Now that I have started to cool down all the Gymnogeophagus tanks I thought I would post a few pics to show what happens to their color when they cool down. I started to cool them down on Oct. 19th so it has been a little over a month now. Their tanks were around 78 degrees before and are now sitting around 69-70. I need it to get colder outside but we have had an awesome November so far with the temps only getting down to around -5*c at night. So until it gets colder the tanks probably won't drop too much more, I am hoping to get them down to 60 degrees this winter. On to the pics, the before pics will be in warm water and the now pics will be in the cooler water. Sorry for the dirty glass on the new pics, I was going to clean the glass, it seems I forgot. Before pics of Gymnogeophagus cf. Gymnogenys. And after pics of the same fish. As you can see he has lost most of his color, and his small "hump" he had going. Before pics of Gymnogeophagus Australis. After pics of same fish. He too has lost lots of color.
