Don’t shave your Corydoras whiskers

23 Apr

I noticed that one of my Juii Corydoras has lost his whiskers, properly called barbels. Other Corys in the same tank seem to be fine.

A Corydoras Catfish can wear down his barbels by digging around for food. Even though the gravel in this tank looks smooth I have read that just pushing and pushing into the gravel can eventually wear down the whiskers.

This picture shows my little Julii Cory on the left with eroded barbels. The one on the right looks normal.

Sand is the referred substrate for Corydoras and I do use it in a few of my tanks. It’s cheap to buy Playsand at a Home Depot, Menards, Lowe’s type-store. So much cheaper than buying Aquarium Gravel.

I’m going to tear down this tank and put sand on the bottom. It seems to me that sand can be abrasive, too, but the idea is that when the Cory pushes on it, the sand moves.

Another pic of healthy barbels. Big gravel in this tank doesn't seem to be a problem but I will keep an eye on my Corys.

Corys also need clean water. Do your water changes. If the barbels are damaged and the fish lives in dirty, bacteria-laden water it could eventually kill it. I am very guilty of being slack about this. After seeing my little Julii Cory with no barbels I am vowing to try harder.

Corydoras julii, the real deal

12 Jan

So many times you see Julii Cory’s for sale but they are not julii, they are trilineatus. I love them both but I did find some REAL julii at our Local Fish Shop.

I bought two at $5.19 each. I hope to get a few more and get a little colony going.

A little credit to the young lady who bagged the fish. She double-bagged them so that there were no corners to get stuck in and also the fish’s spines couldn’t puncture two thicknesses of plastic. I didn’t even ask her to do that!

Julii catfish, Leopard Catfish or Three-stripe Catfish?

28 Dec

In the petstore you will see little Corydoras Catfish for sale that are labeled as either Leopard Catfish or Julii Catfish. Most of time they are actually Corydoras trilineatus, the Three-striped Catfish.

Corydoras means    “helmeted catfish”

trilineatus means    “three striped “or “three-lined”

Here’s how I see it:

Both the C. julii and C. trilineatus can be called Leopard Catfish. The julii has small spots, the trilineatus has reticulations (little squiggly lines).

I almost never see the true C. julii, almost all the Leopard Cats I see are C. trilineatus. Even when you Google julii Corydoras most of the pics are of the trilineatus.

Which Leopard Catfish do you have?

Here's one of my favorites, my little 3-stripe Corydoras Catfish.
