My new fish

[Nihoa]

a yellow watchman that we bought arrived to us green but after a week of feeding heavy he is already starting to yellow back up. there is always individual variation in colour/pattern but, at least in birds, it relates heavily to condition. thats the whole point. brilliant colour shows a potential mate that an animal is able to secure more resources than needed to simply survive but also to invest in these displays. a measure of fitness and a means for selection.

i dont know how fish work but with what we are seeing in our watchman maybe your fish will brighten up too in a happy home with lots of grub.
