Bear Posted December 22, 2020 Share Posted December 22, 2020 (edited) pH = 7.2 (continuously monitored, by Seachem hang-in-tank, confirmed by API test kit) Nitrates =between 20-40 ppm Hardness = ? Nitrite = 0 ppm Ammonia = 0 ppm (continuously monitored, by Seachem hang-in-tank, confirmed by API test kit) KH/Buffer =? (I put a bit of crushed coral in whenever the pH drops below 7.0) Water Temperature = 75°F I've had 6 otos in a 55 gallon tank with 5 corys, 30 olive nerites, 100+ red cherry shrimp (only 10 adults rest are shrimplets in various stages of shrimplet-ness), and an estimated 10 Amano shrimp (I've only ever seen 6 at once, but I bought 10) living happily along for about 6 weeks. Trying to reduce the overall algae in the tank I bumped up the lighting from 10/hrs to 12/hrs and a twice weekly full dose of Easy Green to two pumps per day every day so I could start tweaking the light and fertilizer until I found the right combination. In the past week the otos have seemingly vanished one by one but I thought nothing it since I never found a body and I read that they can expertly hide. The day before yesterday the plumpest looking oto of the bunch disappeared and today I found a mostly eaten corpse of an oto but no other corpses at the bottom of the tank underneath a lush crypt. I'm super bummed that I lost all of my hyper glass-sucker puppies. Did I do something wrong? Did I miss something? Unusually bad luck?
