I've had this female festae for about 7 months now. She's been in my 55 gallon and now has been in a 80 gallon for the past few weeks. I've had her since she was 3 inches and now shes only about 4.5. She hasn't grown that much. Is this the biggest she'll get? I'm assuming she has stunted growth complex, but I don't know. She does eat.
