Hello all,

One of my adult rainbow fish is not eating any food except for bloodworms. I tried giving him flake food, freeze dried blood worms, brine shrimp, cucumbers, peas also vegetable flakes for freshwater fish. I have a planted tank and he doesn't munch on any of the plants too. It's getting really difficult to feed him since I have to take him to a separate corner of tank to feed him, if the other fishes manage to see these bloodworms the rainbow fish stays away from the crowd and poor guy would get a very little portion.
I have duckweed in my tank and he doesn't seem to be nibbling on it too.

Thank you for your valuable time.Your help will be appreciated.

Any chance of a picture of the fish and the tank, and a video of them eating?
What does the fish's poop look like?
When it eats the bloodworms, does it eat well?

What is the ammonia, nitrite, nitrate, pH and GH of the tank water?
What is the temperature of the water?
How long has the tank been set up for?

How often do you do water changes and how much do you change?
Do you gravel clean the substrate when you do a water change?
Is the new water free of chlorine/ chloramine before it's added to the tank?

How often and how do you clean the filter?
