i want to go somewhere and be able to swim with fish--------------------- in the sea if possible. any ideas , thanks

Sometimes one can find really funny questions here...

There are a number of tour groups offering day trips to the islands off the coast from Pataya & Sattahip. Apparently one of the stops offers "swimming with the fishies".

Look at the reception counter in a hotel to find brochures for such.

The Sanctuary of Truth used to have swimming with Dolphins.

Go snorkeling or diving. There's plenty of fish in the sea.

SCUBA certification takes four days and you'll be swimming with the fishes on the third day. Alternatively, there's an option called Discover Scuba Diving which allows you to get into the water straight away under the close supervision of an instructor. Either way, there's a fantastic variety of fish to be seen out around the islands.
