Lisa Wright –
This fish is quite active and territorial. I kept it in a 150-gallon tank with a few large cichlids. It grows fast and requires a stable environment. The water parameters stayed within range with proper maintenance. A good choice for experienced aquarists.
Anthony Tucker –
The fish arrived healthy and active. I noticed it was quite aggressive toward smaller fish, so I made sure to keep only larger, mature cichlids. It’s a striking fish and adds a lot of energy to the tank.
Grace May –
It’s a bold fish and needs a large tank. I had to adjust my tank setup to accommodate its size and behavior. Not recommended for beginners due to aggression and space needs.
