Eregli minnow
Garra kemali
Garra kemali is a tiny Turkish Garra that hangs close to the bottom and spends a lot of time grazing surfaces for edible bits. It comes from marshes and lakes rather than the typical fast riffles people associate with many other Garra, and its wild populations are considered endangered, so its story is more conservation-focused than aquarium-trade focused.
Eriarcha rhamdella
Rhamdella eriarcha
Rhamdella eriarcha is a shy little South American three-barbeled catfish (Heptapteridae) that spends a lot of time tucked under wood and cruising the bottom after dark. It gets a lot bigger than most people expect for a "small" catfish, so think more "subtle nocturnal predator" than "tiny cleanup fish".
Eurasian Minnow (Common Minnow)
Phoxinus phoxinus
Phoxinus phoxinus is a small, fast-swimming minnow associated with cool, well-oxygenated waters. It is a gregarious shoaling fish; males intensify in colour during breeding. Note: the name P. phoxinus has historically been applied broadly across Eurasia, but the group is now treated as a species complex in which true P. phoxinus may be restricted to parts of Western Europe.
European gudgeon
Gobio gobio
The European gudgeon is a small bottom-dwelling cyprinid with a slender body, sandy-brown mottling, and distinct barbels at the corners of the mouth used to locate food in the substrate. It is an active schooling fish that prefers well-oxygenated water and a sand or fine-gravel bottom, often resting on the substrate between foraging bouts. Best kept in cool, river-style aquariums with moderate flow rather than warm tropical setups.
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.
Falcate snailfish
Careproctus cypselurus
Careproctus cypselurus (falcate snailfish) is a marine, bathydemersal snailfish (Liparidae) from the North Pacific (off Japan and from the Sea of Okhotsk to off Washington, USA), recorded from deep water (about 35–1993 m). It is not a typical aquarium species due to its deep-sea/coldwater ecology and specialized life-support needs.
Faufré noir
Grammonus ater
A small Mediterranean cave brotula that slips out at night to hunt and tucks deep into crevices by day. It has an eel-like body with one long fin from back to tail and even gives birth to live young. Super cool if you are into cryptic species, but it is rarely seen in the trade.
Faustino's lanternfish
Diaphus faustinoi
Diaphus faustinoi is a marine lanternfish (family Myctophidae) reported from the Philippines and the western-central Pacific. Like other myctophids it is a deep/mesopelagic open-ocean fish with photophores and diel vertical migration behavior, and it is not a practical home-aquarium species.
Feathered river-garfish
Zenarchopterus dispar
Zenarchopterus dispar is a surface-hanging halfbeak from mangroves and sheltered bays, with that classic long lower jaw for snapping up insects and other floaty foods. Males get those funky elongated fin rays (the "feathered" look), and they are livebearers, so once they settle in you can occasionally get surprise babies. Biggest thing with this fish is giving it calm water up top, room to cruise, and a tight lid because halfbeaks can rocket-jump.
