Morphology: Dorsal spines (total): 7; Dorsal soft rays (total): 27-32; Anal spines: 1; Anal soft rays: 28-31 Biology: Found over hard, open bottoms at the bases of reefs and over sand and rubble patches. Often in pairs. Feeds on zooplankton, especially copepods and crustacean larvae. Darts into a hole when alarmed. Aquarium Care: This hardy species readily acclimates to captive life. Provide the Elegant Firefish with plenty of hiding spots, and a substrate. This is the most aggressive of firefishes, and should be kept singly or in male-female pairs. More belligerent fish species may cause the Elegant Firefish to hide constantly, resulting in starvation. Feed an enriched and varied diet, as this species is prone to fade in coloration. Meaty fare, including shaved or finely chopped fresh or frozen seafood, frozen perparations for carnivores, frozen and live bring shrimp and nysid shrimp. Feeds mostly on prey suspended in the water column, and a refugium may be beneficial. Keep tank and small openings and crevices covered, as it is prone to jump. <br /><br />1 comment mojoreef Sat, 01 Jan 2005 12:19:49 -0600 Blue Gudgeon http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=734&title=blue-gudgeon&cat=521 <a href="http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=734&amp;title=blue-gudgeon&amp;cat=521"><img title="41Ptereleotris_microlepis.jpg" border="0" src="http://www.reeffrontiers.com/photos_fish/data/521/thumbs/41Ptereleotris_microlepis.jpg" alt="41Ptereleotris_microlepis.jpg" /></a><br /><br />by: mojoreef<br /><br />Description: Scientific Name: Ptereleotris microlepis Common Names: Blue Gudgeon, Green Dartfish, Green Gudgeon Goby, Pearly Gudgeon Goby Max. size: 13.0 cm TL (male/unsexed) Environment: reef-associated; marine Distribution: Indo-Pacific: Red Sea to the Line and Tuamoto islands, north to the Ryukyu Islands, south to the southern Great Barrier Reef; Mariana and Marshall islands in Micronesia.

Usually in pairs as adults and in small aggregations as juveniles. Feeds on zooplankton while hovering 1 to 2 m above the bottom. Swims away from danger rather than retreat to its burrow. Aquarium Care: Provide plenty of swimming space, sand substrate for burrowing, loose rubble. May jump out of the tank, so covering even the smallest crevices and openings for prevention. It will rarely become aggressive towards other fish. Feeds on zooplankton, and a refugium would be beneficial. Live foods may be needed to induce a feeding response and accept captive foods. mojoreef Sat, 01 Jan 2005 12:19:49 -0600 Curious Wormfish http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=730&title=curious-wormfish&cat=521 <a href="http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=730&amp;title=curious-wormfish&amp;cat=521"><img title="41Gucur_u1.jpg" border="0" src="http://www.reeffrontiers.com/photos_fish/data/521/thumbs/41Gucur_u1.jpg" alt="41Gucur_u1.jpg" /></a><br /><br />by: mojoreef<br /><br />Description: Scientific Name: Gunnellichthys curiosus Max. size: 11.5 cm TL (male/unsexed) Environment: reef-associated; marine Distribution: Indo-Pacific: Seychelles and Mauritius to the Hawaiian and Society islands. Morphology: Dorsal spines (total): 20-21; Dorsal soft rays (total): 40-42; Anal soft rays: 38-40 Biology: Found over sand or mud bottoms and take refuge in burrows. Solitary or paired. Feeds primarily on benthic and pelagic crustaceans Aquarium Care: Requires a very peaceful aquarium. Provide plenty of live rock for hiding, a deep soft sand bed for burrowing, and a refugium. This species is very poorly suited for community aquarium life. They are easily intimidated into not eating. Some say that they are more difficult to keep than Mandarinfishes, Seahorses or their Firefish (Microdesmid) kin. Also, it has been indicated that they are so shy, in fact, if this fish shares the tank with one Wrasse, Damselfish, Clownfish or Tang, it will perish, even without aggression from its tankmates. House in a tank with ultra slow and ultra peaceful tankmates. Feed zooplankton substitutes. mojoreef Sat, 01 Jan 2005 12:19:48 -0600 Yellowstripe Wormfish http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=731&title=yellowstripe-wormfish&cat=521 <a href="http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=731&amp;title=yellowstripe-wormfish&amp;cat=521"><img title="41Gunnellichthys_viridescens.jpg" border="0" src="http://www.reeffrontiers.com/photos_fish/data/521/thumbs/41Gunnellichthys_viridescens.jpg" alt="41Gunnellichthys_viridescens.jpg" /></a><br /><br />by: mojoreef<br /><br />Description: Scientific Name: Gunnellichthys viridescens Max. size: 7.2 cm TL (male/unsexed) Environment: reef-associated; marine; depth range 1 - 21 m Distribution: Indo-Pacific: Seychelles, Maldives, and the Great Barrier Reef; Carolines and Marshalls in Micronesia.

Yellowish to greenish gray in color; lower half of eye to ventral of chin nearly enclosed by a broad blue-edged dark red to purple area; opercle with 2 diagonal bright blue bands; pectoral fin base with an orange-red bar broadly bordered with bright blue. Chin barbel followed by a median longitudinal fold. Fins yellowish; 2nd dorsal a median longitudinal row of blue spots. Biology: This schooling species inhabits exposed seaward reefs in relatively shallow water, over hard bottoms. Usually many individuals occupy the same refuge. Aquarium Care: This peaceful species is highly disease resistant. The Zebra Dartfish does best when kept with peaceful tankmates, such as other dart gobies, and plenty of places to hide (including sandy substrates). It will bury in finer sandbeds at night or when threatened. Best to keep in pairs or small groups. It will often hide for a week or two, after introduction. Once acclimated, it will swim about in the tank. Cover the tank and all small crevices and openings, as this fish is prone to jumping. Provide a varied meaty diet, including enriched brine, mysis shrimp, finely chopped fish or shrimp flesh, with one or two feedings per day. A productive refugium may also be beneficial. This species is an open water swimmer and needs lots of open swimming space, but is shy and needs spots close by to hide in. mojoreef Sat, 01 Jan 2005 12:04:08 -0600 Firefish http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=722&title=firefish&cat=521 <a href="http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=722&amp;title=firefish&amp;cat=521"><img title="41Nemateleotris_magnifica.jpg" border="0" src="http://www.reeffrontiers.com/photos_fish/data/521/thumbs/41Nemateleotris_magnifica.jpg" alt="41Nemateleotris_magnifica.jpg" /></a><br /><br />by: mojoreef<br /><br />Description: Scientific Name: Nemateleotris magnifica Common Names: Firefish, Fire Goby, Fire Dartfish, Magnificent Dartfish Max. size: 9.0 cm TL (male/unsexed) Environment: reef-associated; marine; depth range 6 - 70 m Distribution: Indo-Pacific: East Africa to the Hawaiian, Marquesan and Pitcairn islands, north to the Ryukyu Islands, south to New Caledonia and the Austral Islands; throughout Micronesia. Morphology: Dorsal spines (total): 7; Dorsal soft rays (total): 28-32; Anal spines: 1; Anal soft rays: 27-30 Biology: Inhabits upper portions of outer reef slopes. Hovers above the bottom, facing the current to feed on zooplankton, copepods, and crustacean larvae. Several individuals may share the same hole (especially juveniles). Has a habit of flicking its pennant-like first dorsal fin back and forth. Aquarium Care: This hardy and shy species does best when kept with passive tankmates. If kept with more aggressive fish, it may hide and not eat. Keep singly, unless a very large tank, or a male-female pair is obtained. If kept in groups, one individual will usually begin to chase the others, until they are killed. Provide coral rubble and suitable hiding spots. This species is a jumper, so care should be taken in covering the tank, small openings, and crevices. Feed a varied diet, to help prevent the colors from fading. Feed meaty fare, including shaved or finely chopped fresh or frozen seafood, frozen preparations fro carnivores, frozen and live brine shrimp, and mysid shrimp. A popular species choice in the hobby. <br /><br />2 comments mojoreef Sat, 01 Jan 2005 12:04:07 -0600 Onespot Wormfish http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=723&title=onespot-wormfish&cat=521 <a href="http://www.reeffrontiers.com/photos_fish/showphoto.php?photo=723&amp;title=onespot-wormfish&amp;cat=521"><img title="41Gunnellichthys_monostigma.jpg" border="0" src="http://www.reeffrontiers.com/photos_fish/data/521/thumbs/41Gunnellichthys_monostigma.jpg" alt="41Gunnellichthys_monostigma.jpg" /></a><br /><br />by: mojoreef<br /><br />Description: Scientific Name: Gunnellichthys monostigma Max. size: 11.0 cm TL (male/unsexed) Environment: reef-associated; marine; depth range 1 - 20 m Distribution: Indo-Pacific: East Africa to Marquesan and Society islands, north to Ryukyu Islands, south to the southern Great Barrier Reef.

They tend to form large, though diffuse, colonies; may be due to a propensity to aggregate or may be a result of the ecological requirements for the species (for which type of substratum, current pattern, and water depth among the most important) which restrict the areas of settlement of the postlarvae. Aquarium Care: This species does best when provided plenty of hiding places, and peaceful tankmates. The Monoptera Dartfish is uncommon and modest. They require similar care as other members of the Ptereleotris genus. Cover the tank, small openings, and crevices, as Ptereleotris spp. can jump out of an aquarium. Feeds on zooplankton, so a refugium may be beneficial. Feed a variety of meaty foods, such as haved or finely chopped fresh or frozen seafood, frozen preparations for carnivores, frozen and live brind shrimp, and mysid shrimp. Favors rocky substrates, and large colonies of conspecifics. mojoreef Sat, 01 Jan 2005 12:04:06 -0600
