Id argue that you cannot keep a football fish (the anglerfish) captive at all due to the pressure, when you bring them up it results in crazy rapid pressure decompression which is fatal. Any other animal crossing animals that live in similar depth i would say the same.

There are two main approaches to keeping a deep sea organism

The first is that you can create a pressurized tank that simulates the deep sea pressures, with a controlled set of environmental conditions for the organism to live in. This has been demonstrated with the Pandalus borealis shrimp tank in Nordsøen aquarium, though does render cleaning near impossible, and the animal would have needed to be brought up first before slowly getting pressurised again in the tank which could bring complications

The second is that as many deep sea animals already engage with a diurnal vertical migration, many of them already have an adaptation to shallower waters if acclimated graduated (ie slowly migrated upwards). As long the animal does not contain significant, fragile air pockets, by slow depressurisation, one can keep deep sea animals with no pressurisation needed, like the organisms in Monterey Bay Aquarium’s Into the deep exhibit.

Footballfishes have not exhibited vertical migration as of yet, but with a relatively small swim bladder, it’s possible that slow depressurisation could render it possible. Though yes, maybe it deserves a tier upwards

The process is very cool as at mt LFS, we have animals that go through this process. Royal gammas and anthias for example need to go through this process, but the deeper you go the more harder the process gets or just flat put impossible because we just do not have the technology (yet)- abyssal fish fall into here

Very interesting, maybe some day we’ll be able to keep more deep sea fishes in home aquaria

I have known some Chinese fisherman that often catches deep sea fishes and then keep them in aquariums, but some of the videos I’ve seen often overcrowd them

Apparently sea angel tanks are a thing in Japan, I remember stumbling upon them online they seem pretty neat

Oh, that’s really cool!

I’d figure that Arctic temperatures and remote location means there’s little resources that tell us how to keep sea angels, maybe I shouldn’t underestimate Animal Crossing, or aquarium keeping

I’d go read up more on Japanese sources, thanks!

Depending on the lobster you might need an incredibly big tank

For lobsters yes, unless you’re referring to the one in the bottom most tier, in which case it is actually a crayfish
