I just noticed these white spots last night. They are only on the backside of my Mopani wood (not facing the light) on the darker colored portion of the wood.
I would say I have almost two dozen spots/specs, they are very small. Should I be alarmed?
Do you have Nerite snails? They look like nerite eggs to me. A bit unsightly but do no harm, they can hatch but not survive in freshwater so don't worry about being overpopulated.
those can be a little hard to scape off.. you may have to take the wood out of water to do that.. even after those are hatched, the shells remain stuck to the wood..
Wow, my snails must really like my tank because the number of eggs on the mopani wood has increased by at least 4x. Not only that I'm seeing them on the glass too!! I'm not liking this.. :yuck:
