Red belly. The majority of red bellies lose their red coloration as they mature. I had assumed we had black pacus when we got ours, because they were black.....I was wrong. Take a look at this picture of Pacu Lady's black pacu. He was 28 years old and 40 pounds when he died in a tragic tank failure. He definitely looked different from the majority of pacus posted on MFK.

Black pacus are not common. Most pet stores still selling pacus are selling red bellies. Half the posts on MFK where people are selling "black" pacus, are actually selling red bellies. They are funny threads, because some one will always correct the seller and set them straight. Haven't seen one of those ads in a few years, so hopefully people aren't buying these wonderful fish only to have to unload them down the road.
But you are correct Al, in your concern about tank size. My understanding is that red bellies can get to 36". I'm having trouble with our background, so our big tank is still not set up. Our 24" high 300 gallon tank is way too small for our pacu. They don't have much water to swim in. If we remove 1/3 of the water during a water change, the pacu have to swim on their sides to keep in the water (which they prefer doing
) They have to modify how they pick up food off the floor of the tank, or their tails are out of the water and hitting the tank lids. The OP has 7" more than we have right now, so he may be OK for the long haul...time will tell.
