Normally I try not to be so superstitious but I recently bought 100 gallon tank from an old man. His son told me they used to have a really big arowana but it died years ago. They started to have bad luck for 3 years since its dead lol. I also have my own experience with this fish. Back then when I first got into this hobby, I got myself a very nice aro and it died the next day because I didn't have a heater (i know I was such a hurry). Anyway, 3 days after I got a speeding ticket and few other bad things have happened that time. So....I'm wondering if any of you also have a bad luck after your fish dead ?
