Red Firefish Goby (Nemateleotris magnifica)
The Red Firefish Goby requires a 10 gallon or larger aquarium with plenty of rockwork for hiding and a lid to prevent it from escaping. It will rarely become aggressive towards other fish, but is territorial and will fight with its own kind unless housed in a 100 gallon or larger aquarium or as a mated pair. It feeds primarily on prey suspended in the water column, and will also pick food from the substrate or live rock. A diet of frozen or live brine shrimp, live blood worms, and mysis shrimp is recommended. For vibrant coloration, feed a vitamin-enriched diet.

The Red Firefish Goby is a striking addition to my 20-gallon tank. It’s active and colorful, and it doesn’t bother other fish. I feed it brine shrimp and blood worms daily, and its colors stay bright with the vitamin-enriched food.

I kept one in a 15-gallon tank with live rock. It hides well and seems content. I’ve noticed it’s more peaceful than expected, though I’d avoid keeping multiple individuals.

Great fish for a beginner aquarist. It’s not aggressive and stays in its hiding spots. I feed it mysis shrimp twice a week and it’s always active and lively.
