That is a wet spot tropical fish bag..... lol! I get those all the time as they are in my town. Great Lei! They're in a couple lfs in my NW area now. Got a friend who bought one there at the same size as a walk in. Good luck on growing this puppy out!
Mine is constantly on the move. He is in a tank with swordtails and 2-3" clown loaches, so there is constant movement. He tends to cruise at the back of the tank most of the time, but always moving. He still doesn't relate me to food till my fingers go in.
I beleive you just answered your own question. I am guessing it feels intimidated by all of the other aros that are different species. Are they all close in size? Does the lei get bullied at all?
