i would defenaly say 180, 180 are magical, it s just the perfect size tank. GET A LOOKDOWN FISH. we had one where i work no joke coolest fishi have ever seen. i gae it a tiger shrimo, the thing ripped it out of my hand wich suck ferocity i thoguh he was gonna morph into the hulk!! frigging so so so so s os so so so cool.i wishi had a video! i mena i just cant tellyou. and wolf eels are sweet, there not actually an eel so they can actually see and interact wiht you, true eels are escape artist and unless youget a large morrey are as fun as whatching poop float cuase thats pretty much all the do, and they are more of a scavenger then a hunter cause they can only smell their way arond. groupers are fun but skiddish a times, miniatus especially, i had one, sweet looking fish, but super super skiddish.
octopus are sweet, they are extreamly intelligent and have no bone in thier body. the only hard structure in thier body is thier beak, and they can fit thier entire body thoguh what ever that beak can fit through, so depending on the breed, your looking at a animal that is smart enough to find, and curious to fit himslef though any hole or crack the size of a nickle. they can also force open anythignnot really weighed down. and they will wxplore and they will find! so youhave to octopus proof your tank like there is no tommorow. also they live relitively short lifes. some becuase of the breed other times because they get depressed, these animals need stimulattion. notl iek fish who are happy swimming around the same rock fending off all intruders. no you have to give them games and toys. for instance we take plastick easter eggs fill some wiht treats, some with pebels, some wiht air, some wiht a random object and our girl will go and open them all exploring the contents and even shakes them, she loves the ones with air and watchign them float. making her food interactive is a good way to entertain them.
a few other things that create problems, they will eat everythign if you get a octopus tank you get, and octopus.
also if females lay eggs they become extreamly aggressive and will attack anythign by the tank
and they tend to be nocternal so they hide alot. so yeha.... here is a pic of a lookdown fish
