Those would be good because they aren’t to big and the foxface has means of self defensive if it does try anything. One I have that I love is a sail fin tang. I love it and also has self defense
I have done so much research I know everything about seahorses now. So I just cant find a reasonable price 30 gallon tank that is taller. Anyone who knows of a brand or one or has a link then please help me. I know you need a good filter, pump, protein skimmer, and etc... just need to find tank...
