I just purchased a tiger datnoid, under 2 inches, and put him in a 50 gallon breeder. At the same time, I added an electric blue jack dempsey, a julidochromis regani, a melanochromis auratus, a pseudotropheus demasoni??, and 4 synodontis petricolas. The datnoid is probably the largest fish of them all. The tank has been up and running for around 8 months, just restocking, and the levels are fine. My problem is the datnoid is the only fish that isn't eating, and it's been 4 days since they were all added. Since he was getting picked on, I moved him to a 10 gallon containing 3 goldfish in fear he wouldn't make it in the 50 gallon. Only minor injuries. He is very sluggish, just sitting at the bottom, moving occasionally. Any sugestions???
