Lionfish and Niger Trigger

What's the minimum size tank I would need for a black volitan lionfish and a niger trigger?

 

Have a read here... https://www.fishlore.com/Profiles_Lionfish.htm
They're such beautiful fish!

 

Would a 75 gallon-80 gallon work because volitans lionfish grow 15" and niger triggers grow 16"

 

I should think that will be fine - I would say minumum of 55 gallons but obviously the bigger the better!

Best of luck!

 

I wouldn't keep a trigger with a lionfish. They can both be aggressive but the triggers more so...

 

Well the other day I was at a pet store and I saw a red volitan lionfish in the same tank with a picasso trigger. I'd think it would be a bad idea to put a lionfish with a very aggressive trigger such as an undulate trigger.
