Tank size relates to aggression: tank size relates to aggression; tank size relates t

Please believe that if you put fish into a too-small tank, you get aggression. There are some species that will eat each other. That's lunch, not aggression. But if fish are fighting, the remaining issues are mating, or the tank is too small for the fish that are in there. There are a handful of fish that are just nippy on anything in reach---the 6-line wrasse and the dottyback;...but for most, give them enough room and they have better things to do than chew up the neighbors.

I have long believed that stocking a tank is as much an art as it is doing the research on the fishes.

Very true

So is rockwork---with some species. I've found, running damsels, that they're wanna-be architects: everybody wants his own skyscraper, or if small, to run in the 'court' of a large damsel who's got one. I arrange to have various knobs of rock that seem to be 'home base' for certain ones. Sometimes rearranging the rocks helps.

And certainly many fish will take exception to another of their kind at too close a distance, where other fish would be ignored swimming in and out.

I think its also good to do research on fish that will occupy different areas of space, goby for ground/low, blennies/hawks on the rock, open swimming etc. May help when stocking a tank to fill all the fields.

Very true: species that occupy different zones don't tend to come into conflict.
