I had one that was 5in. lived for a month then died. I had some buddies have the same thing happen. Tell me everything there is to keep one alive. As far as I know I had everything right. It ate mostly feeders and cut-up nightcrawlers. I had the temp at 81-82F. 90 Gallon tank with 3 african pikes the same size and orange pike cichlid same size. Two aquaclear 110 and eheim professional 2 canister 2028. Water change once a week. What quality of water do they prefer or did my pike stress him out after a month???
