Can a single male peacock successfully live a healthy life alone?

[Hybridfish7]

Just trying to debunk some things that I couldn't find answers to elsewhere.
But yeah, can a singular male peacock, let's just say an OB, live on his own, in his own tank, and still be healthy?
What affects would this have on the fish?
Would it show dominant colors for it being the only fish in the tank, as with American cichlids kept solitarily, would the fish just take its empty tank as its own territory?
If it is possible for one to live alone, how big of a tank would just one need?
The only problem I see with it (so far) is the aggression, but that wouldn't be much of a problem if it's alone.

A lot of big Cichlids & Hybrids are kept solo as Wet Pets and do just fine. The tank size required depends on the projected growth of the fish. Regarding tank size for your example fish, the OB Peacock, I'd go with a 29 gal. OBs grow to 6 or 7 inches. Once acclimated to his private tank, introducing a tankmate will be difficult. Funny you mentioned the OB Peacock.
I recently evicted my psycho, out of control OB from my show tank, and moved him into my Wet Pet tank. After quickly constructing a hardscape with plenty of hiding spots, the Red Texas and the OB get along.Lol.

I have noticed that Malawi cichlids that are kept alone will become increasingly more shy and hide more than normal

if they do work out like Stephen said, and don't end up depressed or skittish like Jread, then wouldn't it technically increase their lifespans? Since keeping them in a community is more stressful as a result of the constant fighting over territory and dominance, which would naturally shorten their lifespans
one of the main things that shortens the lifespans of fish is stress, whether that be from fighting or breeding, and I think it'd be interesting to see how the life of the fish would play out if i just got a small one and raised it alone in a 29, but along the way giving it enough attention to the point that it isn't skittish
big cichlids in tanks big enough to fit them but small enough that they can still interact with you usually makes them more personable, but that mostly applies to new world cichlids and some hybrids.

A well balanced community tank is not one where there is continued stress from dominance or territorial issues. Most of that should be worked out early on. In a male/female tank the only additional stress should be from more than normal spawning periods, compared to nature.

On a side note, I once owned an old A. jacobfreibergi that would not tolerate any female peacocks in his tank, if one was added he killed it, no matter the species. He spent most of his days in his cave, and gave an ass whooping to any fish foolish enough wander in to his cave. That old male would have done just fine on his own, and probably enjoyed the solitude.

I can relate, the older I get the more I feel like your fish.
