What's wrong with piranhas.

[Snoke FIsh]

For context I live in Singapore where most fish species are allowed to be sold except protected species and PIRANHAS. I know a private owned pond (available to the public) with 4 massive arapaima's and massive Pacus, which you do not need any licenses to keep. So I ask again how are piranhas worse that those 10ft titans?

.....just a guess but someone may be concerned about perceived potential ecological harm that piranha could cause if somehow released into local waterways.

True, but on the other hand, there was this one time a arapaima, not max size but still relatively large, was found in a local park. Luckily it was found being eaten by a monitor lizard. https://mothership.sg/2023/01/monitor-lizard-arapaina-botanic-gardens/

I live in Singapore too. Are you talking about Harding road where all the restaurants are at? I’ve seen the pond which keeps the arapaimas and pacus. Amazing beasts!

piranhas reproduce fast, they dont take long to reach reproduction age, they can quickly grow population wise to the point where they can seriously affect local fish populations and the people who depend on these populations to make their living.
arapaima will take a long time and a specific set of conditions to get to the 10ft titan you speak of, they dont reproduce as quickly and they take a bit longer to reach reproductive age and size and then the issue is how many will survive to reproduction age before they are eaten or otherwise

^^ this. If you look into Singapore’s water ways, you’ll notice many local fish populations having dwindled because of irresponsible fish owners introducing non native fish species, such as motoro stingray, peacock bass, channa micropeltes. Imagine the destruction if piranhas were allowed in Singapore.

Arapaimas aren’t even allowed in Singapore, unless you get an permit, and most people won’t even own them due to their huge sizes. What is seen at Dempsey hill is an exceptional case.

Ok thanks ya'll for the explanations, I didn't have much knowledge on both fish since you know, their kinda rare in Singapore

Same here in the Philippines, piranhas are illegal, but they can still be smuggled, theres an aquarium cafe that has a few, I also have one but the petshop has to sell it to me discretely. The reason they are illegal is the perceived threat that if they wouldve escaped, they can be invasive, personally speaking, I think its far off they can even be invasive here in asia but who knows. Im pretty sure the main reason their illegal is because people think theyll bite everything when they get invasive, based from the media and movies like piranha 3d ofc.
