Graduation Day 2

Posted 2010.01.31 19.27 in Aquaria

About a month ago, my little zebra danio graduated from the nursery tank and moved into the big fish tank with all the grownup fish. It had taken him about 4 months to reach 1-inch long, with most of that time spent in various small tanks and containers, before he went into the magic nursery.

Today, my two baby peppered corydora catfish (Corydoras paleatus) had their own graduation day, moving out of the magic nursery and into the big 38-gallon tank where their parents live. It took these two only about 6 or 7 weeks to reach the 1-inch length.

Here’s one of the young corydoras, exploring the new big tank. Before releasing them into the big tank, they spent some time floating in a cup at the top of the tank, to get accustomed to the new temperature. You can see the two of them, along with a baby snail stowaway:

WTF Do Corydoras Eat?

I have these two cute Peppered Corys (Corydoras paleatus) in my 23 gallon aquarium. Originally I got just the one, but I quickly saw how lonely he was getting. He would try and play with the zebra danios, but they would simply ignore him. So I added a second, and they have been best friends ever since. The original is slightly smaller and his name is Doctor Pepper, the second is a bit larger and is named Sergeant Pepper. Anyhow, I’ve been trying to figure out what to feed them, what they actually eat.

Doctor Pepper

According to Wikipedia, “Corys are mostly bottom feeders, so they should be offered sinking pellets as well as supplements of live and frozen foods.” Having read this, I’ve bought special sinking catfish food pellets for them, and I supplement with freeze-dried whole foods (blood worms, brine shrimp.) Yet I’ve never seen them eat these things. The pellets are utterly ignored, until the snails find them. The freeze-dried foods never seem to reach the bottom, everyone else goes nuts for them.

So my two corys spend all their time scrunging around for food, and they don’t seem to be starving, but I can’t tell what exactly they’re eating. Sometimes they scrunge the glass walls, but according to several sources, corydoras don’t eat algae! The only thing I have definately seen them eat, is Sergeant Pepper once ate a tiny squished planorbid snail. The aquarium is infested with some species of planorbidae and consequently they frequently meet with ‘accidents’ that result in them becoming fishfood. I already knew the zebra danios ate them and now I know that the corys eat them too.

But other than this one tiny snail, what the heck are my corys eating?

Sergeant Pepper

It’s a mystery.
