While I was looking for stuff for my aquarium, we saw a
Sun Conure [centralpets.com] at the pet store this weekend.
A Sun Conure is a parrot, and the one we saw made no noise and was very playful. And it was so beautiful. One of those would definitely make for a great pet (although not for me). I might have considered getting one of them until I did some reading and saw the following on
this page [sunconure.com]:
"Screeching is normal for most parrots. It's how they say hi to each other and how they announce that they're happy. So in the morning and the evening, your sun conure will say "I'm here! I'm here! I'm here!" for ten minutes to half an hour."
Ugh. No thank you. Why would anyone want something that is going to screech at them for a half an hour in the morning? Like mornings aren't rough enough.
I actually think that the main problem with having a bird would be keeping it at a comfortable temperature. We haven't been turning the thermostat up very high, and it would probably be too cold in our house in the winter. Not that I really want a bird in the first place...
Anyway, I did pick up some
panda cory cats [liveaquaria.com] for my aquarium. Below is a picture of one of them.

It's kind of a poor picture, because they are so small, hide when I get near the tank, and almost never stop moving long enough to get a good shot.
I have a 55-gallon tank, so there is plenty of room for a couple of small catfish like those. I'm just a little worried that right now, they are so small that they are easily bullied by some of the larger fish that are already in the tank. Below is a picture of one of them below
a rainbow shark [fishlore.com] (a rainbow shark is actually a catfish, by the way). Unfortunately, the rainbow shark is almost constantly moving too, so he's blurry.

They'll grow quickly, though, so it shouldn't be long until they can hold their own.
