G'day

Here's a pic of my A. cacatuoides "Orange Flash". Just today, it has been acting as the king of the aquarium, swimming around until just a couple of hours ago, when I noticed it was looking miserable and hiding - with redness on its face, a slight red tint on its body and breathing rather heavily.

The female is currently in spawning mode.

Any ideas what this is? I'd like to take some corrective action if the problem is identified soon enough - Apistos don't seem to last very long once it is sick!

Thanks
