That's wonderful news! I am so happy to see little worlds of life develop and thrive.

We have had some warm weather over here in the UK and my tanks are sat at 27deg C The shrimp and snails seem ok though. Here are 2 photos showing some zebra nerite eggs and a close up of one of the snails

The eggs are very tiny. If there is a male in the tank, would there be a chance that the eggs would hatch in the brackish water ?I had an online friend from the United Kingdom, and she told me that many people do not have air conditioning.

There is a chance they may hatch in a home tank setup but there are a few things you can do to maximise the hatch rate, I will try and find some info i squirreled away about it

Yah we don't have air con in the UK, it's killer lol.

Oh, thanks. I do hope that it does become too hot.or too often.

Extract, cleaned up.

Unlike other snails Nerites are not Hermaphrodite, they are male and female, it is impossible to sex them so a group will be necessary to breed them successfully. Nerite snails will happily lay eggs and the eggs will hatch in fresh water but, and here is the problem, the hatchlings will not survive as they need brackish water at the least, preferably marine conditions to survive the early stages of their life.

If you would like to successfully breed Nerite snails here is what you should do, put a group of snails (8 is a good amount) into a small brackish setup and give them a small piece of bogwood as this is the preferred place for them to lay their eggs and is easy for you to move the wood with the eggs attached into another tank when needed. Once the eggs are laid it can take anything from 2 days to 1 month for them to hatch and at this point I must give you 2 options.

(1) Leave them alone and maybe 20% will survive,
or
(2) Move them to a full marine setup and up to 80% should survive.

Either way you need to leave them until their shells become shiny (crushed coral in the tank will give them the calcium they need to develop healthy shells quickly). Once their shells are shiny they can then be re acclimatised to freshwater and grown on using algae wafers to supplement any lack of natural algae in the aquarium. 79 degrees F (25.5 deg C) is the optimum temp for them to reproduce.

There's a lot to if babies are desired!

Purchased 4 more zebra nerites today from a local store, hope they survive the brackish water, they were in a tropical fresh water tank in the store.

That's great! I hope so, too. They are such cute little things, and so useful, too!

Its been 24 hours since i introduced the new zebra nerites to brackish water and they are all still alive, hopefully i will be lucky and have 100% survival rate. I will leave them in the small tank for a few more days then move them to my big shrimp tank [#03] to help kill off the algae.

The lady in the shop asked me if they were going in a tank with a filter and pump to which i said 'no' and i was told i couldn't buy them lol, i said oh well in that case i will put them in my tropical tank where i do have a filter etc, so she sold them me, they have your tanks and details on file so after checking that i did indeed have a tropical tank i walked out with them. Not all tank life need a filter!!!!!
