[Thanks Amanda. That's exactly the information I was looking for. If Queen conch is going to get huge, I'll just get fighting conch. I dont' want anything that climb on rock, knock over coral etc. That's why I get rid of my pencil urchin - plus it was eating all the purple algae.
I haven't been to the local fish stores lately, except we just visited Fish Paradise in Ft. Worth on the way back from visiting Marc and his two tanks. I don't recall seeing any conch for sale. But I'll keep looking for them locally or join a group order.]
