Well, I tried to get a video for Rocky, but my new phone doesn't have enough memory to take video. So for now, some photos will have to do.
An angelfish. There are five of them in the tank. They are about two years old now, and really taking on a nice blue sheen. They're really fun; tons of personality. They seem to enjoy watching the people in the office as much as the people enjoy watching them. They're always getting into these funny, twitchy shoving arguments. They remind me of boys in the middle school locker room. But the tank is big enough that they can get away from each other when they want to, so fights don't get out of hand. I've kept angels in smaller tanks, but I don't think I would again. They're too intelligent to keep alone, in my opinion, but they're aggressive enough that they need a really big enclosure to get along.
Red phantom tetras. I have a school of about 15, I'd guess. I think I have two different strains. My original ones, like the one on the far left, are deep red. The group I acquired last summer, like the one in the foreground, are more of a silvery-pink. All of them are rather shy, schooling under the tree roots. I think the angelfish kind of freak them out, even though I've never seen any attempted predation. Or maybe they just like shade.
My one poor, lonesome little Venezuelan cory. I started out with a school of adolphois, then a school of these. None made it except this little guy. Despite pristinely clean water--no ammonia or nitrites; nitrates consistently under 5 ppm, when it registers at all--they all lost their barbels then gradually disappeared. Lost barbels are usually a symptom of ammonia poisoning. Puzzling. This tank has long had a LOT of gunk on the bottom. The past few months I've been fighting a battle with cyanobacteria/blue-green algae, and that includes frequently cleaning the sand. It's making a difference. I might try more cories next time I order fish.
Diamond tetras. I had great hopes for these, but I'm not a big fan. I think that to look great they need a well-lit, open tank where they can really catch the light. In a shady tank like this they usually just look gray and nondescript. Probably wouldn't get them if I had it to do over again.
Royal whiptail. Possibly the coolest fish in the tank at the moment. Behavior-wise he isn't much. He acts like a typical member of the pleco tribe, which means he most lays around and sucks on things. But he has gotten big and he looks really cool. Interesting eyes, too. Looks like he's up to something. Definitely getting more of these next time I order.
Another shot of the royal whiptail, with a blue angel mugging for the camera. As usual.
