Pacu caught in a Jersey lake...

  • We are currently upgrading MFK. thanks! -neo
Understand your point and agree. Sweeds lake gets a pretty thick layer of ice on it, not just cool water so I doubt it will adopt to that. I know that lake I've fished it.
 
This label is not wrong. Red belly pacu do grow to 10". It just fails to mention that they then grow to 24", 36". That poor pacu didn't even make to 10" before he was dumped.

The baby oscars are huge compared to the baby pacu in this tank. I'm certain that my fish came out of this tank.

It is easy enough to be Monday morning quarterbacks and say that whoever owned it should have researched it first. Why? If the fish grows to 10", a 55 gallon tank would be adequate. I just did a quick search on keeping pacus. Here's an expert's advice--they recommend a 250 gallon tank.

Here's another stating "at least 250 gallons"

2 gallons per inch of fish

Here's another "expert" pacu usually get around 12" in an aquarium. Need at least 200 gallons for adults.

Here's an expert that has a pacu in a 180 gallon tank

The above were the first five sites I clicked on in my research on pacu. From my internet research today, a 200 - 250 gallon tank will work for pacu. Ten years ago when we picked up our fish at a moving away yard sale, I joined a pacu forum to learn more about pacu. The members were really gung ho about their pacu, I suspect that the owner of the forum lost his fish first. Two moderators with pacu in 75 gallon tanks both had their pacu die suddenly at two years old. That was the end of the forum. There was never any discussion on pristine water parameters. I went into our WalMart and spoke with the manager in charge of the fish department. I showed him this picture.

They stopped selling pacu at our WalMart. Now if I see pacu being sold in other stores, I show them pictures of my pacu. I wish this special fish was available only by special order. It is hard to believe that a fish that costs $6.50 will cost $$$$$$$$ to house it for its entire life. The information on pacu is WRONG. There is no way to research pacu and know potential size, life span, housing requirements, because the experts are wrong about this fish. Most pacu are doomed to short lives in horrific conditions. sad.
 
This thing's make me mad. Whay LFS don't tell the truth. 10'' this is JOKE. Tnx pacu mom for showing this label.
People trust store not google. This is answer :)

As Pacu Mom is pointing out, a lot of times, the lfs doesn't know any better either, and are just going by what's on the internet
 
Obviously someone dumped it, wouldn't last through the fall anyway.

Hello; Not that I know one way or the other, but we have been suprised by the ability of some species to survive in new habitats. I saw fire ants in TN just south of Knoxville about six years ago to name just one.
 
I liked the picture of the hand next to the pacu. My first thought was that the pacu were still small. I tried to take pictures with my hand against the glass. I failed. Here's a picture showing more living room reflections than pacu. (too much light in the room right now) If you look closely, you can see a lot of my Leonardo. Besides too much light in the room, Leonardo was extremely uncooperative. I got the measuring tape out...both fish are at least 12" tall. They are fat big boys.

There was an article about some kid caught a 14" pacu last spring in Minnesota. I was surprised that it survived the cold waters especially after ice thaws. There are pacus thriving in northern regions, especially in some lakes/rivers that won't get cold (Lake Columbia in Wisconsin is the example).

You're right, they won't survive the winters, but if there are any hot springs or power plants discharges they will not only survive but actually thriving.
