Signs?

[gex18]

I noticed strange behaviour between 2 of my discus in the last 24 hours, their top fins seem to twitch, and they only do it to one another, also i noticed (when lights were off) the pigeon blood would approach the blue turq from below (almost vertical) and swim up alomgside it? It seems weird to me, also after i fed them tonight, they seem to wag their fins at each other and stay in one corner of the tank, however the pigeon blood stays there ALL the time now but the blue turq swims around occasionaly, are they not menat to stay there all the time? Oh yeah the pigeon blood and the biggest discus in the tank really are nasty to each other now, last time i checked they were mouth fighting!

Have the two discus started cleaning any surfaces?

As for the mouth locking, you have some fighting going on in the tank
