I have 7 white cloud fry growing out in a 5 gallon bucket. The eggs apparently got siphoned into the bucket when I did a partial water change, and since I was saving the water for the houseplants it didn't get dumped before they hatched. They've grown out quite nicely w/out a filter, just some duckweed and snails. Thing is, the larger ones look white. I figure it's because they're living in a white bucket w/out any substrate aside from a bit of debris that was siphoned out of the tank.
