Are these assassin snail eggs...?
 
I've got a 28gal tank with the following: 1 male dwarf gourami, rummynose tetras, harlequin rasboras, cories, otos, amano shrimp, nerite snails, MTS and one assassin snail. I'm pretty sure these are assassin snail eggs, but I figured I would mention everyone else in case there's another option.

Everything I'm reading says you must have a male and female assassin snail to reproduce, and I only have one, but I've got a bunch of little square eggs on a piece of driftwood and the roots of the anubias I have tied to it. At first I thought they were nerite eggs cause these showed up at the same time my nerites went on a random egg laying spree.. but upon closer inspection these are not the hard, round eggs like my nerite's lay. Are these indeed nerite snail eggs, and if so.. how? I've had the snail for like 2-3 months in my tank without another snail of the same species. Is this something that's likely to keep happening.. and are the eggs even fertile?

I could be wrong on this, as I don't actually OWN assassin snails, and have never done research on them, specifically. I do *believe* that I've read somewhere that this type of snail may be able to 'hold' eggs for a short time after fertilization before depositing them. Squarish and squishy sure sounds like Assassin eggs to me, and since you're familiar with Nerite eggs, I'm sure you're correct!

I suppose it's a possibility that they do as the Nerites do, but I don't think so, because (as far as I know) Assassins actually mate, so I don't think they're the type to drop eggs willy-nilly like the Nerites so love to do.

Sooooo. . . whatcha gonna do with 'em? Are you going to see if they make it into bitty baby Assassins? Or try to stop the hatchery now - I'm assuming that you only have one assassin for a reason, lol!

Maybe someone who knows more about this species can lend a more helping hand! Let me know how it goes!

I had thought maybe she (apparently it's a she..lol) had been holding the eggs, that just seems like a very long time to hold them. I'm looking back and I had asked the LFS if they had them for sale April 25th and I know I bought it within a couple days or that. I guess that is only like 2.5 months but that still seems like a while to me. I hope she doesn't end up laying more.

I have no idea if they would've already hatched in my tank or not. I noticed them, but I didn't notice the shape until they'd been in the tank for like a week. I removed the plants and driftwood they were on from the tank and plopped it in a bucket outside and then when I was removing the anubias from the driftwood I noticed that they were not nerite eggs. There was even a baby snail that could've been an assassin snail on the plant.. but it could have been an MTS too. I killed it thinking it was an MTS. I guess I will just have to wait to see if any survived. Some of the eggs looked like something was in it.. some honestly looked like something had hatched out. I may have a new pesty snail in my tank! Although, they'll still do the same job as MTS pretty much do... and they'd eventually kill off my MTS. I will just need to worry about feeding them when the MTS run dry. I also worry about my nerites, tho I know they are already harder for assassins to eat and they're also larger than the assassins.

I guess we'll just see!! I will certainly update if I ever see babies.. I wonder how long til I see them come out. I hardly see the momma.

Thanks so much for your input!

Aww! I love my MTS!!! To each their own, I suppose! Please do let me know if you should happen to find any baby snails. . . at least you know they'll take care of the others you don't want in your tank! The smaller snails sure do have a way of becoming a part of a tank, don't they? lol!

I don't hate my MTS.. they're just always everywhere. I thought they'd mostly come out at night but they're very active. They eat my fish poop and clean up any plant debris though so I do like em. I just wish they would disappear sometimes.

There seems to be a whole lot of them, and I don't think I over feed cause I don't see really any flake going to the bottom.. and my corys and rummys eat up almost all the pellets, except some tiny pieces they don't notice.

Well. . . just because the fish EAT all of the food doesn't *necessarily* mean that you don't overfeed. There's always the end result of the food that has been eaten, which has just as dramatic an effect on snail population! I have MTS, I do see them during the day, but their numbers have always been low in my tank. *shrug* Who knows? Maybe they just like you :D

I think they're eating a lot of plant material.. I got some red root floaters in and I don't know if the MTS just love the way they taste, or if the plants are actually dying and then they're eating them... but they've been climbing to the top.of my tank and getting my RRF and eating them. There are a lot missing, but the plants remaining look to be in better shape... they've also been eating on another plant I wasn't sure would work out.. I think the leaves on it are melting so they're eating the leaves... or they are eating my plants in which case I completely dislike them, lol.

I don't sit there feeding my fish for 5..10.. minutes. Probably only like a minute.. idk. And I usually skip like every fourth day. I don't know.. my water parameters are OK and my fish aren't super fat so I don't really know if I am actually overfeeding or not.

Aaaaahhhh... makes sense now :) I've never known of MTS to eat living plant matter, so they're probably keeping up with cleanup as the plants adjust to your tank. . . they'll die back once they run out of food!

jennesque 07-20-2012 02:32 PM

Here's hoping so. I hadn't really seen them eating live plants before but because there's so many I can never really tell how poorly the plant was doing before they started munching. The one plant is only like an inch tall with tiny leaves, and the RRF are pretty small as well.

And then cause they're eating the plant matter, that's probably why they're out all the time cause I used to only really see a lot of them when I was feeding cause the shrimp pellets seem to attract them.
