I got to see all the famous monsters: giant Asian freshwater stingray (Himantura chaophraya), arapaima (Arapaima gigas), giant black pacus, alligator gar (Atractosteus spatula), giant snakehead, and a variety of different marine sharks. All of these monster fish are at the Sea Life Bangkok Ocean World (formally known as Siam Ocean World). Even their tilapia are huge, like really huge. So check it out!!!
