Viewer discretion advised, as always, when it comes to vultures...
The story of forced upgrade from 4500 gal to 25,000 gal is narrated at the beginning of the video. Most likely the growing TSN pair (over 2 feet now) has been bad at nights. Killed one female vulture, 24", couple weeks ago. I increased the TSN and Co feeding 2x-3x. The vultures still sustained bites to their fins and body, albeit less frequent. I reached a breaking point and rehomed them into the 25K. Vultures have not sharp spines in the fins, hence rubber lined 25K should be safe.
The 6 years old, 24 inch female TSNs killed. As you can see the remaining 4-pack of vultures hasn't disdained their just-passed schoolmate and partook of her tummy and tail too.
Here is vulture dentition, that allows them to rip off chunks and strips, as opposed to most catfish who must swallow their feed / prey whole. It is not at all like the sharp teeth of goonch, African tigerfish, golden dorado, bowfin, snakehead, or marine sharks. They are the same sandpaper tooth patches but the patches form a narrow, sharp ridge on the top and bottom, which immensely increases the pressure at the same jaw muscle strength, and hence the holding power.
It's like wire cutters versus pliers.
Then vultures use their body to death roll and jerk, etc. to tear pieces off. Even with such equipment, as I had reported before, they rarely are able or motivated to start dismantling their just-passed tank mates from hard, taut, elastic muscle parts covered with tough skin. They prefer to start somewhere on the body where they can get a good grip, like the ventral, soft side of gills, the anus, and the softer ventral cavity / tummy... fins too but they are not as attractive to them as the guts and flesh...
