Do Cory catfish need oxygen?

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.
