I was raising it in a 20gal under one of my 125gal tanks.. It came in around the size of my pinky and it was a beast. unfortunately I hurt my back Monday and left the lid open on his tank so I wouldnt have to bend to feed him and he jumped out. He was up to about 4.5 inches. I took his poor little dried out body and dropped it in the 125 above his tank and my 11in Dorado ate him like some oversized beef jerky. Between the shifts I lost and loosing my baby brokopndo, this is becpming and expensive back injury. At least m bigger brokopondo is coloring up and becoming the show piece I hoped it would be, the gold is amazing....
