Hello I found these on one of my aquarium leaves anyone know what they are?
Look like bladder snails, perfectly harmless but often seen as pests due to them being so prolific.
Agree with @Demeter, bladder snails.
Thanks for the replays should i kill them or let them live?
I think they're cute, but I know others see them as pests. I just think of them as a free clean up crew. I haven't seen them hurting my plants at all, just eating the algae
They're completely harmless and feed on algae and uneaten food. However, they reproduce very quickly when enough food is available. Completely up to you if you want them or not; I purposefully introduced "pest snails" into my tanks because I like them.
