Betta making noise?

[Misakitty]

This has been going on for a few weeks now, and I can't seem to find anyone else mentioning this.

My male betta occasionally makes a weird mouth motion, and I hear a 'clinking' sound. I didn't think they made noise, and I certainly didn't expect to hear a noise from inside the water (he's not at the surface when he does this). He's not tapping on the glass either. Is this normal?

Sounds like you might be hearing his teeth..?

[Misakitty]

He kind of jerks the top of his mouth back, almost like he's trying to open his mouth with taffy in it, and then the sound happens. It's bizarre lol, and he only does it maybe once every other day.

I don't know much about the physical properties of water and sounds in it; could the water be amplifying the sound of him clicking his teeth?

[Arashi Takamine]

Probably and you probably got great hearing too. I can sometimes hear my fish chewing his pellets or his little heart beating but that's if it's quiet enough.

Yes, the water amplifies it. I often hear this sound. Not sure what causes it but it's most likely his teeth. Nothing to worry about :) Sounds pretty cool though

[Misakitty]

Thanks for the info, I was a little freaked out the first few times it happened when I saw he wasn't tapping on the glass.

Nope, it's all good, we may never know what it is, but it's not bad, just funny :P

Do you have him in something spherical? Because when my betta eats his food it's amplified so much it sounds like great mandibles of death out to destroy :P

[Misakitty]

It is round but not spherical. It doesn't happen at feeding time, but he may just be clicking his teeth as a threat to me. He's pretty vicious :P
