Snailfish

Which species? I'll add the info on Zootierliste.

@Sicarius species wasn’t specified.

Wow!!!

@Sicarius @DaLilFishie I tried to post a video but it wouldn’t work. I’ve put it on my instagram @travel.plants.stuff if you wanna check it out over there

@akasha just went and had a look. Gorgeous! I love the huge pectoral fins

@DaLilFishie I know, right! One of the highlights of the collection.

I found a blog post from Osaka Aquarium mentioning this fish, which refers to it as カサウオ, which could be a hint for a species identification - this name refers to both the species Liparis tanakae, as well as snailfishes more broadly. Regardless, I would suspect this fish is a member of genus Liparis. Unfortunately, as of my visit in April it is no longer on display.
