This fish adds a unique visual appeal to my 10-gallon tank. The males are especially striking with their bright orange throats. I’ve kept one male and one female, and they seem to coexist peacefully. Water parameters are stable, and the fish is active but not overly aggressive.

I was drawn to the eel-like appearance of this fish. It fits well in my small marine setup. The coloration of the male is vivid, though the female is more muted. I’ve observed it darting between rocks and seems content in the tank.

Great addition to a nano tank. The fish is calm and doesn’t stress other inhabitants. The color change between genders is noticeable and adds variety to the tank’s look. Easy to maintain with proper water conditions.
