some hate 'em, some like 'em
I've always had snails in my tanks, whether I wanted them or not. I'm not so fond of pond snails and I just found some in my new tanks. I'm hoping the ramshorns and MTS will out compete them, or eat their eggs or muscle them out. I've noticed before that each tank tends to have a dominant snail species, so I think some kind of snail war might go on. Does anyone know about this?
The only snails I've intentionally added were Malaysian trumpet snails. I use fine sand substrate and they prevent compaction. I've had one problem with them: the tip of their shells tends to grow BBA, then they crawl all over the tank spreading it! It looks kind of pretty though, but I feel sorry for the snails dragging that "cape" behind them through the sand. Sometimes I pick it off.
I wonder, do ottos eat snail eggs?
