My uncle had alot of great setups before he passed away, he had everything from a baby shark, pirana's, crabs (which escaped and went a walk about the house).
Unfortuently the shark decided to eat everything in the tank and then it was getting too big for the tank.
Begs the question, what did yas do with the shark Iain?..lol
Gave it back to the shop, having a shark that hungry defeats the purpose of having a "fish" tank lol
