No Mike I'm sure your tanks are all absolutely breath taking and healthy. It's was very early in the morning and my mind wasn't quite processing properly - my bad sorry ppl.
What I meant was is that multiple peacocks can present problems, I've witnessed it 1st hand with multiple Jake's in the same tank at lengths of 6 and 8'. I've seen my Dom. Euerka Red stress my Lemon, Bi-color, Red Shoulder, and Butterfly to the point of bad coloration, disease, starvation, and death. There is plenty of documented warnings about housing multiple Aulonocara in the same thank. Those warnings mirror what I've experienced. There are few absolutes in fish keeping, most compatibility issues depend on the fishes individual personalities. However, housing multiple peacocks can lead to compatibily issues - something to be aware of and hopefully avoided.
