So you have finaly relized your NOT the best pacu keeper!!!!!
Its pretty funny to see this thread (you selling the pacu) because i remember your threads a few months ago when you got the fish. You just wouldnt listen to anybody when they were telling you to give it back to the store while it was still small. You just kept ignoring their posts and saying that you care for your fish very much and want them to be healthy, although you were keeping the pacu in a 40 gallon hex, and your idea of upgrading for the fish was a 75.
If i had a 15 inch pacu that i had to get rid of, because i didnt do my homework before i got the fish, i would give it away for free or donate it to a public aquarium.
