Common Causes of Clamped Fins in Cuckoo Catfish

Poor Water Quality

Most Likely

High ammonia or nitrite levels can stress the fish, leading to clamped fins.

Temperature Fluctuations

Possible

Sudden changes in water temperature can cause stress and lead to this behavior.

Inadequate Diet

Possible

Lack of essential nutrients can weaken the fish's immune system, making it more susceptible to stress-related clamping.

Poor Tank Mates

Possible

Aggressive tank mates can stress the Cuckoo Catfish, resulting in clamped fins.

Disease

Less Common

Bacterial or fungal infections can cause systemic stress, leading to clamped fins.
