I have noticed that my fish is quite smaller than it's supposed to have grown and I don't know what's wrong it which is making it to have stunted growth or delayed growth. I feel it very well and change water for it twice in a week.
What could be the problem?
I think it's the kind specie it was, I hope it's still alive till date or have you eaten it😂. There are some fishes that don't grow so easily. If it's looking healthy and fat, it doesn't mean there's a sickness, it can only be the kind specie it was.
Sometimes fish growth depends on more than feeding. Tank size, water quality, stress, genetics, and the type of food can all play a role. I would check those factors first and find out which one is the problem.
