Frequently Asked Questions

Is the kole tang reef safe?

Yes, and it’s one of the best algae-grazing tangs for a reef, eating film algae and detritus off rocks with its bristle-like teeth. It won’t harm corals or inverts.

What size tank does a kole tang need?

At least 70 to 90 gallons. It stays smaller than many tangs (about 6 inches) and is one of the more peaceful, making it a great reef workhorse.

Is the kole tang good for beginners?

It’s one of the hardier, more peaceful tangs, so yes for someone with an appropriately sized tank. It’s less aggressive than the yellow or powder blue tang.
