Zebra snails stocking

    Hi, I'm confused about zebra snails.
    I've got about a month old 125l (33 galons) tank and lots of algae. I'm not sure if they are caused by LFS water that I added with fish or from fertiliser. I added both at roughly the same time so I don't know what's the cause. Anyway, I want to get rid of them.
    In the store they say that zebra snails Neritina natalensis are the best. What I'm not sure is stocking. In the shop they say only 1 snail per 50l (15gal?), on websites I read things like 1 per 5 gal, someone has 8 of them in 33 gal.
    On the shop site they say they only eat algae and refuse all other food so I'm afraid if I buy too many they will die of hunger but if I buy few they won't eat enough algae?
    I would like to get the right amount straight away because there are no snails locally, I must order them online and shipping is 3x more expensive than snails.
    Thank you for advice.

    What kind of algae do you have? Nerite snails don't eat every single kind. They only eat brown algae (diatoms) I believe. Further, they won't get rid of your algae, they can only help a little. I would look into the cause of your algae and try to fix it there though it wouldn't have been caused by the LFS water (which you shouldn't have added to your tank).

    That said, you could probably add 5 or 6.

    Here's a thread that should help:

    Thank you :) I'll read that and try to see what the cause is

    You might try cutting back the number of hours that the tank light is on. How many hours a day are the lights on and is it in front of a sunny window. Nerites will also graze on fresh veggies like zucchini squash. They also eat the green algeas. You would be fine with 4 to 6 zebra nerite snails. ..:;hi1 Alison

    The lights are on 8 hours a day, in the morning and evening, with break during the noon.

    Algae aside, they are good at helping to clean and fun additions to a tank if you do decide to get some. I personally have 3 in one 10 and 2 in another. They may eat supplemental food. Mine finally started after about 6 months of cleaning the tank, and seem to really like spinach, green beans, and snail jello. They now eat like my mysteries.

    Nerites are very low on the bio-load, so I think 4-5 would be fine for your tank without any problem. Could probably even do a few more if you really wanted to...

    Thank you, I ordered 4 of them. We'll see how it goes.
