OK people, its because of you that I had to go and get a peacock bass.I love this fish. I am totally addicted now! I will be posting pics later. I hope I followed all the right info from you guys. Here we go: Tank 40 gallon,temp 84, salt, lots of rosy reds, water changes every 3 days, some tasty tetras, ehiem 2217, wet/dry also, lots of air. Don't worry I have a 90 and a 300 he will be moving into. He is a OC at about 4 inches long. I have not seen him eat but did notice that the tetras were almost gone and some reds. I am going to feed him live only. He looks really beefy. He is starting to swim around like crazy. He practices chasing the reds all the time.Way to cool! I love these guys.Anyway thanks everyone for the good info!
