Need Vittina Usnea " Olive Nerite" Info Please...

[kj23502]

Are olive nerites good for SAP food? I've read on a few different sites that it can be tricky to breed them and they only breed in brackish water. Even if they breed in brackish water they usually don't survive? Would a sg of 1.003 to 1.005 be ok for breeding and keeping them? I'm trying to find a brackish snail that reproduces prolifically in a brackish tank for automatic puffer food. I'm hoping I won't have to set up a breeding tank for snails just for puffer food. Although, I will if I have to!

I plan to heavily plant the back of the tank and lightly plant the front. (so the puffers have open water for swimming). I'm putting in some driftwood and slate so I'm hoping that any snail I put in to breed will have ample opportunity to grow for a bit and breed before getting eaten.

Will bumble bee gobies eat snail larvae? (not sure if that was a stupid ? or not ) I plan to have quite a few of them in my tank.

Or any other ideas on snails that will breed and grow in brackish water? What about Malaysian trumpet snails? As they will also keep the sand turned and hopefully help with algae.

Breeding Olive nerites is no easy task, otherwise everybody would be doing it.

You're better off using a separate tank to raise snails for puffer food.

Any idea what is required to do it successfully? I'm totally curious. Do they really get washed from freshwater (after hatching) to the ocean and then make their way back as they "grow up"?

Quite honestly, I'm not sure. I believe the eggs hatch into larvae, and go through several forms before actually turning into snails. I'm not sure what triggers the eggs to hatch, or if the young needs salt to develop.

It could well be similar to the information given by me on this thread.

Wow...so that sounds impossible!!!

What about malaysian trumpet snails adapting to lower brackish water? I've read a few sites that say they can...

 

[dizzied]

MTS does very well in brackish (and probably all the way down to saltwater), but it isn't ideal puffer food I would think. Another common snail that could adjust to brackish are Columbian ramshorns, but those are rip apart your plants.

Perhaps there's a species of pond snail that could adjust to low brackish?

I believe sap's are more inclined to bite off the foot than try and break the shell on mts. I think neale said that somewhere?? but don't quote me. So they shouldn't break their beaks.

yeah... one of my nerites, a part of its foot is missing because of my puffer... The shell of the nerite is way too thick and hard for my puffer to bite through.
