The term “blue rim” is mostly used to describe white and blue marble fish what have the blue “rim” outline on their caudal. I’m using it on this guy because it is spot-on, look at that pretty blue border on his fins!
If someone doesn’t claim him within a few days, I’m keeping him.
This male is a beautiful import who I have put through a quarantine in my fish room.
