Red Sailfin Goby – Exallias brevis

Overview:
The Red Sailfin Goby, also called the Leopard Blenny, is actually a blenny species despite its trade name. Recognizable for its elongated body, spotted reddish-brown markings, and tall sail-like dorsal fin, this fish is both striking and unusual. It spends much of its time perched on rockwork or coral, using its comb-like teeth to graze.

Origin:
Widespread throughout the Indo-Pacific, particularly in coral-rich reefs from East Africa to Hawaii.

Feeding:
Specialized corallivore – primarily feeds on live coral polyps in the wild. In captivity, it is very difficult to maintain, as it rarely accepts prepared foods. Some individuals may pick at frozen mysis, brine shrimp, or algae-based foods, but survival without coral polyps is often poor.

Tank Mates:
Best kept alone or with peaceful reef fish. Not suitable for tanks with prized corals, as it will nip and feed on them. Avoid keeping with aggressive species that may outcompete it for hiding spots.

Aggression:
Low. Generally peaceful toward other fish but territorial with its own kind.

Experience Level:
Expert only. This fish is not recommended for most aquarists due to its coral-eating habits and poor adaptation to captive diets. Best kept only by highly experienced reef keepers with access to natural coral food sources.

Water Parameters:

• Temperature: 74–80°F (23–27°C)

• pH: 8.1–8.4

• Salinity: 1.020–1.025

• Minimum Tank Size: 50 gallons with ample live rock and corals

The Red Sailfin Goby (Exallias brevis) is a rarely kept, coral-dependent species more often admired in the wild than in aquariums. Its beauty comes with very demanding care requirements, making it suitable only for advanced marine specialists.
