Yellow Belly Pacu

[Drstrangelove]

I looked at fishbase which indicated a max length of 40cm and max weight of 20kg which is I'm sure the source of the confusion. Fishbase is only as good as the people who give it data. If that was for the same fish that would be one truly impossibly fat fish (16 inches-44 lbs.), and certainly not the one on the pics. I tracked down the reference further and this is what I got:

http://nas.er.usgs.gov/queries/FactSheet.aspx?speciesID=428

It says 85 cm length which is a much better fit for 20 kg. (A 85 cm pacu would weigh 16 kg.)

The 40cm length and 20kg weight are for 2 different fish of this species based upon the fishbase links. They were reported years apart and no one at fish base asked for the length/weights (or didn't use the length and weights for both fish.) For comparison, a 40 cm Pacu would weigh a little under 4 lbs.

They also caught one in Florida that was 22" and 8 lbs, which is a nice match for both pacus and the 85cm-20kg reported size.


I think this fish might be a 34" fish, 44 lb fish. Better than a 45", 82 lb pacu I think, but still a lot of fish.

I'm watching this one with bated breath. If these end up staying 18" or less, I WILL have some.

Does anyone know the binomial nomenclature for these?

Piaractus mesopotamicus 5” 35.00 or 3 @ 30.00 ea. rare import of ‘ylw belly pacu’, ‘pacu caranha’- looks like giant pacu but grows to only 18”

The 45 cm and 20 kg must contain typo. A 45 cm Pacu would weigh a little over 5 lbs, so those two numbers can't both be correct.

They also caught one in Florida that was 22" and 8 lbs, which is a nice match for both pacus and the 85cm-20kg size.


I think this fish might be a 34" fish.

Thanks for looking it up.... although I hope you are incorrect..lol

Just spoke with rapps over the phone and he assured me they only grow to 18 inches he also said they are the practical pacu for home aquariums. I trust him enough and have heard enough about him that I believe his words. I'm getting mine tommorow around 4:30 so I will see what the rave is all about. The second it starts to grow and is getting towards 24 inches it's out of here but if it truly does stay 18 inches give or take a couple inches then they will be an amazing option for people who like the looks of pacu without having a 10,000 gallon pond. Im sure it will be fine and that pacu on fish base isn't the same I don't think.

I hope he is correct but I seem to remember he also said barbonymus Altus only get to 8" and I had 5 that were 14". I don't really fault him as there is plenty of misinformation out there.

How big of a tank is he in J?

You and me both. If they only got to 18", I'd want them for sure when I move and get my big tank. I really like the yellow color and the size. Let's both hope that he's spot on!

I guess... but he swears it. 500 gallons

I hope so... as I am close enough to Rapps place to hand deliver a 30 incher for a refund! lol

Good stuff!

I don't click links from the app to a website on my phone, it isn't pretty lol.

These fish are looking more and more tempting. Hopefully I can get my 365 running before they're gone, but I figure that I've still got a couple of weeks of work to do first.

man those fins look great. She is going to be a stunning tank buster

Mine just came in the mail, seems like he wants to bust out of the bag!
