I got 4 apple snails for £2 today.... It was meant to be 5 but one was empty sell so I let that one go haha. Anyways put them all in my bettas tank. And will be taking two of them with me on Sunday to my main tank. Only one apple snail has got the guts to come out his shell and wonder around. Anyways my betta "Bubbles" keeps biting him (The fleshy bit not the shell) not flaring or showing any signs of hating him just a little nip every now and again... Will this stop and will it hurt the snail ?
