RAMSHORN SNAIL "BLUE"

 The Ramshorn snail is very popular in the aquarium trade and like most other snails it is easily transferred into aquariums when buying live plants. There are different varieties of these snails available in the hobby with the blue, pink and red varieties rather attractive. Care should be taken not to over feed the tank as this is the main cause for them multiplying and populations getting out of hand. Snail killers should be avoided unless all other options have been exhausted first.
