Groupers & Basses- Family Serranidae. There are many
"reef" basses occupying various niches of the TWA. For the purpose of
clarity, and because they are separately identified as such, we’ll list these
by their four top genera/common name groupings.
"True" basses of the area comprise several species; most get too
big and carnivorous for home use, but two of the three most commonly offered
make outstanding aquarium fare. The Graysby, Cephalopholis cruentata (1)
is an almost dog equivalent as pet fishes go, training to "do tricks"
and coming to quickly identify with its owners. The Coney, C. fulva (1),
is a fish of many colors, coming in golds, browns, reds and bicolor phases…
always with a sprinkling of blue dots. It grows to about half the length
(10") of the larger Graysby. The Creole-fish, Paranthias furcifer
(2) is not readily recognized as a bass at all. This fish lives more in the open
waters, more like the related, smaller Anthias species.
Genus Cephalopholis:
| Cephalopholis cruentata Lacepede 1802, the Graysby.
Tropical west Atlantic. To fourteen inches maximum length. A regular
offering in the aquarium trade, though not a great beauty. Capable of
rapid color, marking changes. This one in the Bahamas. For comparison,
though it is very rarely offered in the trade, the Panamic Graysby, Cephalophlois
panamensis (Steindachner 1877), is shown. |
 
|
| Cephalopholis fulva (Linnaeus 1758), the Coney.
Tropical west Atlantic. To sixteen inches long in the wild, usually less
than half that in captivity. A hardy aquarium species that comes in three
distinct color variations: Overall red or red above, white below; Brown or
Brown above, white below, and Overall Yellow (xanthic), and changes
between these variations. Three of these color morphs all pictured below: |
Genus Epinephelus:
| Epinephelus adscensionis (Osbeck 1765), the Rock
Hind. West Atlantic. To about twenty four inches in length in the wild.
Shy, but occasionally collected for the aquarium interest. This one in the
Bahamas. |

|
| Epinephelus striatus (Bloch 1792), the Nassau
Grouper. Tropical west Atlantic. To more than three feet in the wild. A
noble game and pet-fish for large systems. This one foot juvenile in the
Bahamas. |

|
Genus Mycteroperca:
| Mycteroperca bonaci Poey 1860, the Black Grouper.
Tropical west Atlantic into the Gulf of Mexico. To more than four feet in
length. An occasional "accidental" offering out of the TWA. Adult images from the
Bahamas below. |
| Mycteroperca interstitialis (Poey 1860), the
Yellowmouth Grouper. Yet another misplaced bass in the trade. Infrequently
collected in the tropical west Atlantic as attractive juveniles, they grow
to more than thirty inches in length. Six and twelve inch individuals in
the Bahamas shown. |
 
|
| Mycteroperca phenax Jordan & Swain
1884, the Scamp. West Atlantic. To about a meter in length. One foot
specimen off of Cozumel. |

|
| Mycteroperca tigris (Valenciennes 1833), the Tiger
Grouper. Tropical west Atlantic and Gulf of Mexico. To more than three
feet in length. This handsome species is entirely piscivorous. Bahamas and
Bonaire pix. |
 
|
Genus Paranthias:
| Paranthias colonus (Valenciennes 1846),
the Pacific Creolefish. Mexico's California to Peru. To fourteen inches in
length. Occasionally sold in the aquarium trade under its own name... Here
are individuals shown during the day and resting disguised on the bottom
at night. Below, individuals of the species in the Galapagos. An
intermediate individual of four inches (young ones are all yellow), and a
mottled and commonly colored one. This is the most common bass species by
far in the Galapagos. |
 
|
Subfamily Grammistinae (or Family Grammistidae, Soapfishes), Genus
Rypticus:
| Rypticus saponaceus Gill 1861, the
Blackgill Soapfish. Eastern Pacific; Sea of Cortez to Northern Peru,
Galapagos. To thirteen inches in length.
Somber, but of an interesting shape. Occasionally imported into pet-fish
markets. In Cozumel, Mexico and Bonaire. There are eight species in this genus. |

The Dwarf Seabasses of the genus Serranus (1) are a delight to
all types of marine aquarium keepers. Most get no more than a few inches, they’re
tough and don’t hassle most types of tankmates. Four of seven members of the
genus regularly make it into the industry. Most popular are the Lantern Bass, S.
baldwini (1) and Harlequin Bass, S. tigrinus (1), with its dark
tiger-like barring. About equal in running-up are the Chalk Bass, S.
tortugarum (1), and Tobaccofish, S. tabacarius (1). The remaining
three species are likewise attractive and hardy, just not frequently available.
Ecotype: Shallows of mixed rubble, sand and reef, near the bottom.
| Serranus annularis (Gunther 1880), the Orangeback
Bass. Rocky reef areas in the tropical west Atlantic. To three and a half
inches in length. Generally occurs in pairs in the wild. Aquarium image. |

|
| Serranus baldwini (Evermann & Marsh 1899), the
Lantern Bass. Tropical West Atlantic. To three inches in length. Aquarium
photos at right, Cancun and Cozumel below. |
 
|
| Serranus tabacarius (Cuvier 1829), the Tobaccofish. A
common offering in the pet fish interest. Also from the tropical west
Atlantic. To some eight inches in length. Aquarium and Cozumel pix. |
 
|
| Serranus tigrinus (Bloch 1790), the Harlequin Bass.
Common in the wild (tropical west Atlantic) and in the aquarium trade.
Grows to almost a foot in length in the wild. A juvenile off Cozumel and
adult in St. Lucia. |
 
|
| Serranus tortugarum Longley 1935, the Chalk Bass.
Tropical west Atlantic. To three inches in length. Aquarium, Cozumel and Cancun
images. |
Reef Basslets, genus Liopropoma, are likewise beautiful,
moderately tough aquarium choices for peaceful settings. All four species found
in the TWA are striking in appearance, though only two occur in pet-fish markets
regularly. The Peppermint (aka Swissguard) Basslet, L. rubre (2) is most
often found, with the equally beautiful Candy Basslet, L. carnabi (2) a
distant second. The other two Liopropoma, the Cave Basslet (L.
mowbrayi) (2) and Wrasse Basslet (L. eukrines) (2) aren’t collected
for aquarium use. Unfortunately they are deeper water (80-200+ feet) species.
Ecotype: Caves and ledges of vertical reefs. These are very secretive fishes.
| Liopropoma rubre Poey 1861, the Peppermint Bass.
Tropical west Atlantic. To three and a half inches in length. A small, shy
beauty that adapts well to peaceful surroundings that include dark caves
to hide and sleep in. Aquarium image. |

Hamlets, genus Hypoplectrus. Whether you believe that all the
color variants of this genus represent but one widely diverging species or ten,
eleven separate ones, the Hamlets make up the third group of semi-hardy
aquarium-friendly small basses of the TWA. Most often offered is the Barred
Hamlet, H. puella (2), but it is not the greatest beauty of the group.
The iridescent Blue Hamlet, H. gemma (2), must really be seen in its full
glory in the wild to be appreciated. Other members at times available are the
Indigo (H. indigo) (2), Yellowtail (H. chlorurus) (2), and the
spectacularly gorgeous Golden Hamlet, H. gummigutta (2).
| Hypoplectrus chlorurus (Cuvier 1828), the
Yellowtail Hamlet. Western central Atlantic. To five inches overall
length. Feeds primarily on crustaceans and small fishes in the wild. Here
is one photographed off St. Lucia. |

|
| Hypoplectrus gemma Goode & Bean 1882, the Blue
Hamlet. Florida endemic in the western central Atlantic. To four inches in
length. Pictured here is a slightly washed out aquarium specimen. Wild
ones much more vibrant blue. |

|
| Hypoplectrus guttavarius (Poey 1852), the Golden
Hamlet. Spottily distributed in the tropical west Atlantic. To five inches
in length. A common Hamlet offering in the pet trade. This one
photographed in the Bahamas. |

|
| Hypoplectrus indigo (Poey 1851), the Indigo Hamlet.
Central western Atlantic in many places. To five and a half inches.
Another of the more common aquarium Hamlets. This one in the Bahamas |

|
| Hypoplectrus nigricans (Poey 1852), the Black Hamlet.
Tropical western Atlantic. To six inches in length. This photo made in the
Bahamas. |

|
| Hypoplectrus puella (Cuvier 1828), the Barred Hamlet.
To six inches overall length... Found in... the tropical west Atlantic.
One in the Cozumel, another off Bonaire. |
 
|
| Hypoplectrus unicolor (Walbaum 1792), the Butter
Hamlet. Western Atlantic; Florida. To five inches in length. Identified in
the field by distinctive caudal saddle and yellow pelvic fins. Right: Bahamas and
St. Thomas pix. Below: series in St. Thomas. |
 
|
| Hypoplectrus sp., an unknown (to me) Hamlet. This metallic
blue individual was found in Belize... near Placencia to the south there
are many of this type... More fuel to the fire that perhaps all Hamlets
are one and the same species? A beauty
nonetheless. |

|
| Hypoplectrus sp., the Tan Hamlet. Golden brown
overall color except for a bluish streak on the fore part of the pectoral
fins. St. Thomas. |
