Yes, I have a species only tank with two green spotted puffers and a softy reef. While they are very cool fish I don't know if I would call them personable because they startle so easily and panic. But I love watching them all the same and hand feed the one who will come up to the top.
Mine and my friend's always follow you when you walk by the tank. How long have you had yours and how often are you near the tank? Also, do you have an automated feed system or do it yourself?
