Overview
The Apollo shark minnow is a large, fast schooling fish for the surface of a very big tank. It suits a keeper with some experience and a lot of room.
Did you know
The Apollo shark minnow trails a long filament from each pelvic fin. The filaments stream behind it like pennants as it holds station in the current just under the surface.
Caring for the Apollo shark minnow
Plan on a big tank of at least 106 gal (400 L) for the Apollo shark minnow, with two meters of open length. It patrols the top and leaps, so fit a tight lid. Give it strong flow, a dark substrate and floating plants or overhanging cover it can shelter beneath.
Hold the water at 72 to 81°F (22 to 27°C) with a pH of 6.0 to 7.5. Feed floating pellets and meaty frozen foods, and it will also snap at insects at the surface.
Keep a group of five or more, because the pecking order settles in larger groups and no single fish is picked on. The Apollo shark minnow is peaceful toward tank mates too big to swallow. Anything small enough to fit its mouth is treated as food, so pair it only with robust, similar-sized companions. Its breeding has not been recorded in aquariums.
Good to know
Luciosoma setigerum is a slender, pike-shaped predator in the danio family, Danionidae, that hunts insects and small fish at the surface. Valenciennes described it in 1842. The name setigerum means bristle-bearing, after the filaments that give the fish its long-finned look.
In the wild
The Apollo shark minnow cruises the surface of large rivers across the Malay Peninsula, Borneo and Sumatra. The water there is clear to slightly tannin-stained, with a steady current.
