I have 4 of these guys, 2 each in different tanks. I rarely see them, but whn I do, it's a treat! One in my guppy tank comes out every evening when I feed the guppies and eats the falling food, and one in the ciommunity tank does the same. The second one in the community tank has wedged himself between some rocks and you have to look really hard to find him, but he's there.
They are absolutely beautiful fish, I wish they wouldn't hide
