Food. Feeding time is the highlight of my day. And when my owner shines that laser thingy into my tank for me to play with.
People who like fish.
Don't get many radio stations in my tank...
JAWS! Sometimes when my owners aren't looking I put my dorsal fin up above the water and swim around going "Duh nuh....duh nuh....duh nuh nuh nuh nuh nuh NUUUHH..."
I can now see the television from my tank's new vantage point, only to discover that my owners never watch it. Oh well.
Books and water aren't really a good mix...
My owner, who rescued me from the pet shop, feeds me faithfully twice a day, and defends me from that large black cat who just loves to try to stick his paws into my tank....yikes.
