Flasher wrasse coloring
 

Hello,

Our LFS has McCosker's in stock but they are maybe 1.5" at the outset. They aren't fully coloured up yet, and I was curious if they would get to those brilliant colors in captivity if purchased as juvenile. Do you have to get an adult to have that brilliant color?

They usually get all the nice colour once they get older. As far as I know it doesn't have any effect on colour being in captivity or not. As long as they are happy and healthy the colour should come.

I think what you saw are females (or sub-males) McCosker's. Get a couple of them and watch one or both turn into males. :biggrin: Adult males have "brilliant color".
Good luck.

I was debating getting two - either two McCoskers or one McCoskers and one Yellowfin flasher. I can't really decide which is prettier. They are both awesome. Id ideally love two males of different species who flash each other in territorial disputes (without getting aggressive), but I bet two males won't be different than just having the one fish in terms of color and behaviour..

I'm getting it/them after work tonight and putting them into a 14 gal quarantine tank for a week. Again, if this is the wrong thing to do, please let me know. I only have experience with Lyretail Lunars, which are a totally different creature.
