Do cory catfish die easily?
Durable and hardy, Cory Catfish lifespan can be long compared to other fish. That said, it’s not uncommon for some Cory Cats to die shortly after being added to a tank. This could be due to the stress of being transported or shifts in water parameters between home tank water and store display water.
Why are my Corydora catfish dying?
Your cory catfish may be exhibiting these symptoms due to an improper acclimatization process, water temperature or pH changes, poor sanitation, water poisoning, or self-poisoning due to stress.

Partial water changes should help keep nitrate low. Ammonia and nitrite are extremely dangerous to fish and even in small amounts can prove fatal to Cory catfish.
Why are my catfish dying?

What pH do cory catfish need?
Water Requirements for Corydoras A pH between 7.0 and 8.0, alkalinity between 3° and 10° dKH (54ppm to 180ppm) and temperature between 74° and 80° F are ideal conditions for most captive bred Cory cats and their relatives.
Is 3 Cory catfish enough?
Tank Size: Cory Catfish are pretty small fish. Technically, a single Cory should be fine in a ten gallon tank. The problem is that Corydoras are not happy when kept by themselves. Since they are schooling fish, Cory catfish should be kept in groups of 5 or more.
How many Cory cats should be kept together?
As a relatively small fish, they crave safety in numbers, so a group of six corydoras or more (all of the same species) is highly suggested. These peaceful bottom dwellers can be kept with pretty much any community fish that won’t eat or attack them.
Do Cory catfish need oxygen?
The water in these is warm and shallow, and holds less oxygen. Most fish wouldn’t be able to withstand this, but Corydoras can gulp air from the surface and use their posterior intestine to extract oxygen from it and pass it into their blood where it’s needed.
How can I tell if my catfish is dying?
Loss of appetite. Weakness or listlessness. Loss of balance or buoyancy control, floating upside down, or ‘sitting’ on the tank floor (most fish are normally only slightly negatively-buoyant and it takes little effort to maintain position in the water column) Erratic/spiral swimming or shimmying.
Do fish feel sad when another fish dies?
Researchers say this behavior is probably due to stress hormones released into the water by the dying fish. Few studies have looked into whether fish actually mourn their dead, but this seems conceivable – at least for fish that live in pairs, like the French angelfish.
Can a stressed fish recover?
Once the panic has passed, the fish must also regain its natural balance. This can take hours or days, even after only a short period of stress. Long-term changes, such as a poor or unsuitable environment, are handled with the same initial response – an alarm message to escape.
How do I know if my fish tank has too much oxygen?
The signs of too much oxygen in a fish tank are bubbles escaping the surface and increased dissolved oxygen levels. Fish will also show abnormal swimming behavior, open mouth breathing, excessive appetite, or lethargy. If left unchecked for too long, it can be fatal to the fishes’ health.
How can you tell if a fish is in shock?
Some fish succumb to pH shock immediately. Others may exhibit symptoms including thrashing, darting, gasping, swimming near the water’s surface and trying to jump out of the tank. Such symptoms are the same as those that indicate toxins in the water — either cause is serious.
Do Cory fish eat other fish?
Cory catfish suck up food with their mouths and will not bite other fish intentionally or by accident. They are social in nature and are happiest when kept with at least three members of the same species.
