Can't tell I'd have to go back and look again. But keep feeding those Hikari pellets! That is good stuff, are you feeding Gold or Staple? I feed Gold and these bottom feeder wafers to mine, I keep the schedule irregular too. Let him fast for a bit as well, the colors will improve rapidly if you feed less often. Every once in a while I will throw in a guppy or two.. (Raised in my ten gallon of course, not store bought).
