S.E.A. Aquarium - Open Ocean

Looks very impressive! I look forward to seeing it.

re: sailfish. Aquamarine Fukushima was hard hit by the 2011 earthquake; if any of their sailfish survived that long, they certainly died in the aftermath of the earthquake. However, they're now considering sailfish at Port of Nagoya Public Aquarium in Japan. To scare their sardines: What Do You Do When Aquarium Sardines Start Acting Fishy?

The sailfish is a remarkable species, but clearly should only be attempted by aquaria with very large tanks. For the larger marlins (Istiompax+Makaira) and swordfish I suspect even the largest aquarium (Atlanta) currently in existence would be insufficient.

NB: Genetic and morphometric evidence has now confirmed what many had suggested earlier: Indo-Pacific and Atlantic sailfish are identical = 1 sailfish species with a circumtropical range. (based on limited cladistic evidence, there might actually be a second Atlantic species, but its range is overlapped by the range of the circumtropical species.)

Zooish, did sailfish ever appear at this aquarium? If not, do you still think that they might someday? How are the manta rays doing?

@DavidBrown No, sailfish never did appear. I personally don't think it will happen. The 3 mantas (all males) are doing well, but with the ban on capture of wild mantas in effect, it seems unlikely too that the aquarium will be able to acquire new specimens.
