Okay so my poor baby hippo tang was sucked into my HOB overflow again last night even with me putting up plastic mesh. This time he got stuck in my gurgle buster and I thought that he was dead for sure but much to my surprise when I dumped him back in the main tank he started swimming and eating right away. I was shocked...he's a hardy little fella!! Well this time he got some scales scraped off on one of this sides. Will these grow back or will he always have this battle scar? I now have so much mesh on that overflow box water barely gets through!!!
