Well, now I'm back at TAFE full time, I don't have as much time for my O. I still keep up with all the regular maintainance etc, and spend time sitting with him, but without spending a fortune, is there anything I can do for him, either food, fish, plant, things...???
Any ideas??

Fish don't get bored. If you were to take fish straight from the wild and plonk in a small tank, it may show some signs of stress because it wouldn't be used to its normal environment. However, I would class this as boredom. Fish possess primitive brains, they live to eat and breed, that's about all.

when my Tiger gets bored he chases the pleco, but he hardly gets bored most of the time he keeps dancing and at night he goes to sleep:lol: .
