Greetings all 
For 2 weeks now my 55g planted has been overun by snails that I probably picked up on some plants I bought. I did not know about soaking them first, (and this was from a very reputable firm) After picking them out I purchased 3 assassin snails. They are tiny and I put them in my tank but today they seem to have completely disappeared :uhoh:. The others are thriving... Is this normal? Appreciate the info/experience as I'm a bit worried...
