Hi, been breeding Red Cherry Shrimps for six months now and getting lots of tiny shrimplets. I added Crystal Black shrimps and they grow fine. I have about 4 in the tank now for five weeks. During the 6 months I lost 2 Red Crystal Shrimps and today feeling confident placed a new one which died within minutes. I acclimated it by placing the bag in the tank for 5 minutes and then added a bit of tank water each at a time for 3 times before releasing shrimp into the water. I had two beautiful yellow shrimp last month but they lasted a week before they too perished. So far, 2 yellow shrimp, 1 orange shrimp, 3 Red Crystal Shrimps all died. What I have in the tank are Red Cherry Shrimps, at least 4 Bee Shrimp, 2 Tiger Shrimps. My temperature reads 26, Ammonia and Nitrates are 0. PH is about 7. I have used Beta Glugen powder. I feed HikarI Shrimp food twice a day. What should I do? Feeling like I lost the plot. All the shrimps are from the same fish shop. The RCS do fine and breed a lot. I change water twice a week. Tank is 14L and planted with Java Moss and with a sponge filter. I use a gravel siphon to clean the substrate.
Updated test readings: ammonia and Nitrite both at 0 ppm. PH 7.6 ppm and Nitrate 5 ppm. API liquid testers.
