Tengalan in Chinese is 丁加兰 (ding Jia lan in Mandarin, Ding Ga Lan in Cantonese). It taste very nice, but it has insane amount of bones. You need to be very careful when you're eating it. Same like sultan jelawat fish. Usually my relatives living there will buy from the Malay fishermans, only rm30-40 for huge 1.5-2kg fish.

Regarding Soon Hock price, the price selling in the wet market is quite cheap. In restaurants it's not very cheap as well like in KL/Selangor.

If you travel to Lenggong, you can PM me for some restaurant recommendations and the local specialties. The local cili padi sauce (MK Brand - owned by my relative) is miles better than Kg. Koh, and there's a nice roti canai stall selling there in the morning. For Chinese food Chat Sook Restaurant is great and rarely mentioned in newspapers and websites because it's relatively new (opened in the past few years) but the chef is one of the best in Lenggong since he was trained by his father, one of the legendary chefs in Lenggong's golden age where even Hong Kong celebrities would visit the town and when Lenggong is a major town in Perak.
