I don't like fishes, you can't hug a fish like a dog, well at
least not in a non yucky kind of way. 
The only fish I will seriously consider hugging is a
mermaid.
Anybody knows where I can buy a mermaid? 
I prefer pets like cats too.
However, I can't keep cats because of space constraints and
landlord's rules.
In the meantime, it's satisfying to have
something else that's alive in the house besides myself!

My new 40L aquarium is actually like a "Live" TV of sorts... I
find myself just sitting in front of the aquarium, spacing out and
just relaxing. Sometimes I feel like some kinda voyeur,
peeking at the residents going about their business, laughing at
their silly antics and having a sense of satisfaction seeing them
feeding and swimming happily about.
I also play a kinda seeking game where I try to find where all
the residents are. There are so many hidey holes in my
aquascape now, it's really interesting! Sometimes, I wonder,
"Eh... haven't seen that resident for so long! Si liao or
not?"
