Man if there is something that bugs me it is pests in the aquariums. these are the pests that i have been sadly familiarized with.

The Annoying!
These snails are the only and most annoying pests ive encountered so far.
Facts: May in the begininng seem harmless. But later on you will change your mind. you may think that one or two are not so bad but ooooooh are you ever wrong. Those things multiply like crazy. If you spot one or any kill it immediatly, try to remove any slime blob with spots as soon as possible. because thats their eggs. ok they do no damage to the inhabitants in the aquarium. actully its the other way around, they take care of algee and uneaten food. at one small price wich is what makes them pests and can be described with one single word: INVASION!. They are almost impossible to get rid of. There are only three way i know of. 1. get a snail eating fish 2. Boild them in the aquarium(remove fish and plants first) 3. Put copper into the tank(Remove fish first)
