So i was doing my monthly changings, gravel vacuumed and change 10% of the water, i also changed the filter pads and added a plant background. when i stepped back i saw my three spot gourami with some WEIRD colors! the white/silvery dots on his fins where very bright and he had no spots at all, instead he looked like an opaline gourami! very dark vibrant vertical stripes that were scwiggly, i was wondering what this was?? dont worry he turned back to a three spot right before i came up here to post this. any ideas?
