Breeding Aselone spixi - zebra apple snails

Hi there.

 

I acquired a group of 11 or 12 Aselone spixi earlier this year. They are somewhat related to the apple snails, which are now illegal to trade or even give away within the EU. The Aselone spixi are perfectly legal though.

 

I've realized that when well fed, they lay a cluster of some 20-30 eggs below water - as is usual for this species. I often find 4-5 new clusters of eggs every week. Unfortunately they're quite fond of eating smaller snails, and that includes their own offspring and younger siblings. Because of this nasty habit, I'm only up to 22 snails by now. I have tried giving a cluster or two of eggs their very own aquarium, but that usually leads to just one or two snails making it to a size similar to that of a pea.

Does anyone in here have any experience with these snails and maybe some tips on how to breed them in larger numbers (and do not suggest one aquarium per snail egg - I don't have that many aquariums).

 

Thanks in advance,

Plesner

I raised 40-50 in a 5g tank to 1cm: good enough?

What is needed is to feed them well (I used Sera Micron then algae wafers) and to change water frequently (they need loads of Ca to grow, but I did not want to put too much of it at once -- the tank was also used to raise 100 cories -- so frequent changes was the alternative). Of course water should not be too soft and must have pH>7.la

Pretty but very nasty snail, btw,... I spread them around to discover their ability to destroy cory eggs deposited on the glass faster than I can notice and collect them :( Ramshorns are much safer for consuming excess food.

Thank you Michael.

 

I do feed them a lot. I don't change water on the young snails that often. A clutch or two of them were put in 54 l/14g tanks. Our tap water is slightly basic and very hard (occasionally referred to as liquid calcium).

 

I don't keep any cories and it does seem to be a decent alternative to apple snails, which are no longer legally available within the EU. I did know about their tendency to eat eggs (and snails - apparently even assassin snails). I will make it a rule only to keep them with livebearers and other fish which are unlikely to leave eggs in the aquarium.

Powdered food seems to help with young snails... and they need A LOT of calcium so I'd guess water changes will be beneficial even for your hard water... otherwise they compete with each other for Ca and nobody gets enough, thus most die.

I believe they eat ramshorns too, at least there were very few ramshorns surviving in spixi tanks.

I know this is an old thread and all, but I was wondering why the EU banned apple snail trading or giving away? Invasive species risks or other reasons?

Threats to agriculture in southern Europe, particularly the Iberian region where rice growing is important (even though this is itself putting species at risk of extinction).

By moving the Aselone spixi into several of my tanks with tiny livebearers (Heterandria formosa, Neoheterandria elegans and Phallichthys quadripunctatus) all of which are regularly given powdered foods, the total number of snails seems to be growing at a steady rate and a lot faster than before. That was really a helpful piece of advice.
