Well I have read that they can only be bred in brackish. Well mine are in a heavily planted freashwater, and they started laying eggs. Read this was common and that nothing would come of them, but one by one they started disappearing. Now I have about 5 little snails in my tank, about 1.5-2cm diameter. Look just like mini ones of the zebras, but the stripes are fainter.

I havnt added anything new to the tank for over a month. There are no pest snail eggs that I can find, so I think that I have bred them.

No idea how, I know they are supposed to be gradually taken into full marine as though they were being washed down a river, but meh.

Any opinions?

Edit: They are zebra nerites

Guess no one is bothered.

it might be like mollys, they require brackish water but it isn't necessary, when was the last time you added something to your tank?

before christmas. still no holes in any of my plants, and i have seen at least 6.

couldn't of come on anything, you must of bred them!

cool

Although I have to say, I havnt seen any larger ones at all.

Maybe they die soon after they hatch?

could do ... like you said they need to be taken in to full marine, couldn't you put them in a small breeding tank and put some aquatic salt in

I could but i dont have a hydrometer.

this mght be of some use to you

they are selling those plastic ones on ebay for £10 but it is qutie a lot just for a few snails, you might aswell buy them for that price!

Yup. Hydrometers are £15 each at my lfs. And thats just the cheap, swing arm ones.

i just took piece of wood out, scrubbed all the eggs off, went to dinner... and there's about 10 on there already.

Moved at Esfa's request.

Thanks

I'm hoping Neale will be able to tell me what's going on.

Hey Esfa. I doubt the nerite eggs hatched.
The breeding cycle for nerite snails is very complex and requires 100% brackish water. No chance in freshwater. They'll still lay their eggs, but wont hatch. Anyway that you have added marine salt to your tank?

Well I have a brackish tank, so its possible some could have got in, but it would be like sg 1.00000001

I've heard claims of people breeding nerites in freshwater. Those were Olive nerites though.

I would have thought that nerite eggs probably would hatch in freshwater so long as the conditions were good enough (I guess comparable to where they come from in nature), but that the larvae from the eggs wouldn't be able to live long enough in freshwater to develop into snails?

Really for brackish a hydrometer is the most important tool. Can't keep brackish fish without it. You should just pick one up any way even if your Nerites do'n breed. Mine have never bred. Mine are saltwater ones I collected locally and I keep them at 1.016.

Really... and what sg exactly is 100 percent brackish water? 1.001? 1.010? 1.018?

I dont understand at all what you mean by "100 percent" brackish water, that doesnt make much sense.

Why dont you explain more about the breeding cycle and inform Esfa and the rest of us please since it seems you have knowledge on the subject. Im interested.
