Claire McLean –
The Green Mandarin arrived healthy and vibrant. It has adapted well to the 30-gallon tank with proper water parameters. The coloration is striking, showing blue and green with orange accents. Requires careful feeding and stable water conditions, but it’s a rewarding addition to a reef tank.
Ava Tucker –
First time keeping a mandarin fish. It’s beautiful and active. I’ve had to adjust the diet to include more live foods. The tank needs to be well-maintained, but the fish is peaceful and doesn’t stress other tank mates.
Jack Smith –
The fish looks good in the tank, but it’s not easy to care for. I had to monitor water parameters closely and provide frequent feeding. It’s not for beginners, but it’s a stunning sight once established.
