Please see my post , I can also answer anyone’s questions

How do the fox faces act towards each other? You have the same size tank I am getting in June and I’ve never had any luck keeping any rabbit fish but a one spot fox face so I would like to keep a few

We have two Fiji fox faces two regular fox faces and two rabbit fish. Not including all the 51 other fish lol. Couple quarrels but fine overall
