They may be very good fish just as dogs are good pets but doesnt mean the are smart. They are not reaLLY very smart, and neither are dogs. Thats why they are considered dogs of the aquarium. For an example a cat is smarter than a dog.Dwarf_Dude said:oscars with out a doubt, theyre dubbed "the dogs of the aquarium" or "mans best aquatic friend"

I have seen similar behaviour in crayfish before, one in a shop i sometimes use would pick up a mussel or cockle and then wave it about to attract the fish in its tank, then when they nibbled on the food the crayfish would grab them with the other claw and eat them.bobwumba said:speaking of intelligent, yesterday i fed my crayfish a shrimp pellet and i have a few larger tinfoil barbs in the tank. He spat out the shrimp pellet into little pieces knowing that the barbs would come over and try to eat it and then he attacked them. Crayfish setting traps. has anything like this happened to you?
