Lillian Murray –
The fish arrived healthy and active. It has adapted well to our 40-gallon tank. We added some corals and it hasn’t shown aggression toward them. Good for intermediate reef keepers.
Emily Ellison –
We’ve had this clownfish for three months now. It’s active and curious, but not overly aggressive. The size is slightly smaller than expected, but it’s growing steadily.
Alison Buckland –
Great addition to our reef tank. It’s calm most of the time and coexists well with other fish. Water parameters stayed stable after introducing it.
