[i]Pseudoplatystoma fasciatum[/i]
In the 'Tunnel of Underwater Life'. Has a tank to itself and often seems to get fed whole squid - fun to watch it by sucking the whole thing in.
The Palms Tropical Oasis will close permanently on 5th September 2010. Not a major zoo but always reliably interesting and somewhere I've been going for years. I made my final visit after spending the morning at Hillside. So long, old chum.
