We bought a pair of Freiberg's Peacocks to go in our 29 gallon aquarium on Monday evening. In the tank also is one Altolamprologus compressiceps that eats wonderfully, one danio that eats great also, and a golden algae eater. We have tested the water PH, which was approximately 7.8 to 7.9, the amonia levels were perfect, and the nitrate levels were perfect also. The temperature is at approximately 78 degrees. Yet, the Freiberg's Peacocks will hardly eat anything. We have tried flakes, two different kinds of floating cichlid pellets, Tubifex worms, live goldfish, and shrimp pellets. The large male Freiberg's Peacock has eaten maybe one shrimp pellet all week. He would eat one of the tubifex worms and then spit it out, same with the shrimp pellets after he ate one a few days ago. We haven't seen the female eat anything. Is there anything we can do or does anyone have any idea of what may be wrong with them and why they are not eating?
