Shrimp are sensitive to nitrate so watch closely. You are as bad as the rest of us about getting more or trying this.I decided to try some guppies and shrimp together. I am silent cycling my 3rd tank with several plants and moss balls. I picked up 5 small feeder guppies and 5 small feeder ghost shrimp. They all are tiny, the guppies are little larger than fry.
