Harry Clark –
After two years in a 100-gallon reef tank, the clown tang has grown steadily and is active in the tank. It’s aggressive but manageable with proper tank setup and hiding spots. Feeding is straightforward with daily algae wafers and marine flakes. Requires expert care and attention to tank conditions.
Piers Dowd –
This fish is a striking addition to a reef tank. It’s active and helps control algae. I had to be careful with tankmates due to its aggressive nature. The tank size and water parameters were critical to its health.
Julian Gill –
It’s a bold fish and not for beginners. I noticed it was territorial and attacked smaller fish. I added more hiding places and adjusted feeding to reduce stress. Overall, it’s a good fit for a well-established reef system.
