Bicolor blenny in my tank has a ton of personality. They watch you as much as you watch them. Same with a lot of gobies. And as always, clowns are usually front and center.
Tailspot blenny had tons of personality was such a goofball, gobies, Multi band pipefish had very dog like personalities but don't fit into the small category.
Awesome! Thanks everyone! I just brought home my first ever saltwater fish...a blue spotted puffer and a fancy white clown. Will go through the qt then will add a couple more...off this list! Thanks for the info guys!
My yellow eyed kole tang is prolly my fav non coral critter in my tank. He's very inquisitive and since my tank is sitting where I walk by several times a day he follows me around as I walk passed and if I'm standing at the front of the tank he's front and center.
Forget trying to take a pic of anything in the tank with out getting a few close ups of him as well.
