Bumblebee goby
Brachygobius doriae
Brachygobius doriae is one of the classic "bumblebee gobies" - tiny, bottom-hugging little characters that perch on rocks and sand and stare at you like they own the place. They're at their best in a calm setup with lots of caves and leaf litter, and they really shine once you get them eating frozen/live foods reliably (they're slow, picky eaters). Also: they're one of the species that gets mislabeled a lot in shops, so it's super common to see them sold under the wrong bumblebee-goby name.
Bumblebee goby (Bumblebee fish)
Brachygobius xanthozonus
This is that tiny little goby with the bold black-and-yellow bands that likes to perch on the bottom and stare back at you like it owns the place. It's happiest in lightly brackish water with lots of little caves and sight-breaks, and it's one of those fish that often refuses flakes-frozen/live meaty foods usually flip the "yes, I will eat" switch.
Bunguran rasbora
Rasbora bunguranensis
Rasbora bunguranensis is a small, schooling Rasbora from Indonesia's Natuna Besar (Bunguran) Island. It stays pretty modest in size (about 8 cm standard length), so it fits that classic Rasbora vibe: active midwater cruising and happiest when you keep a proper group so they feel confident.
Busuma tilapia
Tilapia busumana
Tilapia busumana is a West African cichlid from Ghana/Côte d’Ivoire drainages (including Lake Bosumtwi). It is a pair-bonding, open-substrate spawner with biparental brood guarding.
Butterfly stingaree
Urolophus papilio
This is a deepwater little stingray from the Chesterfield Islands area (Coral Sea), with a super wide, diamond-shaped disc that earned it the butterfly name. It is a bathydemersal species recorded around 330 m deep, so its needs are basically the opposite of a normal home aquarium ray - cold, high pressure habitat, and not something the hobby can realistically support.
