Yep thanks, he healed up nicely and I think he's actually maybe closer to 15-16". Now my other fish is taking turns with a damaged eye. the big gatf probably hit his eye on the wave maker and there's a white spot. Doing extra water changes this week to see if the damage heals up. Two of my blackberry silver dollars recently had bleeding eye probably from the Vatf and now they are in quarantine tanks waiting to be given to a friends masheer 3m tank. Eyes are definitely a big weak spot.
