, 'snails in my cray tank', 'I''ve noticed that there are two really small snails in my 20 gallon crayfish tank. i believe they came into the tank when i put my hornwort in. Does anybody know how big they will get? I know they may become a snack for my alleni but i''ll take the chance. Also, How long will it take for them to grow to full size. The snails, that is. I do think they are Apple Snails. Thanks for the help.'
'i would be surprised if they make it to adulthood. your cray will probably eventually have them for a snack
'try apple snails and no light accept for natural or room light but not directly on the tank
'when i had a koi tank i got a plant contaminated with those snails. they never get bigger than what you''re seeing right now.... maybe 1/4 inch. i fished them out and put them in their own little container and watched them for a few months. but, your cray will probably eat them before they breed and overrun your aquarium.
