I released one silver arowana into the reservoir !

[fotoudavid]

not sure about whether can the arowana survive or not..... but i really see a big, arowana shape fish in bukit batok nature park.... and looks a little red....

Buying a fish only to not want it later on means it was an impulse buy, which seems to be the case for some of us, when we buy a pet only to realise later that we do not have the right resources to give it a good home. While I understand your reasons behind releasing the fish, it was not the right move, given the many available options other than self-release in the name of giving the fish a "better life".

I don't really like to keep arowana, but somehow suddenly i got one baby silver arowana one day ( haha ). After 2-3 months of keeping it...

You expect a 2~3 months old baby fish which you fed everyday in a homy condition to know how to hunt for food? Nice...

Some of the most ridiculous and pretentious claims ever to be seen made by the OP of this thread.

Absolutely no care for the ecological stability; and treating fish as if they were trinkets meant only for entertainment.

Anyone like this should not be keeping fish, or pets for that matter.

Read this on PFK and remembered this thread.

I've seen almost everyday for couple of months people being catching PILE by PILE of peacock(PB and Temensis) bass in our reservoir. The supply of peacock bass is always there, the population is really humongous. These are the fish release by hobbyist and they multiply super fast. Imagine one morning i went luring and caught >100 juvenile peacock bass in one morning 1.5hr fishing until hand so tired, it was catch and release. That is really scary.

I had been observing the new Bishan River since its completion last year. Initially, it was populated (on purpose by NParks I believe) with cichlids of various variety and the river bottom was made rocky probably to emulate african lakes.
Then came the red tail catfish (I think) and the rainbow snakeheads, likely escaped from upper peirce reservoir, followed by albino suckers and goldfish colored Mayan cichlids that started appearing and increasing in numbers.
This year was more shocking. I spotted a Gar fish. A small 1 footer at first, then my wife reported a huge one, very fat and likely 2.5ft in length. I initially dismissed it as one of the smaller gar species but after seeing the huge specimen, and noting its relatively short and broad "beak", as well as its distinctive pixelated markings, I'm 90% sure its an alligator gar.

This is worrying because many young kids go into the waters daily to catch fishes and play. There is no barrier of fencing of any sort and in fact, walking onto the rocks to cross the river at several spots are encouraged when the river is not flooded.


Of course, a monster gar above a certain size would not be able to stay hidden or even survive during normal times in the shallow river, where only a few selected deep pools can be found, mostly under bridges, but the river routinely floods during rainstorms...
This picture was taken by me during a storm


there are warning systems to prevent people from venturing near the waters during rain but during flooding, very large fishes may get trapped in pools...where kids may go playing in later.

Would a large gar bite a kid?

The common motoray likely to make it there anytime since its a common fish in most reservoir now. And they are multiplying pretty fast.

The cichlids in the Kallang River at Bishan-Ang Mo Kio Park are the standard common cichlids that have become established in many urban ponds, canals, and reservoirs throughout Singapore - Midas cichlids (and assorted Central American hybrids, such as luohan), eartheaters, tilapia, and Mayan cichlid. I don't think NParks and PUB had any role in releasing these fishes, especially when it's likely that they simply dispersed down the canal from Lower Peirce Reservoir and thrived in the artificial rocky riverbed.

A friend of mine has photos of assorted fishes seen in the river, I'm not sure if his Facebook albums can be seen by all though:

Are you sure its alligator gar?
I just wiki it and found out in January 21 2011, a 1.5m alligator gar was caught at a canal in Pasir Ris by two fishermen.

1.5m?! That's big...these things can grow to 3m but it'll take 50yrs or more according to wiki.

Pretty sure, in fact, on my way out from home, I went to look again and what a stroke of luck. Wifey spotted 3 gars!
Apparently my estimate for the big guy was kinda off, probably because of how FAT he was. After looking at it long and hard, I think he's about 50cm but fat

This is the best shot I can get from the bridge...its pretty far, so the scale may make it look small. I'm very sure its a Gator Gar.

The other 2 were chase fighting

When they got closer, I ID them as a Gator gar and the other slimmer darker one as a Spotted gar. Both are about 30+cm long but much thinner as you can see.
