@FunkyGibbon this tank houses Houndfish (Tylosurus crocodilus), Striped Bonito (Sarda orientalis), Mackerel Tuna (Euthynnus affinis), a Bowmouth Guitarfish (Rhina ancylostoma) and a juvenile Tiger Shark (Galeocerdo cuvier). The tank is the same donut tank that houses the Bluefin Tuna, but dividers have been used to separate the fish. I suspect that the Bluefin Tuna were building up too much speed being able to just swim straight and damaging themselves, so the dividers make them have to turn, keeping the speed down.
As of March this year, this tank now houses:
Javanese Cownose Ray Rhinoptera javanicus
Scalloped Hammerhead Sphyrna lewinii
Blacktip Reef Shark Carcharhinus melanopterus
Bowmouth Guitarfish Rhina ancylostoma
Kawakawa Euthynnus affinis
Striped Bonito Sarda orientalis
Pacific Bluefin Tuna Thunnus orientalis
Japanese Scad Decapterus maruadsi
Japanese Pilchard Sardinops sagax melanostictus
