Can Different Nerite Species Interbreed?

Sue's Nerite pictures in Gallery Showcase show quite a range of different nerites. Also, quite a few eggs. I currently have 4 Zebra Nerites in my 125l, and a steadily increasing number of eggs. Some of the eggs are in places that I didn't think a large Nerite could reach, e.g. the top section of a vallis leaf.

Does anyone know if different species of Nerite can interbreed? Because, if not, then the solution to the "egg"  problem might just be to only have one of a few different species. Not only that, but they would add more colours & variety to the tank.

Since nerites need a male and female to produce eggs, I assume they can only breed with the another snail of the same species. The different patterned ones should be different species.

I've only ever had nerite eggs when there have been at least 2 of the same colour/pattern. With the 6 in the 180 litre at the moment, I have no new eggs, and they can't all be males.
I did have 2 of the grey ones (type #1 in the snail thread) when I first got them and one of them laid eggs everywhere, including on the tank walls. None of the previous snail breeding resulted in eggs there! Since I separated the grey ones there have been no more eggs.

I've had a red onion snail (#5) in with what looks like a different patterned red onion (#2) but they are different enough to be separate species and there have been no eggs.

Just to be clear :
hermaphroditic = each individual has the organs of both sexes within it. They still have to mate to produce viable eggs.

not to be confused with :
parthenogenetic =  able to reproduce without mating (e.g. Indian stick insects)

Many snails are hermaphroditic, don't know if any are parthenogenetic. The eggs laid by unmated snail may be sterile.

The reliable information is that nerites are neither.

Depending where you read, malaysian trumpet snails are reputed to be parthenogenetic.

MTS are known to be viviparous, giving birth to live young as opposed to laying eggs. I wonder if some people are confusing this with parthenogenesis.

I have three nerites: a black olive, an onion and a zebra. I have eggs everywhere. Therefore I don't think splitting the varieties will do anything to stop them laying eggs. You just need to be lucky and only have boy nerites!

My morpani wood looks like its been dipped in sesame seeds    Not a good look

I've had 2 of the snails for over 4 years (zebra and red onion), one for just over 2 years (bee nerite, actually a Clithorn species which shouldn't breed as that's the only Clithorn), and 3 for just over 1 year (red and black one which isn't quite a red onion, black with very thin brown zigzag stripes) and grey (which I think might be a Clypeolum and shouldn't breed with any of the others). They should be settled by now!
I do have another grey one which used to be in the 180 litre but the two of them bred so I separated them and no more eggs since then.
So of the 6 snails in the 180, I'm pretty sure that 2 of them are singles of two different species. That leaves the other four as possibly different patterns of the same species.

My daughter's boyfriend had one Nerite snail in his tank and has eggs covering his Mopani wood.

I have to say that nerites are fantastic algae eaters. I clean my glass once every couple of months and they keep on top of it the rest of the time. I can see their little teeth marks in the little algae that is remaining. Amazing!

This is why I'm prepared to put up with the eggs
