Is this the fish (attached) you are talking about? It might be
Colossoma bidens, called piripatinga in its native land (Amazon
basin), where other, much smaller fishes are called pacu. This fish
is in aquaculture in various parts of the world. It is eaten in
Brazil, but not preferred so much as _C. macropomum_, which I can
attest is delicious. AFS has a publication on scientific and common
names of fishes from other contries important to the U.S. It's-in-my
office, where I am not right now. The red coloration may be an
artifact of cultivation, or it may have been selected for, but it is
not typical of wild piripatinga.

Goulding describes piripatinga as reaching 20kg, and being the second
largest scaled characid in the Amazon, after tambiqui, which reaches
25 kg.

the fish caught in Texas appears, from its lighter dorsal, darker
venter, rather than the other way around, to be tambiqui.
