Helfrichi Firefish Goby (Nemateleotris helfrichi)
Max Size: 2 1/2 inches
Reef Compatible: Yes
Minimum Tank Size: 20 gallons
The Helfrichi's Firefish, also referred to as Helfrich's Dartfish, displays a yellow head with a purple forehead, while its body exhibits a combination of purple and white hues. To keep this fish, one must provide an aquarium of 20 gallons or more, including plenty of loose coral rubble as part of the aquascape and a secure lid to prevent it from jumping out of the tank. Though it seldom displays aggression towards other fish, it is territorial and will attack its own species, except for its mate.
This fish mainly feeds on prey in the water column, but it will also consume food from the substrate. Its diet should consist of a variety of shaved or chopped seafood, vitamin-enriched brine shrimp, and mysis shrimp.
