I just added some new plants (red ludiwiga & microsword) to my planted tank. several small snails and two amano shrimp were in with the plants. The snails are still around but the amano's are gone. I have a peppered cory, a julii cory and 3 bolivian rams that might have been the culprit. The rams seemed to ignore the shrimp and were all pushed around by a blue ram that was half thier size prior to separation. Also the tank temperature was 88F and all tank parameters were as normal ammonia 0ppm, nitrite 0ppm, nitrate 10 ppm gh 150 kh 120 ph 7.2. The only other inhabitants are a school of neons and a school of glowlights. I just dont think they are the ones that did it. Any Ideas?
