Hi! You shouldn't have a problem. I have a snail that has thrived for several years....it was a tiny thing that accidentally got into the bag when I bought a bigger snail...that one died fairly quickly, but the small one thrived and is now nearly 3 inches long and just about as tall...he's gorgeous! They're easy....they take care of themselves and find algae to suck on when you think your tank is clean. And if the conditions are right, they asexually reproduce, meaning they don't need a mate. I've been told a sac floats on the top of the tank and it's up to me whether I let it hatch or throw it away....knowing me, I'd leave it alone because I could never knowingly kill anything, but it's never happened. But they're neat to have and keep your tank pretty clean and are very low-maintenance. I'd stick to two at the most, though....the more you have, the less food each has, and then they'll die off. One is plenty for a ten gallon.

Good luck!
