a few years ago i brought back some snails from port A thinking WOW look at all these snails and i'm paying 2.50 each at the lfs. well i put them in my tank and thought all right got a 100.00 worth of snails for nothing. next day i see the new snails and my old turbos shell to shell. wow! are they matting? NO THE NEW SNAILS WERE EATING MY TURBOS. no no no i said and started pulling out the snails. i think i lost about 10 turbos and all the carniverise snails. it's not that i saved a 100.00 but lost 25.00 of good turbos. just a thought. next time i bring something from the coast i'll put it in other tank cause you can bring back a lot of neat stuff.
