Jane Harris –
The Regal Angel is stunning in appearance. After setting up a mature 120-gallon tank with proper rockwork and stable parameters, it adapted well. The fish shows vibrant colors and active behavior. I only recommend it to experienced marine aquarists with a well-maintained system.
Boris Davies –
Beautiful fish with striking vertical patterns. It’s peaceful and doesn’t dominate the tank. I feed it a sponge-based diet daily and keep water parameters stable. It’s a showpiece, but requires time and care to thrive.
Stewart Vance –
The fish looks impressive, but it’s not easy to keep. I had to adjust water parameters and ensure no aggressive tank mates. It took several months to settle in. Not recommended for new hobbyists.
