I have a bunch of clusters of these tiny snail like things on my glass. I just noticed them today. I haven’t added anything at all to my tank in several months and I already have 2 stoma snails in my tank. Are they baby stoma snails or potentially something else? Thank you!
These are flatworms probably from the genus Convolutriloba.
They are generally harmless (unless the population explodes) and can be controlled through nutrient management.
You can read more about it here.
Looks like those ghost flatworms that are found in newer tanks without six line wrasse or choris wrasse to eatem. The redder ones with 3 pronged tail are the acropora eating variety which are bad
