Yes, they did. I have been feeding them a little more than normal since I got them. Unfortunately, the only petstores around here that sell these is Petsmart, and we all know what that means. I can't tell you how many very sick, almost dying frogs some have. I have had to tell more than one manager how to care for them and they had no clue, it's ridiculous. Anyway, they are getting bigger now. I started supplementing with waxworms and extra crickets and they are better.
But yes, Oscar is just plainly a fat***.

He likes to lay around and call and eat and rule the tank. But... when that lid comes off he moves faster than any of them to the top of the filter.... Sneeky, stealthy and super fast.... who knew!
