About 6 months ago i bought some shrimp off ebay. They are in a planted tank with a bunch of guppies. Nitrate, Nitrite and Ammonia are all as low as possible and i've never seen a trace of any of them except for a little nitrate. The only time i clean it out is to get the hair algae out of it but it gets pretty bad before i actually get off my lazy *** and do it. What would make a cherry shrimp not bread? I started out with 50ish shrimp. I might have a hand full left. The hardness is 75 (soft), the ph is between 7.2 and 7.8 and the total alkalinity is about 120. any input would be appreciated.
