LMAO Poor old Jack got Pearl Harbored, did he? Never did go for the piranhas or cichlids, myself. After coming home from a long day, the last thing I want to do is kit up in a chain-mail glove and shove my arm into a tank full of aquatic Bloods and Crips, because two of them got territorial over the last feeder goldfish. I only use isolation tanks for new fish and as an infirmary for sick ones. I don't have time to run one as a supermax cell block. LOL
