Would this be ultimate fighting? Or would they have gloves on? If we're talking about brawling I'll take a Red Snakehead.....( They have wicked teeth, and lots of PSI per bite)
RTC are killers. But overall, you never know. A RTC could sallow a dovii easy that is if the dovii dont rip his eyes out first. You cant sallow what you cant see.
Nice photo for comparison.
They should plaster the photo of the RTC on the tanks at the LFS for prospective buyers to think about before the take the cute little 2" RTC home to their 20 gallon tanks.
Dovi VS RTC = Lion VS Saltwater Crocodile, the lion may be fearce,but he is going to get eaten if he swims in front of the croc.
