I've had my Bronze Cory for about 3 months now and he is definately the life of the party when it comes to my little tank. He's grown quite a bit, about 8 cm or so now, which is larger than the typical...and quite the little pig. I swear when he sees the food sinking he'll rush over and wag his tail, it's crazy.

We got our first tank and set it up according to your website's recommendations - heavily planted with pebble bottom and a few rocks. We got one pair of mickey mouse platys and two bronze Corys and one Betta. The Betta does beautifully with the other fish and they co-exist peacefully. Much to our surprise, we now have had baby Platys followed by baby Corys. They are all thriving and we have done nothing special at all, other than we have plenty of current and the temperature of the tank fluctuates within their accepted range: cooler to warmer, as a result of water changes. We feed them flake food and spirulina, and Betta food for the Betta. There are plenty of areas for the young to hide in the leaves and rocks, and the adults don't bother them as the feeding schedule is pretty predictable. Our experience with the Bronze Corys is that they are easy hardy fish (we are novice) with lots of personality.

I have three Bronze Corys. They live with 2 Pepper Corys, 1 Panda Cory, a female betta, some guppies, 3 platies, and a few others. I love how the corys just move around the tank as though no one else is there. They just go on their way, scavenging for bits of food, and just move over whoever gets in their way. When one of them goes to the top, it gets the other 5 going, and then it looks like they're playing. They have such a great temperment, and I would recommend them for any hobbyist.

I have bred cory cats in a pH of 8.4 and well over 300 ppm carbonate hardness, and raised scores of babies to adults. Green cory cats are easy to breed, and tolerate all kinds of water conditions.

I purchased 3 bronze cory's for my 75 liter. They are the most interesting bottom feeder I have ever seen! They constantly cruise around together in their little group all day searching for anything to eat, and every so often race to the surface and back for some air. All the while basically never leaving each others' sides. Amazing fish to watch. I would suggest buying no less than 3. Guarantee you will be pleased with this playful fish.

How can you not love these critters? I made the same mistake as mentioned above - buying just one. It was restless until I got him a mate. I now have three and they're doing mighty fine. They just stuck eggs all over my tank for the second time 2 days ago. Hope I'll manage to raise and keep a few. When I think of these guys, the term bottom feeder instantly loses all of it's negative connotations to me!

I have a small tank (holding just 11 litres) containing 4 neon tetras and 2 bronze corydoras. This tank has been up and running for just over a year and my only loss has been a single neon (originally there were 5). The 2 bronze corys in this tank live in perfect harmony with the tetras, they are always on the move (scavenging in the gravel and darting around the tank) but this doesn't seem to bother the neons in the slightest. The two corys stick together most of the time, when they do finally take a rest they sit on the bottom like two parked up motorbikes and whenever you walk past their eyes swivel as they watch you go by. They don't seem to like being stared at for too long, when they meet my eyes they tend to (jump) move to the back of the tank. These two fish are definitely more interesting than I anticipated them to be, especially when I heard that they would just cruise along the bottom and ignore everything going on around them. They are now about 7 cm long (twice as big as when I first got them) and seem to have stopped growing. Certainly a good fish to have.

I too have fallen under the spell of Cory’s. So much so, I have studied them intensely and turned a number of them into a developmental biology project. They are, after all, a robust and quite easily a renewable resource. To assure all the Cory lovers out there, I am one too. Everything I did with them was researched and their survival was priority. Otherwise my studies would not have taken place. I have studied and documented a thirty six hour old healthy embryo, still nestled inside its soft shelled egg. You can see the embryo’s two-chambered beating heart. The slightly transparent eggshell is called a chorion. The chorion surface is covered with super sticky dots, enabling the female to lay eggs on glass walls and undersides of leaves. The “whiskers” on the catfish are called barbels. Their barbels happen to be covered with taste buds. Taste buds can also be found on their bellies and fins, but not as many. Many of you have seen how a proper sized shoal can “dog pile” on each other. Do they taste each other? Do they identify each other by thinking “Hhmmm, this one must be Fred!”
