Wow wiggles. Excellent read. Did u write that up yourself? Now correct me if I'm wrong guys but from what I gathered after skimming through that species profile that wiggles directed me to, it looks to me like if I up the tank size a lil bit I could house these sharks. Now I also understand they all can't go together due to temperature difference. But here's my list I came up with. Arabian and grey bamboo, marble, coral, Bali, chain, cloudy, and gulf cats, dark shyshark, puffadder, speckled and triton bay epaulette??
No, I didn't write those myself. That's easily the best forum for finding out excellent information on sharks & rays, though.
I would avoid anything that's going to require a chiller since that's going to be pretty costly to purchase & run while also limiting your options for tankmates. As such, I would avoid the chain catshark, cloudy catshark, Gulf catshark, dark shyshark, and puffadder shyshark due their need for cool/cold water temperatures. As for your other options, I'm partial to the coral catshark due to their coloration; they're also supposed to be very hardy & easy to obtain. Keep in mind that adult males of some species may be territorial with other males regardless of species.
