Hi, I am from India . I have a large 5000 litre pond setup . I have 3 alligator gar , a redtail catfish and a giant gowrami . I had these fishes for more than 6 months. Alligator gar and redtail catfish have been feeding on small fishes without any issues till last week . From last week they are not eating any food . One day they ate food , but thats it . Usually they eat 2 or 3 small fishes . But now they dont . Sometimes they pick the small fishes in their mouth and splits it . Catfish is also behaving abnormally , he eats food and later that day he vomits it .Giant gowami is eating the pellets without any issues . Please help me . Is this due to the weather ? Hope you can help me out
