The Corydoras Catfish, or Cory Cat, is an excellent addition to most community tanks because of their peaceful nature. Bottom dwellers, they are content to constantly rummage around the bottom of the tank looking for scraps. This is a very cute and endearing catfish with many different species.
They prefer to be in schools of 6 or more but many keep one or two corydoras in their smaller tanks.
Cory cats enjoy feeding on tropical fish food that will sink to the bottom such as algae wafers or shrimp pellets.

Corys are the most peaceful fish I've ever owned. They seem to get along with every other fish, and mine even allow themselves to be transferred to their travel tanks by HAND for cleaning purposes!
Can I have corydoras if i have a pleco?
|They should be fine with a pleco. We have cory cats in many of our tanks with plecos and have not witnessed any problems or issues and have not heard of any.|
I want to keep several because I've always liked them since I was little. I was wondering though, if it is best to keep 4 or more corys of the same color or if it didn't matter if I kept multiple varieties (bronze, skunk, leopard, albino, peppered or green) together?
|Generally speaking, you should be fine mixing the various cory species. You may not get to see the schooling behavior that these little guys can exhibit if you mix the different types. Research the various types before you buy them because certain breeds are hardier than others.|
I too have a cory, and must I say they should be part of any community tank. My little guys stayed small for two years now. And I don't know what's wrong. I know my cories a boy, (they tend to be smaller) but is it something I'm feeding him? Oh! And also I found out cories can get along well with almost any bottom dweller! (Not plecos) Mine hangs out with a plated catfish, and they have been buds every since I put them in. But it's a great fish, get's along with everyone!
I started out with two cories, which a few months later I found out were of opposite sex because I found about a hundred eggs adhering to the glass of the tank. My two algae eaters took out all of the eggs, or so I thought until I found an almost microscopic thing that I at first thought was a piece of flake food scurrying about the gravel. It was a surviving baby. He is now three months old and all three cats are doing well.
Our bronze cory "Mr. Catfish" moved from South GA to NH in a jar, and back to GA. He was a wonderful pet. He died at age 15. I thought that was a short life for a fish! Little did I know! We still miss him.

I have several corys, 3 pandas, 2 bronze and 3 spotted. I too have witnessed a bronze cory laying eggs everywhere, and the other fish, pleco included, come along and eat them. But about a week ago I found a baby panda. This is unusual in that I've had my 3 pandas for over a year with no offspring. This new baby is almost half the size of the grown ones, so it's been hidden very well since birth. So my advice, never give up on offspring, they come along when you least expect it.
We got a cory and he is just awesome! I keep reading everywhere that they're peaceful and shy but mine is a little out there. He hangs out with all the other fish and when he sees our barbs chasing each other he JOINS them! He'll chase them around the tank and it really is the cutest thing ever. We call him puppy because he acts more like a pup. They're very entertaining and highly recommend them for any tank.
I have 9 corydoras in my community tank. 2 Peppered, 1 panda and 6 bronzes. They are the funniest things and very lively. Most of them are juveniles but I have at least 1 adult female and she is bothering the boys for attention, she is so full of eggs if she doesn't mate she will burst. They bother no-one and no-one bothers them. They flock together in groups according to species but will intermingle a bit. The panda is alone because several pandas I have bought have died. These guys stress out very easily and are subject to illness after being freaked out by moves etc. Wouldn't be without my cory cats now.
I have a little cory in my community tank as well and he isn't shy in the least. Every morning when I drop his wafer in there's a little three way tug awar over it between him, one of my tetras and the female betta in the tank and the cory holds his own. Literally the three of them will take turns scooping up the little wafer, dragging it as far as they can and then when they get tired some one else snags it until the tetra and betta get tired and let the Cory have his breakfast which he gobbles down happily. Everyone told me he would hide in the plants and tower and I would rarely see the little guy but he's always out there when I look in the tank and some times even comes off the bottom to see what the others are up to.
|Yep, these are great little fish packed with tons of personality.|

I have only just stumbled across the pleasures of the Corys, but I have a tip if you want to breed them. When you see them doing their little dance, especially just after they've gone into the 'T' position, the female will start laying eggs. Once she's finished, very gently, roll your finger over the eggs. The eggs will then roll over till the sticky side comes into contact with your finger. Gently move the egg to the plastic holding tank remebering not to take the eggs out of water. Reverse the proceedure placing the egg against the side of the plastic holding tank. If fertilized, they'll turn from white to brown to black, then hatch, depending upon the temperature in 3-7 days. I'm feeding mine frozen brine and they're doing great. Hope this helps and good luck.

They are very peaceful in nature. However I have noticed for he last couple of months that when feedings Plecos and Corydoras the same food (Algae wafers or Shrimp Pellets), the Pleco's can be very territorial about the food. If a Cory tries to eat, it can get pounced on for the food. Ideal time to feed both is when the lights are off. Also I've been experimenting and to stop this problem I feed them seperate food (Algae wafers for the Pleco and Shrimp pellets for the Corydoras).
