Larval stage for snail ID?

[aquaworld75]

I am seeing hundreds of these accumulating in a tank. At first I thought it was algae but noticed they are moving around .. Anyone can ID? I have a few Stomatella snails. Is this the larval stage? or is this another snail / pest? Thanks!

Those are flatworms (planaria). Good guidance for getting rid of them here:

Red creatures everywhere in fallow tank

Hello there, I have these small red creatures all over my rock and glass in my currently fallow tank. Sorry about the bad lighting, but can anyone help identify and let me know what I should do about them? Thank you!

@shanepike thank you for the info! I guess I’ll be doing a deep cleaning and treatment soon.
