I don't think pressure is an issue I have kept American lobsters alive for days at work in a five gallon bucket during the colder months. I work on a commercial fishing boat and lobsters are a common by-catch. just thought it might be cool to set up like a north atlantic native tank. lobster, scallops, mussels, various crabs and some black sea bass. maybe even a codfish but I don't know how the cod would fare during the transition. seabass I have kept alive for private customers before so I don't see it being an issue and they are beautiful once they mature. they develop a large nuchal hump and some amazing electric blue colors. thanks for the input guys. I am going to keep it in consideration. when the time comes I am going to be torn between expanding my amazon stock or starting a new theme all together. if I buy a bigger house with a basement maybe my wife will let me have both. hahaha.
she was clearly traumatized. Very cool looking lobster, looks like our Spiny lobsters on the west coast, but colorful.
