The lionfish arrived healthy and looks vibrant. I’ve maintained a 100-gallon tank with proper water parameters, and it has been active and colorful since setup. It’s semi-aggressive, so I keep it away from smaller fish, but it’s a great addition to my reef tank with caution.
Rachel Watson –
It’s a striking fish with bold colors. I’ve kept it for about six months now and it’s adapted well to the tank conditions. The water parameters are critical, and I’ve been monitoring them closely. It’s not overly aggressive, but it does chase smaller fish occasionally.
