Panda loach
Yaoshania pachychilus
Hillstream loach from fast, highly oxygenated mountain streams; thrives in a mature, algae/biofilm-rich river-style aquarium with strong flow and smooth rocks. Peaceful but social, and best kept in groups where they become more active and confident.
Skunk loach
Yasuhikotakia morleti
This is the little loach with the bold black "skunk stripe" down its back, and it acts just as sassy as it looks. Give it a group and a pile of caves and it turns into a busy, clicking, bottom-patrolling gremlin that will happily hunt snails. It stays fairly small, but it can get nippy if you try to keep just one or you pair it with slow, long-finned fish.
Gjellerup's snake eel
Yirrkala gjellerupi
This is a tiny little freshwater snake eel (worm eel family) that lives a pretty un-eel-like life, turning up in streams well away from the sea. It is one of those obscure oddballs you will mostly see in scientific papers rather than aquarium shops, and that rarity is honestly part of what makes it so interesting.
Yellowfin toxic goby
Yongeichthys criniger
An Indo-Pacific goby found on coastal mud/silty sand flats and in estuary/mangrove-associated habitats. It is documented as poisonous to eat and is known to carry tetrodotoxin; toxicity can be particularly high in the skin and varies by locality. Handle with care (avoid contact with mucus, especially with cuts) and avoid mixing with aggressive/boisterous species.
