well, imo the one up front looks like woodstock ( snoopy's friend).
i do have one of my own that had black on him as well, the black is now gone, most the people i talk to say the black does goes away as they get older, mine went away in less than a month.
alot of people do not like parrot fish for the fact that they are hybrids and there mouths do not close and do tend to have issues, and 99% of the time they have been color injected/hormone injected and never stay the color you purchased them at.
but i think they are cute.
but hey thats all my opinion.
I have to disagree with the word 'hideous'. Beauty is in the eye of the beholder! I know they are hybrids and I don't condon that breeding practice but I don't think they are hideous at all. Certainly not hideous in their behavior! One thing is for sure - you'll not have to worry about what to do with a bunch of fry!
