I would like to buy a nerite snail, but my LFS only carries Saltwater nerites. Are they different species? can Saltwater nerites be acclimated to FW? if so, how would I go about doing it? and I'm thinking about putting it in with a Betta, anyone know if it would get eaten? I have heard I should feed fresh vegetables and put in calcium supplements, but I have off-the-charts hard water(with LOTS of calcium and iron), would flake food and algae wafer be ok?Thanks in advance, everyone on this forum has been great!
