I was just give two of these little guys i put one in each of my tanks. The person who gave them to me saod when asked they are baby golden apple snails. Not sure if it was a good idea to take them in but i did. ...hope they live
Maybe. I have a lot of algae and snail jello in there all the time for mine so if they do eat some, I know that the salvinia/duckweed replenishes itself faster than being eaten. Try growing some spare in a little container.
