Very Interesting!

It's nice to see that they are shown in aquaria now. But of course the fact that these antarctic icefishes lack erythrocytes (and so haemoglobin) is already well known. And these are no deep-sea fish, this ocellated icefish would have a vertical distribution between 0 and 1000 m. But I guess obtaining these in a healthy condition and keeping them alive with their special requirements for cold, highly oxygenated water may still be a difficult task.
