Does anyone else...

have their d.gourami or any fish eating their CO2 bubbles?!

Mine seems to have taken a liking to it...I've never seen any of my fish do this besides this guy..

that's a new one for me. I have LOTS of CO2 bubbles in all of my tanks and I have never seen any fish take interest in them.

I thought it was odd too. I mean, my poor plants get nothing and this fish gets everything. Doesn't seem fair to me.
But seriously...this guy will take a minute out of his swimming time just to sit at the ladder and pick at all the bubbles. It's quite interesting to watch him.

...You'd think I never feed him!

Maybe it's some kind of odd bubble-nest related thing. Perhaps he thinks they're bubbles from another male. I haven't heard of this before.

Maybe the carbonation eases an upset tummy ... I know it does it for me
