hi there, I recently set up a 10 gallon tank with only 7-8 snowball shrimp I picked up at an auction. It is furnished with a marina HOB filter, 150 W spare hydor heater, black sand and a few crypts and java moss. My question is, If i introduced other cardina or neocardino shrimp colors, will they cross breed with the snowball ones? Are there any other shrimps that won't breed with the snowball shrimp they'll get along with? Thanks. PS. I do not plan on adding fish to this tank.
