Discu Looks Like Its Sticking A Tonque Out.

[sparts]

Hahahahaha seems funny but i have not seen this b4 some times 2 of my discus at differant times i might add, look like they are opening there mouths wide and it looks like it shows a lot of the inside of the mouth looks like they are trying to put the inside of the lip outside so to speak they do this about 8 times then stop it almost looks like they are sticking there tongues out if they had any that is, any one know what they are actually doing.

I have a discus that actually makes noises.
By the way all my discus are up for sale, pick up only Leeds, they are nice ones too.

Could be lack of oxygen.Trying to gasp for air,try putting an air diffusing thing(lol i've forgot the name)powerd by an air pump & see if this makes a difference.Could just be yawning,not sure about 8 times in a row though,my fish sometimes do this in the morning lol .They have a good stretch!
