If your travel itinerary gives you choice between Siam Ocean world, Bangkok and Underwater world, Pattaya and if you are in a confusion to choose either of these place, then I would definitely suggest you to go for the Siam Ocean World at Bangkok. It offers you a great variety of underwater species to watch and enjoy. Also, the ambience at Siam Ocean world is definitely far better than what the underwater world can offer you.
As soon as you enter the Siam Ocean world, you would enjoy some of the weird and rare species of the world in small lighted glass aquariums kept in a dark place so that the little wonders are in the focus After which, you will have some of the really really fascinating coral reefs some of which have deep colors which will definitely amaze you. After enjoying some of the god’s amazing creations, you can also enjoy the glass bottom ride with huge fishes and sharks swimming right below you. The ride would be for about ten minutes with a guide explaining you something about the big swimmers
