Violet goby
Gobioides broussonnetii
This is the long, eel-y "dragon goby" you see at shops sometimes-looks scary with that toothy face, but it's actually a chill mud-and-sand sifter. In nature it hangs around muddy estuaries and river mouths, and that's the trick in aquariums too: soft sand, brackish-ish water, and food it can actually find (they're not great hunters).
Weed cardinalfish
Foa brachygramma
This is a tiny Hawaiian cardinalfish that hangs around sheltered shallows - think seagrass, algae, and rubble - and it even wanders into brackish and sometimes fresh water. Its vibe is classic cardinalfish: mellow, a little shy, and way more interesting once the lights go down. Also cool trivia: the males mouthbrood the eggs.
Wu's goby
Wuhanlinigobius polylepis
This is a tiny mangrove-and-mudflat goby from the western Pacific that spends its time on the bottom, often in really shallow brackish areas. The cool part is how "muddy" its lifestyle is - it gets found in puddles on exposed mud at low tide and can even be partly buried, so it appreciates a soft substrate and lots of cover if you ever try one.
X-ray tetra
Pristella maxillaris
This is that little see-through tetra where you can kinda make out the spine inside the body, and then it tops it off with those sharp black/yellow/white fin markings and a reddish tail. Super chill schooling fish, and it's one of those rare tetras that doesn't freak out if your water isn't "perfect Amazon blackwater" 24/7.
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.
Zamboanga priapiumfish
Neostethus zamboangae
Neostethus zamboangae is a tiny priapiumfish (family Phallostethidae) native to the Philippines, known for males having a reproductive/copulatory organ located under the chin/throat region; it occurs in freshwater and brackish habitats.
