This guy is probably close to 30 inches. His head is wider than my husband's fist. I'm thinking he's going to gulp our aro if we put it in the pond. The around is probably around 20 inches or so. It can stay in the inside tank for a little while longer, but I'd like to get him more space. The giraffe catfish is a good 18" nose to end of tail. He's becoming a prick, chasing our oscars. The husband unit thinks he'll be ok in the pond with the hybrid and the rtc (who is 2 foot plus probably). All I see is a very expensive meal or the death of two fish. Anyone have personal experiences with adding species together like this? The hybrid is a literal pig and pops anything that touches the water. Including hands, arms, water drops, air. He's more of a worry to me than the rtc. Pictures for tax.
