Why are all my snails dying???
I have a 3-gallon JBJ Picotope at work where I keep a bunch of low light plants and a single betta. The tank began to get algae here and there, as well as other muck from uneaten food, the occasional dead leaf, etc. I figured that in addition to my regular water changes, I would unleash a cleaning crew of pest snails from my 20-gallon planted tank at home to help with the problem. I gathered up an assortment of snails from home, including some Malaysian trumpet snails, some ramshorn snails, and a few common pond snails.
The snails thrived for a few weeks in the little tank and cleaned up every inch of algae, ate any food the betta missed, kept the glass spotless, etc. I noticed that none of them were laying eggs, though, and they slowly began dying off (even the younger ones). As of today, all of the ramshorn and pond snails have died, and I have no idea on the MTS as they stay buried in the substrate (Eco-Complete) during the day. The algae has also begun to come back now that there is nobody around to eat it.
My question now is... why in the hell are they all dying? I've kept aquariums for decades and have never had a problem keeping snails alive (of all things). It makes you feel like a real loser when you can't maintain your pond snail population! What could be the the problem? Is the water too cool (78-degrees)? Is the betta killing them (I've never seen him attack one)? Did they run out of food?
Any advice is most-appreciated!
