DaveK: I have seen numerous aquariums set up by the sea shore using NSW. Animals were collected from a variety of locations and placed in captivity.
None of the tanks I saw were managed by aquarists that understood the bio-tope approach to aquarium keeping.
E.g. Animals from one part of the reef were kept with animals from other parts of the reef. Their captivity was unnatural as natural predators were kept with natural victims.
Filtration and lighting was not an issue as the animals started competing for living space almost immediately. There was no understanding of animal husbandry or compatibility of captive marine organisms.
This was as recent as 2006.
