    So I know they get pretty big, but mine won't stop eating. Should he go on the time out rock? [lol I know it's stupid] or should I just let him keep eating?
    He isn't a picky eater at all. He just gobbles anything up in front of him.

    This would depend on the type of Blenny; they have a range of 3-6 inches depending on the species.

    These guys get up to 5-6 inches...didn't you say you have a 15g?

    That is much to small for these guys based on just length/size alone in addition to space

    4-6" is common size for them. I wouldn't keep them in anything smaller than a 30gal. Make sure you have plenty of algae for them. If it becomes insufficient I'd supplement with a quality algae sheet otherwise they'll starve to death.

    lol. Fish store people know less about tanks than I do. He's really full and pretty small and happy, if he get's real big, like real big, I'll look for rehoming

    for some reason mine doesn't eat algae, he eats pellets and stuff, well he eats algae, he also eats the other stuff. I'm not sure this is a lawn mower. Pet store people know less than I do
