In the last day or two I have had about 4-5 shrimp die on me. I am down to about 2-3 left in my tank. I figure these guys are about to kick the bucket as well, and I am not prepared for it. I am more concerned with what happened in the tank for this suddenly to sudden die off. My ph has always been around 7.2 and I am using aquaeonn water conditioner. I use the 5 ml of for ever 2-3 gallons changed. No nirates or nirite spikes, no ammonia spikes showing on my master test kit. I had a major seed shrimp explosion, and now their population crashed a long with my shrimps what is the deal? I did drop food in there to make sure that was not the cause.
