What to add to my little tank (: 10 Gallon Tank

Well currently I ONLY have balloon mollies in this tank and I absolutely love it. But I'm thinking I'm going to want to add something to help keep the bottom clean. Right now I have 7 total in the tank (with two fat prego females) and I'm wanting to add something that isn't going to add a huge bioload to my tank and I'd prefer something that won't eat fry as this is a breeding tank.

I was thinking ghost shrimp or something along those lines?

 

Shrimp work well with most fish and will be safe with the not so fast balloon mollies.

Shrimp do not add much of a bio load and clean up the tank a little more if anything by eating any left over fish food

 

Will the shrimp eat the fry, though?

 

I would think most shrimp will go for the fry. If this is for your 10gal, I would just leave it as is. 7 Mollies is alot for a tank that size.
