DEEP fish

I don't believe you need a pressurized system to house deep water fish. I think if you mimic their environment (aside from the crushing pressure), you should be able to house them. The trick is getting them to the surface without killing them. They can still suffer from the bends if they come up too quickly. There isn't just oxygen dissolved in the water, there are several gases dissolved, including nitrogen. So, if you could get a fish and if you were careful about bringing them up from the depths, you should be able to keep it! That's just my opinion, though.
Most "deep water" fish such as Frontozas could be kept in regular tanks. It is only tricky to bring them to surface alive when catching them in the wild. Even that could be over-stated since all the black sea bass I hooked with bottom jigs from 30+ feet deep water off the fishing pier were all alive and I kept them in buckets with no problem while I kept fishing. Are you talking about marine fish that live 1000+ feet deep?
I've often wondered the same thing. It would be my dream to have an aquarium full of fish like the one in my avatar, but I've never seen it done before. I'm not sure if its possible, and its definitely not practical.
Plus, you have to think that they live in an environment where there is almost no light at all which would probably have to be replicated to keep them healthy, so how would you even view them?

I don't see why you would have to mimic pressure in an aquarium. It would be quite a challenge to do in the first place, let alone working on the system (imagine if you had a fish die and you had to open the tank. What a nightmare!). But, I have to agree with Surfcast2010 about "deep water" stuff... The greatest relative pressure change you'd see while diving occurs between the surface and 32' down. The pressure goes from 1 atmosphere to 2 atm here. This is associated with a FAR greater change in volume of any air than anywhere else (this is why you can be seriously injured while doing "shallow" dives... you can get an over-expansion injury without even seeing water deeper than 30'!) Furthermore, you can pull a fish up from relatively deep depths without harming it, but it MUST dive back down for any decompression sickness symptoms to leave.
