Kissing sounds coming from my tank, not a mer-person

[FishBliss]

So I'm sitting here just now -- the filters are off in the tanks so I could feed everybody and I'm surfing the internet while I wait for all the food to be eaten before I turn the current back on.

I hear smacking, sucking, "kissy" sounds coming from one of the tanks. Loud!

I look up to see why the water is sucking back into the hoses of the filter (because that is the only thing I can imagine that would make such a loud sound).

I see a cory up at the top, at the waterline, making smacking kissy sounds. About 20 smacks. It sounded a little like that nibbling sound that the tiger barbs make when they snatch the floating food from the water surface -- only really loud!

He swam back down, went back up and did it again two more times! And after that he joined the rest of his crew down at the bottom in the sand.

I know they goof around and sometimes they shoot straight up and hit the lid before they go back down and sometimes the go up and down the glass sides. But in several years of having cories I've never seen/heard this.

Have you?

Not corys per say but my blood parrots do it all the time.

I have various noisy eaters including corys that ate floating foods against the glass

I have some Oscars, giant danios and plecos that are very noisy eaters. It's kind of funny because it is something that you never consider as being possible. I leave my filters on during feeding and you can still hear faint crunching and other noises above the filter noise when eating pellets.

Cories are a blast to watch with their antics and especially so when trying to mate.

You should hear all the noise when I drop NLS pellets into the tanks that house dozens of 2" cutteri juvies.

My angelfish make smacking/popping sounds like that. Doesn't seem to be when they're eating though--food is out in the "open" away from the tank walls, and they make the s/p noises up against the walls. Usually in corners it seems.

This has caused me to wonder if angels are related to archerfish, although these don't seem to be actually spitting water up out of the surface but rather a mouthful of air. If I were not a lazy schlub I would research this.
