I got some new plants the other day and I found this in my fish tank tonight. It's way cool but is it actualy a Limpet? I will take some more pictures next time that I see it.
The Fish Store on Roosevelt. Heres the address: 6109 Roosevelt Way N.E. Phone is 206-522-5259. When you walk into the store walk straight head and the tank is on your left.
I have lots of these in my 75 gallon tanks as well, I didn't know what they were until I read this thread. I thought they were just snails, they don't move very fast and are extremely small. That is probably why my green sunfish doesn't eat them.
