Hi Brian,
I don't know how I missed this post. Anyways, I've just noticed that my discus in the picture is actually doing some funky things. I saw, what looks like a breeding tube when he(?) went sideways and did some shaking towards my other discus.
What are some mating rituals for discus??
The two new additions have pretty much taken over the tank. The first 2 discus I got before (the one in my avatar) have been getting picked on lately. The little powder blue one hides all the time now.
I don't think I"m that lucky, but I think the two new additions have actually paired off and the female is chasing the other away.
