Peanuts- have that site thx. That is where I saw the golden ones that I am interested in.
Lindyloo- they are trumpets I think. Got about 20 off trade me.
Blue and kim- Have two very large ponds outside with a stream and bridge between. Have a photo so will try and put it on here. The snails are for the outside ponds and the ones I am getting have come from outside. Have lots of plants for them plus 4 large goldfish in the bottom pond and an axolotyl in the top. Don't think I'll have a problem with the population getting too big lol.
Thanks for the great advice though everyone. Got my tank today, got it all going and set up. Only problem was got it half filled and we ran out of water. (tank supply) Just my luck!!!
