i responded to an ad for free fish went and picked them up and the wife hates them and theyre bigger than i thought 4 large red belly pacus and a giant redtail catfish looking to trade or sell text 8123255695 for pics and details.
There's a reason the guy you got them from gave them away. Rtc and pacu are probably the most abused fish in the industry. They don't belong in aquariums because of the sizes they obtain.
That being said even giving giants like these away for free is a challenge in its own.
