ok so about the baby snails. they couldn't go in the 10g or the 2.5g because they would get lost in either one. remember these guys are 1mm- 2mm so they would get lost or vacuumed up or lost b/c of the strainer. if you bring over a betta container or a betta bowl etc i can get some loose algae like i've got with mine. cause of the loose algae, ther has been some growing. and also note
