I tried catching some of these while I was 32 Fishing, and was only able to land 1 Ca Cuong using up 7 stacks of Little Worms with my Lu Shang's Rod. At my level, they put up a very tough and noticable fight, and you can sense when you've caught one, but I wasn't able to drain their HP bar quickly enough to land them. They do bite often, and with a little practice and more skill, they should be fairly easy to catch. Also, I was catching lots of Brass Loaches with the same setup, and in the same pools. -- ‡~ÐEMÅNTÏ~‡of Carbuncle 17:42, 3 May 2008 (UTC)
Had a BST ask me about these today and decided to give the fishing spot a whirl. Grauberg (S) page lists it as 69 but I found this to be incorrect, as the discovoring fisher must've not selected the right rod for this spot as I had no problems at all.
Halcyon Rod, Little Worm, Grauberg (S) Witchfire Glen Pools, lvl 36 fishing, no fishing gear. 2 hour fishing results;
16 Cu Cuong, tough fishing (Giving skillups of 0.1 - 0.2). 30 Brass Loach, fast stamina loss, twitchy rod (Giving fewer skillups of 0.1 - 0.2). 1 Black Eel (from stream, not ponds). 1 lost catch (bad timing). 1 line break (Your fairly sure out dont have enough skill). Rusty leggings (bleh) x5. 21 monster (caught a few then released, Easy Prey crabs and bugs to 62). Note: Storming from 10:00 - 20:00 seems to generate the most Cu cuong (Just a theroy right now).
Further testing will be done later for storming theory. --TheLetterD 11:49, 11 September 2008 (UTC)
