Did a water change last night as well as cleaned the glass inside and out. Tonight I get home and find small white, semi-transparent spots on the inside glass. They are around the size of a sesame seed and in random clumps in the 2 front corners and a couple of other spots on the front and rear glass. Could they be from eggs? I have 2 juvenile angels (maybe 2") that seem to be a pair. Wouldnt they be too young to be breeding? The spots dont appear to be raised so im wondering that if they are from eggs, maybe they were eaten leaving these spots behind? Sorry no picture Im terrible with things like that.
