Bought this fish for my 100-gallon tank and it’s been active and healthy after two months. It doesn’t eat much but keeps moving around, which adds energy to the tank. Good for a predatory species that doesn’t dominate the group.

The fish looks striking with its dark charcoal color. It’s more active than expected and seems to enjoy open areas. Needs a large tank, but worth it for the visual impact.

Very sturdy and calm in a well-maintained setup. I paired it with larger community fish and it coexists without aggression. Great for aquarists who want a unique and bold species.
