Aquaria: Controlling Pond Snails.

My aquarium cam set up. Gotta love Coca-Cola Products! (This could NEVER work with Pepsi!)
;o)

So I moved the 55 gallon aquarium this weekend. I think the only casualty was one of my assassin snails. He was looking a little bit feeble. I think he got beat up little bit by some rocks being scooped out.

How to control an infestation of Pond Snails:
This is my remaining assassin snail. They have become my favorite part of my aquarium. When I got this one, he was half the size. In my 55 gal aquarium, I try to keep at least 2-3 assassin snails going to keep the pond snail population at bay. Pond snails often come in to your system with new fish or live plants purchased at a pet store. Once you have them, you really can't rid yourself of them. Chemical treatments harm the fish and the only other way I know of is for you to break down the entire system - completely new filter, new rocks, new plants, new furniture and disinfect the glass tank. Frankly, buying some assassin snails is a lot cheaper, less hassle, and kind of entertaining.

Assassin snails don't reproduce like pondies do, so you don't have to worry about THEM growing unconctrollably. They are able to overtake a pondie, flip it over with that big foot and suck the pondie right out of it's shell! Assassins don't need to molt their shells and get a new one, instead they grow larger patches on their shells, which is kinda cool to watch in process.

Drawbacks: Empty pondie shells seem to contribute to a need for more frequent, thorough cleanings of your aquarium because of the decomposition/ammonia releases. I was cleaning my filter and doing a 10-25 % water change every 2 weeks. Since the pondies have come (and are now being killed) I think I need to bump up the gravel vacuum and 10% water change to once a week. Still watching that one.
Also, if you DO have to break down your aquarium for any reason (like I just did in order to move the thing) it is easy to injure, kill (or lose) your assassin snails. So take extra care, maybe to gently remove them first and put them in a bowl of their own water.

Summary: I LOVE my assassin snails! In retrospect, i am kinda glad the stupid pond snail infestation occurred, because now I have a REALLY cool critter(s) to watch.
