tommy108,
I agree, that is a young rhomboid and likely a female. However, if it were a young male, you will have some slight fading in color when they are brought in from the wild and there is no other rhomboids to display for in the tank it resides. This occurs with the Pyle's as well (Very similar looking fish). It's not a huge color change, like say a Scott's losing the pink magenta spot in the center of the body and turning a dark midnight blue. But some slight fading will occur. The yellow will become lighter.
I'd consider the rhomboids, pyles, lineatus and labouts as slight faders without mates.
I'd consider Scott's, Exquisites, Solars, Punctatus, as definite strong faders of colors. (Most of the fairy wrasses that have blue, turqouise, brown, green, or dark purple as their PRIMARY body color, are strong color loss candidates)
I'd consider any of the orange, hot pink or red fairies as great color retainers with just about no color loss regardless of wether they have a mate or not. That would include:
Flame, Johnsoni, Yellowfin, Social, Conde....just to name a few.
(One fairy to add to this list allthough it is not red is the Orangeback.....great color retainer!)
