Flag Tail (Fei Feng) question?

  • We are currently upgrading MFK. thanks! -neo
My flagtail does this and i've had him for a few years, nothing too stress about.
 
My 13 inch flagtail would do this when eating flake or pelllet,but only when food was present. I had him for 7 years until I traded him like a fool.
 
It's a 5 year-old thread
 
Yes mine too gasp at the water surface and also spits out bubble and my water at the top side tank create bubbles at the side. Before i hav this fish there no bubbles at side. If the bubbles of the side tank cause by them is the water condition would be fine?
