I got a few of them back in the summer before MACNA. They went into the tank and vanished. Then about 2 weeks ago one of them showed up in the tank looking good and fat. He was visible for about 4 days, I got some photos of him to show off and then he vanished.
My tank is 400g with over 120 fish and over 1000lbs of rock. So while not the ideal situation to keep track of little fish like this, I am a sucker for a little fish and can't say no.
