My catfish yawns a lot and my nitrates are never over 15ppm. They do it to work their jaw muscles
yea a lot of fish do it......i've only seen my clown knife and some of my cichlids do it but i have seen pictures of aros doing it too.................never heard anything about it having to do with high nitrates..........
I have seen my red spot sunfish (north american native) that i keep in a 40 gal heavily planted tank yawn several times, I keep duck weed covering the tank. The back and one side are covered in algae, i read 0 nitrates, 0 ammonia, and 0 nitrites.
Oh i see. Well, the first time I saw my jd do it i was so scared! It was right in my face against the glass and then all of a sudden (O.O)

Another myth BUSTED, if it is nitrites maybe because they are trying to get more water flowing over their gills, but not nitrates.
