Thats true puffer how could i not say that I've got a 10gallon purely for snails!! Snails as plecos will need additional feeding though if they run out of algae!! If snails get picked on too much they will become 'nocturnal' active when the rest of the fish are dozing at nightPufferpack said:A single large Apple or Ramshorn snail will do a good job as long as no one in the tank picks on them too much, then they only clean at night.
