Yes, Muar is in Johor state. Quite near to Malacca.
The marine LFS scene is quite active after the movie.
But sadly, it is the same scenario as in Spore - herd instinct. Their knowledge and experience are close to zero. I have seen them (LFS) set up a full reef tank (big ones) in 2 weeks, with everything in!
During my weekend trips back I would see the increasing stack of coral skeletons in their premise and tanks.
