*Blushes and recollects*
This was one of the first few things I asked when joining this site... and someone told me it was a bad sign and nearly caused me a breakdown "Oh... Thanks just got him a few hours ago!"
I don't really think of him talking... Drax in the back of my head it sounds more like a "MEEP! MEEP! MEEP!"
Actually now I remember... I asked about what looked like yawning... someone said this wasn't good but after study *Opening random book* I believe it's actually a Betta's way of sort of cleaning off the Labyrinth Organ.
Just keep in mind... as sort of a common sense thing we open our mouths randomly XD
