White Cloud Mountain Minnow with red mouth.
Hey guys. It has been about 3 days since I got my 6 White Cloud Mountain Minnows. They all seemed to be doing fine except for one. This one is moving a little slower than the rest it seems to move by jigling and not really how the other fish move. He/she still eats but it's kind of weird it looks like someone put bright red lipstick on the fish?
What is this? What should I do?
