"Do you know how to tell the difference between a juvenile Queen angel, and a juvenile Blue angel? "
The price tag
"Does anyone have any experience with these fishes and if so, tell me about them."
They need a large tank 180gal or bigger, bigger is better. They grow to 18" length, they need sponge in there diet, plus everything else; they don’t tolerate other large angles and they should be the last fish added to your tank.
Maybe more will chime in with there two cents. Always wanted one but only have a 135gal. tank.
