already though pest snails in the aquarium aren’t one of the most serious fish problems that you will confront along your journey, they can become a huge headache if you don’t know how to effectively keep their numbers down as low as possible. Fortunately, there is a really easy to way to get rid of snails in your fish tank set up — all you will need is a piece of lettuce or zucchini!
After you have chosen what kind of vegetable you want to use to get rid of the snails you will need to blanch it. By doing this, you will be accomplishing one of two things – 1) the veggie piece will be soft enough for your fish to eat, and 2) it will sink to the bottom of your fish tank with very little effort. The easiest way to blanch the piece of lettuce or zucchini is to pop it in the microwave for several seconds. Just make sure you use a microwavable safe container!
After the piece of veggie is ready to eat and sink you will then be ready to start getting rid of those snails! In fact, the whole course of action is essentially done once you have thrown the lettuce or the zucchini into the fish tank. You will need to let it sit in your tank long enough for the snails to become attracted to it — this generally does not take more than a few hours.
Once you see a sufficient amount of snails on the piece of veggie that you threw in you can take it out and throw them away. Just remember not to get too excited when you go to pull them out of the tank — fast movements will only shake them off and right back into your gravel.
While this isn’t going to completely get rid of snails in your fish tank set up, it will make it so you barely already notice that they are there. In fact, you may find that instead of viewing them as one of those dreaded fish problems you truly enjoy having a few of the pest snails present to act as an additional clean-up crew for your aquarium. Just remember to use this method at the minimum once or twice per week — any less than that and you won’t be able to keep ahead of your growing snail population!
