Make sure to dechlorinate the new water, and to pour it in slowly as disturbing the substrate can lead to ammonia spikes. You should also test the water quality often — this can be done in aquatics stores or by using home test kits.
Corys are very sensitive to water parameters so monitoring the water quality will keep them happy. They are also susceptible to a few diseases such as red blotch or ich. They eat by sucking up food with their mouth from the ground, sometimes digging so that half their face is buried. Corys will eat most of the basic foods, such as flake food, but sinking pellets that sink to their level replicate their natural feeding habits better. These fish will also enjoy bottom feeder tablets, shrimp pellets, and algae wafers.
Bloodworms and daphnia make great treats too. They have also been known to eat the small eggs of other species in the aquarium, so be wary of this if you hope to breed any of their tankmates. Corys will spend most of their active hours searching for food along the substrate, picking up sand with their mouths and filtering through it. If you can provide soft substrate, places to hide, and great water conditions in a community tank full of peaceful species, then you have the beginnings of a great cory catfish tank.
They have a great personality and are easy to care for making them an ideal fish for beginners and experts alike. With so many to choose from, you are bound to find one that appeals to you. If you are new to fishkeeping, make sure you follow our advice on setting up your fish tank before introducing any of these fish.
We have two trilineatus 1. The male trilineatus is quite the stud and has fathered babies with both the spotted cory and with his own three-lined partner. About once a week, the male trilineatus is hounding someone and we get a clutch laid by one female or the other. We have had only one baby avoid predation long enough to get big enough to be seen and evacuated. Many eggs end up on the glass.
We were able to save some of the eggs and raise 7 of the trilineatus x ambiacus in a separate container, and then saved some of the eggs from another pairing of the trilineatus and have about 11 trilineatus babies. They are smaller than the male trilineatus and I suspect they are beta males, and the plan is to separate the spotted and three-lined to take the pressure off.
They are about 5. However, they mate regularly and the whole process has me glued to the tank. Both males try to push each other out of the way but she loves them both.
Can somebody tell me what is going on when the male lies on his side and the female appears to be taking sperm from his side. Or underneath? I have only two healthy young but she always lays her eggs on the side of the tank and they get eaten by any living thing.
Bronze Corys are available in several color morphs, including green, bronze, albino, and black. They do well in a range of conditions but should be kept in schools. Although this species may be seen for sale in pet shops, it rarely is the real McCoy. Instead what is labeled as a Julii is its kissing cousin the Three Stripe Cory.
True Julis have spots that are generally not connected into long chains, as they are in the Three Stripe Cory. Panda Corys are highly social and should always be kept in schools of its own kind. They get along with virtually all other peaceful species and have been known to school along with other bottom-dwelling species.
Pandas prefer cooler temps and are suitable for unheated aquariums. Pepper Corys are perhaps the most commonly kept member of this family and are widely available at pet shops everywhere. They are peaceful and get along with virtually all fish, but should not be kept with large aggressive species. Skunk Corys are more sensitive to elevated ammonia and nitrates than other species. For this reason, they are not recommended for a brand new aquarium. Instead, wait until the tank is matured before adding this species.
You can keep them in one aquarium by treating them the same type if they have a small difference in traits. You should treat them for internal parasites for better results. You have to check the different sizes of the tank and note the number of Cory Catfish you will keep in it. You can choose any size between ten to twenty gallons depending on the number of fish in it.
Budget is also one of the essential things that you should consider while deciding the size and type of container for the fish. You should not change the size of the tank after placing them. If you fulfill all their requirements in the tank, they will not feel any problem. You should get a bigger sized tank for them; ideally, 10 or 20 gallon is a good choice. Fish sleep around 8 hours a day, so you have to make all the arrangements.
It will depend on the expertise of the owner that is keeping them. If the owner is a beginner, you can keep the 8 to 12 fish in 10 gallons. Slowly increase their number when you think you can note their movement and environment are suitable.
Increase the capacity of your tank when the number rises from twenty. You should not increase the number from this limit because you cannot control their movements. There is the same method to start the aquarium in this tank also.
You have to start with the 20 fish in the 20 gallons tank. But in general, Corys of the same type seem to stick together most often. If aquarium size permits, Cory Catfish school in groups of six or more. Cory Catfish schooling behavior is a pretty interesting thing to see as the fish move throughout the tank synced like a precision dance ensemble. Cory Catfish Size: Depending on the specific type, Cory Catfish size can range from about 1 inch to about 2. Their diameter can range from about the size of a dime to about the size of a nickel.
They are thicker near their heads and taper off near the tail, creating triangle shaped look. Cory Catfish also seem to really enjoy a tank with lots of live plants. Live aquarium plants provide cover and hiding places for the fish to rest. Finally, be sure to include rocks and decorations that provide places to explore. Water Parameters: While Corydoras Catfish can do well in a wide range of water conditions , keeping the fish in established community tank water is a safe bet:.
Aquarium pH: 7. While aquarium pH and water temperature can extend beyond the traditional community tank range, its important to maintain stability. So avoid sudden shifts in conditions. Make sure Ammonia and Nitrite levels are kept at 0 ppm, and control Nitrate buildup with regular partial water changes. Poor Water Conditions: Cory Cats do not do well in tanks with poor water conditions.
High Nitrates seem to stress Cory Cats and make them susceptible to diseases. Also avoid excessively stirring up the tank bottom while cleaning. This can release a large amount of decaying organic matter into the water column and start a bacterial bloom. The same goes for rearranging decorations. Corydoras Catfish may develop white patches around their mouths and barbels. This condition needs to be treated right away.
