Based on much observation (
) my tank has very well defined fiefdoms.
The upper left corner is "Maroon Corner." Occupied by my pair of mated Maroon clowns and monster BTA. They generally are pretty leinent about letting other fish (except the damsels) wander about in their space unless they have eggs laid down (which is most of the time) - then woe to anyone who even appears to be getting close to their corner.
The lower left corner is "Wrasse country" --- they generally are the only ones to hang out there. Don't really defend it if somebody else wanders in. And generally like to play about in the heavy current that is in that part of the tank.
The center of the tank is pretty much "open" space where all can gather and socialize generrally pretty peacefully. Except near the bottom where a, at times, is a very grumpy shrimp goby. Any hermit entering his space can be expected to be dragged into his den. (no harm to them - just a temporary captive) - He will often "charge" other fish approaching his hole too closely.
The bi-color blenny stays perched in a crevice at the highest part of the center of the tank, where he can keep an eye on all going on below him. He will make quick dashes to other areas of the tank, but quickly returns in short order to his favorite spot.
The upper right section of the tank is the "Damsels territory" --- any fish visiting that area is likely to be run off by a pair of blue yellow tails and a pair of Humbug Dycilus damsels which control that space. They usually just sqabble among themselves and leave everyone else be, except for that corner of the tank.
For some reason the Coral Beauty, which wanders just about anywhere, periodically seems to enjoy going into the damsels area and mixing it up with them. Alot of chasing about with no real harm coming to anyone.
The only fish that can go anywhere without being bothered by anything or anyone is the little dragonett. Which is so utterly peaceful and just intent on inspecting every little hole and crevice for something to eat, that all else just ignor him.
Ok, that was fun - what "boundaries" do you have in your tank?
