What Snail Should I Choose?

HI everyone! I have a ten gallon tank that's filled with algae cause my 3 zebra nerites died from the recent power outage we had. Currently I have 3 zebra danios, and a bunch of cherry shrimp in the tank. I wanted to get more zebra nerites, but the pet store I work at doesn't carry them. My manager told me she could get olive nerites, mystery snails, asassin snails, and ramshorn snails. Which do you think meet my tank requirements and would be best for cleaning up algae? Also about how many do you suggest I buy? Thank you!

 

The olive nerites.

 

I'd also say the Olive Nerites.

 

Olive nerites as well. None of your other choices are efficient algae eaters from my experience.

 

Olive nerites it is then! About how many? Is three a good number?

 

I would do one in a 10 gallon. Three is to many and you'll will need to supplement a lot after they clean your tank.
