Well, this is not correct! What you see and think are nerite eggs are actually capsules with dozens of little eggs in it! After hatching, we have a release of veliger in the water. They are very tiny at this stage.

Of course they are! To induce hatching of these larvae, biologists decreased salinity from 15 to The capsules opened 24 or 48 h after this salinity change releasing the veligers. There were differences in the duration of embryonic and larval stages between the two salinities. Here comes yet another problem with Nerite snails. Although all species of the family Neritidae deposit their eggs in characteristic capsules, there are differences in reproductive strategies between species.

Three types of reproductive behavior have been described in science literature:. Freshwater species , for example, such as. They hatch as miniature adults, a crawling snail intracapsular metamorphosis. Estuarine species e stuaries form a transition zone between river environments and maritime environments , for example, such as. They hatch as planktotrophic veligers larvae, and they can show amphidromic behavior.

Marine species, for example, such as. They hatch as long-lived planktotrophic veligers larvae. Like Amano shrimp larvae , Nerite veligers are also attracted to the light. Therefore, lure them to a spot with a flashlight or adjustable lamp to the corner of the aquarium. Once they are in the right place, it is easier to feed the majority of them all at once. You can use this trick to feed them more efficiently. Note : Unfortunately, nobody has conducted any research how often Nerite snail veligers need to eat. There are scarce pieces of information that times a day might be good enough.

Yet again, this is the attempt to replicate of what they can possibly get in the wild. Golden Pearls Microns link to see the price on Amazon. Spirulina Powder mixed with water link to see the price. Phytoplankton Tetraselmis link to see the price. Well, this is another mystery. Some snails will lay eggs for a while and then stop completely. Others seem to lay in cycles while still others never lay eggs at all. I have read in one of the guides that Nerite snails start breeding rapidly to get an optimal number of species in the population. However, if you increase the number of snails simultaneously living in a tank, they will stop laying the eggs.

Honestly, I have not seen anything like that anywhere. I have a hard time believing it. You do not need a big one, gallons tank is enough. Leave the lights on for 24 h you need algae for the larvae to support them. Prepare brackish water — ppt. Increased temperature F will help to speed up metabolism and growth of Nerite snail veligers. Filtration — little to no mechanical filtration. It can suck them up. Covering inputs with a net or anything similar will not prevent it.

They are simply too small. An air bubble line should be set very low bubbles every seconds. When the tank is ready, move the item with egg capsules to the rearing tank. Note: do not even try to move the egg-capsules by scrapping them. You will damage them.

This is another uncharted territory. Larvae should not produce a lot bioload. Therefore, if your water parameters are good enough then there is no reason to do it. If you have nitrates, keep using the trick with the light to move any larvae over to one side, siphon from the other side, it might help to reduce losses. Nerite snail is a peaceful snail. It will not bother tank inhabitants. However, do not keep them with:. If you have other snails for example, you can read my article about Malaysian Trumpet Snail , they will compete with them for food. So, keep it in mind. The same is with Amano shrimp chech out my guide about this cool shrimp , actually.

They are also voracious algae eaters. Many shrimp breeders treat Planaria , Vorticella , Scutariella Japonica , Hydra you can read my articles about all these parasites and other parasites and diseases with Fenbendazole Panacur, Canine Dewormer , No-planaria, Benibachi — Planaria Zero. These medicines are very dangerous for all snails.

All nerite snails are excellent algae eaters that care mainly for algae coverings. They will be great neighbors in any shrimp tank. Unfortunately for some and fortunately for other, Nerite snails are extremely difficult to breed. Frankly saying, there is no difference in hardiness. More or less, they are the same. Most likely, it indicates that Nerite snail has been kept in water that is too soft and acid. The shell is dissolving. If you have soft water, it will be a good idea but in moderate or hard water, it is not necessary.

Note : You can use a crushed coral, and silica. They do not have an effect on the water. Yes, they do! However, these are not eggs but capsules. Each capsule contains about 70 micro eggs. There is no scientific study of Nerite crossbreeding. However, according to practice, they do not crossbreed. In general, I am not talking about Nerite snails, some snail can crossbreed.

No, they will not. However, they can damage some of the egg-capsules but it should not worry you at all because it is almost impossible to breed Nerite snails anyway. Hi I have one zebra snail and it has reproduced and at last count I have 11 baby snails. Nerite snails do not reproduce in freshwater. This is absolutely not possible.

Description and Appearance of some Nerite Snails Zebra nerite snail. The Diet of Nerite Snails. Algae All nerite snails are detritivores and herbivores and are widely known as one of, if not the most, efficient algae eaters out of all aquarium snails. How many Nerite Snails do you need? Keeping Nerite Snails Although they have a different appearance, their care requirements are essentially the same. Why do we fail breeding Nerite Snails? There are hundreds!

P eople have a different experience with different species , which look very similar. I have already mentioned that even the biologists have difficulties with this. So, when we start discussing this matter, the results do not match. Things start heating up, people call each other names and nobody knows for sure anything. This is not very productive. We do not really know their diet and cannot fully replicate their environment. In the past, more than once aquarists have seen similar examples. Just think about it. How do Nerite snails end up in freshwater if they can breed only in brackish water?

In some cases, it will take dozens of years for the snail to cross this distance. The egg capsules intracapsular development of Nerite Snails After mating, the females deposit egg capsules on any available substratum such as driftwood, leaves, including shells of other snails.

Larval development planktotrophic development of Nerite Snails After hatching, we have a release of veliger in the water. At a salinity of 5 ppt the capsules released veligers, after 21 days. At a salinity of 15 ppt, development was slower than at 5, and after 25 days, despite having well-formed veligers, they did not hatch at all.

Do Nerite Snails Crossbreed? For people like myself, such an aquarium is doomed to failure because it is so dynamically simple that boredom sets in and other demands from life lead to less than the required vigilance and maintenance.

Instead of an artificially sterile, demanding, and boring habitat, you can build a dynamic and robust habitat that uses natural elements of streams, ponds, and lakes: an alternative aquarium.

I thought I knew a lot about planted aquariums, but this direction of trying to create a little ecological system is really the next level, and I read it just when I was getting ready to set up a 29 gallon tank, and I'm inspired to give it a try.

Even my existing 5 gallon 'nano' tank is beginning to reflect some of this thinking, and it gives the whole endeavor a new level of excitement of discovery well b This is a lovely book, and it really inspires me to try and achieve an ecological aquarium. Even my existing 5 gallon 'nano' tank is beginning to reflect some of this thinking, and it gives the whole endeavor a new level of excitement of discovery well beyond all the stuff I thought I knew. And so, almost 20 years after I dismantled multiple fish tanks in my house in Norwalk, CT, everything I used to know is coming back, but this book is taking me a level deeper.

Very clear and concise, too!!! Can't wait for the next book from this author.

Spelling, grammar and technical misstatements makes the author 's non-traditional contentions at best questionable. Nov 02, Kellen rated it really liked it.
