In a medium saucepan, bring the water to a gentle boil over medium heat, and then stir in the curry paste, green beans, bamboo shoots, and pineapple. Stir well and simmer 5 minutes.
Add the fish chunks, fish sauce, tamarind liquid, and palm sugar, and cook 3 to 5 minutes, until fish is cooked through. Remove from heat and transfer to a serving bowl. Stir in the lime juice, and serve hot
