    If the bags were freshwater, they’d float on saltwater. Not to that level – just barely floating…

    But the fish are saltwater fish, so the bags need to be saltwater too, for them to survive. So the water levels should be identical or very close to the harbour.

    Yeah, it’s bothered me too ;)

      What if the air inside was hotter than that outside? I think in the bags there would be a greenhouse effect…
