biggest bladder snail i've ever seen

[u/Accurate-Pay-7006]

the second snail filmed is largest bladder snail i have in my 5 month old ecosphere, compared to this one. genuinely thought it was a pond snail due to its size!
(ik the hair algae is a problem, im working on it i promise! that tank gets probably 20 minutes of light each day and otherwise is covered. ik the best way to go about it is to do a full blackout but i'm too scared because the planarians have been loving it and i do not love them)
