White algae is growing on the tank wall and on some plants>0< Very unpleasant!
At the same time, I notice there are many planaria on the glass too, so I did a 50% water change, got a lot out, but still have to do more water change to get the tank back to normal, and of course I will start feeding the fish less.

My question is, my angelfish has been digging those planaria and eat them, I want to know if it's okay for them to eat the planaria?

Yes it is.
The white stuff is not algae but bacteria.

Reducing your feeding is the way to go.
Increasing your water changes would not hurt either.

OHOH! I thought those were algae, and it's not!

Thank you for the info.
After I did the water change, I decided to fast them today!
Since they are continuously digging out those planaria to eat, I don't think they will be hungry anyway...
