augh!! i had a major pond snail problem... their eggs look clear with little white spots all over them... they're jellyish... i THOUGHT i finally got rid of them... but yesterday I saw a little snail... ARGH! I would get rid of the snails right now to avoid the infestation problem... i started out with ONE pond snail.. I plucked over 50 out of the tank by hand when i was totally cleaning out the tank!!!!
