I ordered two rice fish (Oryzias woworae) and they each have white spots that are not ich. The spots look a bit too large for ich,(although still small of course) for one thing. For another thing, there are only two spots on each fish. I have not run across this before. The spots are almost silver-ish. The fish are active and otherwise healthy. I have raised the temp to 30C and will keep it there two weeks in case it is in fact ich. They've had the spots for a week, (since a few days after I got the fish) and they have not increased. I can't add salt to the tank as it contains a GBR. Anyone have any ideas?
