Evermann's cardinalfish
Zapogon evermanni
This is a reef cave-dwelling cardinalfish that likes to hang way back in the shadows and will even cruise the cave ceilings upside-down, which is super fun to watch. It is more of a dusk/night kind of fish, usually seen alone or in pairs, and it is a mouthbrooder like a lot of cardinalfish.
Evezard's loach
Indoreonectes evezardi
This small Indian brook/stone loach occurs in stream habitats in India (Western Ghats and Satpura range). The species includes cave-adapted forms (e.g., reported from Kotumsar Cave) that may show reduced pigmentation and regressed eyes.
Exquisite sand-goby
Favonigobius exquisitus
This little sand-goby is a bottom-hugger from Aussie estuaries that likes to hang out on sandy flats (sometimes right in seagrass). Its whole vibe is "blend in, perch, and pounce" - a neat goby if you are into naturalistic brackish setups and watching tiny ambush-predator behavior.
Exquisite wrasse
Cirrhilabrus exquisitus
This is one of those fairy wrasses that looks like it was painted with highlighters - males can shift through greens, reds, blues, and purples depending on mood and whether they are showing off. In a reef tank its usually out and cruising the water column, grabbing tiny meaty foods, and doing little display flare-ups at its own reflection or other wrasses. Biggest real-world gotcha is they are jumpers, so a tight lid or mesh top is basically mandatory.
Eyespot pufferfish (Figure-8 puffer)
Dichotomyctere ocellatus
This is the little "figure-8" puffer with the yellow-green squiggles and the two bold eyespots near the tail-tons of personality in a small body. They're basically snail-hunting machines with a curious, interactive vibe, but they can be spicy with their own kind, so you plan the tank around that.
