Assassin Snail Growth

Hey guys! So I have a ton of baby assassin snails, and I'm wondering if anyone knows how long it'll be until they reach about half an inch or so. I had started with 3, but I lost one (literally), when I moved and had to move my tank. The two that I have, however, have made a ton of babies. I noticed my first babies back in November, but they don't seem to grow at a fast speed or anything.

Also, should I remove them from the main tank? I have them in my 55g community as of now. I must have at least 100 of them. I'm wanting to sell them eventually, but they're so small, I don't see how I could do that now.

 

Here's a photo. It wouldn't load on the original post.

 

They look like trumpet snails not assassin. If that is what they are it will take a while - perhaps never. Mine are nearly 8 months old and the largest I've seen i think is under 1/2 inch easily.

 

Are they brown/cream with a white point? Or yellow and black?

 

Oh they might be MTS, I hadn't thought about it, really. They'd have had to hitchhike in on some plants. I would think my assassins would eat them, though.

 

Assassin snails breed very slowly and lay one egg at a time - unless you have a bunch they wouldn't produce a bunch of off springs over night

Well I appreciate the input! Thanks so much! I can still sell these guys, especially since they're overrunning my tank. The most assassin eggs I ever saw at once was like 4 or so. I'm pretty sure my shrimp ate them, though.
