I recieved my new betta today in the post & the bag it was in split mid-post when i recieved it the box was soaked!!! When i opened the box the fish was jumping up & down in a empty bag, i put it into its tank and it seems fine!
As Bettas are air breathers they technically can survive being out of water so long as they are kept wet which is probably why he survived. Hope he settles in well after his bumpy ride
