. Pellets and algae tabs are taken with gusto. It's pretty simple to feed this stuff automatically several times a day.
 
Not really.... often even common parrots won't feed in captivity. Mine was eating at the LFS... the next one that came in did not.

So your experience with one fish that just arrived at a LFS leads you to conclude this? :strange:

They are grazers, just like rabbits and tangs. It is really not difficult to get many species to start nibbling on stuff. Certainly much easier to get eating than some angelfish can be. The stigma in the hobby of parrots in general is based on an incomplete understanding of the different genera that make up the family. Obviously the big 4' bruisers are problematic, but there are smaller species that do fine.
