I personally do not think these arowanas should not be released in the wild or in reservoirs as these are not native to Singapore. They could be donated to the Singapore Zoo especially so when the River Safari (a river themed wildlife park) has recently opened. This would be a more humane way of disposing your pets rather than to dump them into the wild and upset the ecological balance.
