Pest snail population decreasing??

[Sandra the fish rookie]

I know.. weird topic.. but I have a small 2.5 gallon that I use just for my pest snail overflow (AKA Gazoo the pea puffer lunch box). For some reason they are just not populating/breeding in there??? I have a sponge filter, heater and live plants in there.. I do water changes but for some reason they just don't do great in there.. 

What could be the issue?

As a rule, more food equals more snails. Some extra calcium (cuttle bone, etc.) can help also. Put more food into the tank and odds are you'll get more snails. If you go the cuttle bone route, just go to a Walmart and buy some from the pet bird supplies. They're really cheap. They may float around for a bit but will eventually sink. (Eventually being days into weeks.)

The topic isn't that weird.  I'm curious as to where my trumpet snails went.

Like many of us, I decided to accept the bladder and trumpet snails that hitchhiked into my tank. I didn't care much for the bladder snails but watching the trumpet snails tunnel through the gravel was fascinating.  Over time the bladder snail population declined. This was partly because I used them as snacks for the barbs, and partly because the smaller ones seemed to get stuck on the HOB intake.  I recently realized that the bladder snails are back in numbers, but I haven't seen a trumpet snail in weeks.

Would want to see a water test and know the substrate, feeding schedule, lighting ect to help diagnose an issue. Often a photo helps. Personally I've seen improvement in my snail tanks when I have a long light cycle or window sunlight for the plants and algae to grow, feed well, and keep an aragonite substrate or have plenty of crushed coral in the tank.

I've also had the issue recently with my trumpet snails competely dying out in a tank while the ramshorns survived. Still trying to puzzle out what the issue was.
