What or who ate the stingray?
I was surprised when it happened. I have unfortunately witnessed a Pseudoplatystoma fasciatum roll up a 10" stingray like a taco and take him whole.
The 14" however had been in the tank with these other fish for 3 years, so it was a surprise.
Not sure, the suspects at the time (1997) were:
a 27" Pseudopimelodus fowleri
a 50"+ Walego leeri
any of 5 Phractocephalus hemioliopterus
the largest weighed 90lbs when he was killed in 2003 by a 24"black shark Morulius chrysophekadion (The smaller shark inflicted repeated bites on his head
either of 2 Sorubimichthys planiceps (48" & 54")
either of 2 Pseudoplatystoma fasciatum (36"-40")
