Donna Grant –
The Keyhole Angelfish is a striking addition to my 50-gallon reef tank. It has been active and colorful since arrival. I’ve kept it with hard corals and no major issues so far. Needs a bit of space and stable water parameters, but overall a good choice for intermediate reef keepers.
Evan Young –
It’s beautiful and active. I noticed it occasionally touches soft corals, so I’ve moved them slightly away. It’s not aggressive, just curious. Feeding is easy and it eats well. Good for a mid-sized tank with proper setup.
Yvonne Reid –
The fish arrived healthy and has settled in well. I’ve had to monitor its behavior closely, especially around smaller polyps. It’s not a perfect fit for a mixed reef, but it adds visual interest and is manageable with care.
