I have 10 in a 24" deep tank. Every now and then, I'll see them make their way to the top of the tank and almost jump out and then swim quickly back down. I've never owned these cool little fish, and I gotta admit that its tripping me out.
Is it a sign of stress? Kinda looks like they're taking a gulp or air.
