Anyone tried fishing there before? I saw many flowerhorns and red devils, and also some kind of black cichlid with white patches on their cheeks, not stripey like the standard zebra tilapias. Walking cats too. All decent size, 15cm or larger. Any idea where the drain leads to or comes from?

May have some strange cichlid hybrids to ID haha

Nice sighting, the canal should logically lead to marina reservoir. More species of cichlids has become more common in canal with the conversion of the kallang basin to freshwater. I guess it can't be a bad thing.

Where is it though near to?
