tips for reducing aggression in tangs

My Yellow Tang keeps chasing my Blue Tang around the tank. It's a 75-gallon setup with plenty of live rock, but the aggression hasn't stopped. Anyone got tips to calm them down?

I've had similar issues with my Powder Blue Tang. Adding more hiding spots helped, but it took a while for them to settle. How often are you feeding them?

Tangs are territorial, especially in smaller tanks. A 75-gallon is on the tight side for two tangs. Try rearranging the rocks to disrupt territories and increase feedings to twice a day with nori clips. Also, check your water params, high nitrates can stress them out.

Yep, this is solid advice. I'd also add a mirror to the side of the tank temporarily. It distracts the aggressive one by making it think there's another tang.

My Purple Tang was a bully until I added a bigger tankmate. Sometimes a bigger fish can cut the aggression. Just make sure it's not another tang, or you're gonna have a bigger problem.

Aggression in tangs is often about space. A 75-gallon is minimal for one tang, let alone two. Consider upgrading or rehoming one if the behavior doesn't improve.

I don't have tangs, but my clownfish were aggressive until I added more rockwork. Maybe try that?

Thanks for the advice, everyone. I'll try rearranging the rocks and upping the feedings first. If that doesn't work, I might look into a bigger tank.

Good plan. Let us know how it goes. Sometimes it just takes time for them to establish a pecking order.

Also, make sure your water quality is spot on. Tangs are sensitive to poor conditions, which can make aggression worse. Test for ammonia, nitrite, and nitrate regularly.
