Changed days then!! Is the old oil platform still at the "mouth" of the river? The one you could walk along the pier and fish off of?
Mostly caught snapper and cats off it, but going down the legs onto the lower structure and fishing a deadbait often produced nice grouper. Even managed a 20lb Guitar fish off of it.
Funny you mention Gouramis. I used to catch Three Spot Gouramis, Siamese Fighters, various types of Barb and Loach, Bumblebee Gobies, Sumatran Clown Fish and various other "Aquarium" fish and sell them to a shop in Seria. Useful pocket money for a kid on his school holidays
Later on when I started to dive, I had a 7 foot tank in the car porch that I stocked with various marine fish, all hand caught. I would get them at the start of the 8 week holiday, and return them at the end before heading back to the UK and school.
I miss those days lol. Whilst I had an amazing childhood out there, I do wish I was a bit older and wiser as I would have made more of my time there.
