fugupuff;2887200; said:that is a good theory as well. I have some photos of h. vittatus spawning in private aquaria in Japan, and they did not change colours, of course goliath could be different.
Like you say, the hobby is only interesting if there are fish out there that can capture not only our interest but imagination as well. The one day there are no longer fish left to find, no more that captures our imagination, is the day I'll stop keeping fish.
fugupuff, can you post the pics? Or do you already have them posted in an old thread. i'd love to see them,...............
