Received the Atlantic Achilles Gold Coin Tang in good condition. It’s active and shows vibrant coloration. The tank is now 150 gallons and has been stable for several months. It’s semi-aggressive but not overly territorial when given space. A great addition to a reef setup.
Claire Black –
The fish arrived healthy and has been thriving in our 150-gallon tank. It’s not the most docile, but it’s manageable with proper tank setup. We’ve added some larger fish that don’t seem to provoke it. Color is bright and it’s active during the day.

This tang is a standout in our aquarium. It’s visually striking with its gold coin-like appearance. We’ve maintained a stable environment and it’s grown steadily since arrival. The care level is intermediate, and we’ve followed all guidelines for feeding and tank maintenance.
