The white spots look just like normal raised areas of bumps that i have seen on lots of motoros.
it would not hurt to give your substrate a clean as an outside chance it could be high levels of bacground bacteria in the gravel.
it is not heater burn but!

Thanks DB Junkie,
I have two 250W heaters that are not guarded. I don't think it gets that hot though, but who knows. No snails or anything besides a black arowana.
get those heaters covered NOW!!!!!!!!! ask any of the people on here how horrible heater burns are on a ray. they might not feel hot to you but they WILL BURN YOUR RAY.
