I recently bought a veiltail betta fish for the first time and eveything's been going fine, but... A few days ago he started burping up bubbles and the bubbles collect at the top of his bowl and never pop. Now at first that didn't worry me too much, but the other day I came home and there was a whole bunch of them collected all around the bowl, like over a thousand. Is there something wrong with him or do they just do that?



Sounds like he has quite the impressive bubble nest though.
