Snappers, Family Lutjanidae

To: part II, part III

By Bob Fenner

Lutjanus quinquelineatus  

     Amongst the "personality" fishes for marine aquariums, few can match some of the snapper family. These animals can be hand tamed, and kept for a very long time... if you have the space.

The snappers and their allies, the fusiliers are good additions for "fish-only" marine systems, who, though bold eaters, only require a darkened space to call their own.

Classification, Favored Species:

All told there are twenty one genera and some hundred seven described species of snappers. The family Lutjanidae is further split up by some taxonomists into five subfamilies; in recent schemes including the planktivorous family/subfamily of fusiliers, Caesionidae/Caesioninae.

Take a look at a "typical" snapper; they all have a similar body plan; a continuous (or shallowly notched) dorsal fin with 9-12 spines and 9-18 soft rays; an anal fin of three spines and 7-11 soft rays. Notice the origin of the pelvic fins; they're inserted just behind the pectoral base, granting the fish good turning and hovering control.

How 'bout the mouth? With a common name like snapper, you'd assume theirs would be large, and you'd be right. Snapper mouths are easy to spot, being terminal, most with enlarged canine teeth, and a distinctive arrangement of jaw-bones. Technically the maxilla slips beneath the preorbital bone when the mouth is closed and the supramaxilla is absent; it must appear like a landing ramp to other aquatics as well, right up to the time they're inhaled.

Natural and Introduced Range

Snappers are tropical and subtropical in the Pacific, Atlantic and Indian oceans; a few are estuarine to entirely freshwater (Lutjanus fuscescens, Lutjanus goldiei, Lutjanus maxweberi), though these aren't the ones typically sold as "freshwater snappers". Snappers are important food and game fishes, and several species have been introduced into non-native waters.

Size:

 Small species get to about half a foot, largest ones attain a yard in length. Small species get to about half a foot, largest ones attain a yard in length.

Favorite Aquarium Snapper Species: 

The following Lutjanids are amongst those most often encountered in the pet-fish hobby, but except for the one warned against below, the whole family does well in "standard" aquarium conditions; as long as their tank is big enough. Do look for the smaller species if your aquarium volume is limited.

The Emperor Snapper, Lutjanus sebae (Cuvier 1816), is a real beauty as a juvenile, but beware; it gets to be a real honker... more than three feet long in the wild! Another good reason to under- and infrequently feed an emperor is that their gorgeous color fades with growing size. Here is a juvenile in an urchin in N. Sulawesi, one of four inches in captivity, and an adult in Australian waters.

In good stead with the Emperor and catch all "miscellaneous" snappers from the Indo-Pacific are the threadfin snappers, Symphorichthys spilurus (Gunther 1874) (aka the Majestic Snapper) and Symphorus nematophorus (Bleeker 1860) (the Blue-Lined Snapper) which must be seen in person to be fully appreciated. These two have golden yellow bodies flanked by bright blue horizontal bars, two vertical black head bands and a dark caudal spot. They look touchy but are as tough as the best snappers. To two and three feet maximum length respectively. Here are gorgeous juvenile and adult Majestics in captivity.

Standard offerings from the Caribbean include the Dog Snapper, Lutjanus jocu (Bloch & Schneider 1801), the appropriate color-named Mahogany Snapper, Lutjanus mahogoni, and yellow-tailed snapper, Ocyurus chrysurus; the last being one of the most popular snappers for aquarium use for its beauty, more peaceful nature, and slower growth. Less often seen from the western Atlantic are the Mutton Snapper, Lutjanus analis, and Schoolmaster, Lutjanus apodus; feed these last two sparingly, they get big, fast.
