new snail tank!

got my new briggs tank up and running and it is about 10 days old now- white, blue, brown, black, and 2 magentas- they are so much fun to watch! Thanks to all who gave me info on getting the tank started-If I can I will post pics- I rigged up a rock tower to the filter so it's not so noisy pouring into the tank(it's a hob and with a couple inches at the top it sounds like niagra falls-without the rocks there-) the snails seem happy and active and eating!

phooey I am so sorry! my camera's on the fritz but I will post pics soon- Today I actually received 3 large(I didn't know they were so large when I ordered them) light yellow snails- one is near golf ball size! They are all three happily munching on lettuce -but are these regular briggs? I am secretly wondering if they are the kind of apple snails that get REALLY big- and will they mess with my beautiful marble sized snails? also- they keep reaching their syphons waaaaayyyyyy out even though they are under water- I brought them up to the surface and they all "reached" and breathed- but have since been back down and they still keep reaching-my other snails only do this when they climb the sides or rocks to the surface....just wondering...

I guess I am wondering if the new guys are pomacea canaliculata rather than the bridgesii-and if so will they hurt my bridgesii......
k, that's all- I"m REALLY gonna try to get pics tomorrow.
