Flowerhorn turning to black

  • We are currently upgrading MFK. thanks! -neo
Got ya. If the injury is healing that's good. My guess without actually seeing what's going on is something is spooking him. You say he panics when you turn the light on? Is that how he got the injury on his side? Sometimes a bare bottom tank will bother these social and aggressive cichlids. You don't want to take off the light so try doing a small amount of gravel scattered on the floor of the tank.

Get a bigger aquarium as soon as you can.
 
I have bought one water proof blue light when i on the light fish tries to hide and i feed him humpy head but his not eating some time i change my water for now at 2 or 3 days 30% of it and now my heater is at 30℃
 
Actually before i have puted some gravel and big stone but after 3 days he got that black spot so i did case study of fh as much as possible but i find that not to put gravel in aggressive fish tanks so i decided to remove it
 
I have not had good luck bare bottom. They see their reflection and freak out and never get comfortable. Hump head is awful food as well get a small sized sinking pellet.
 
Max i can try of 20 gallon but the length is going to be wide he can swim properly Lenght will be about 44 inches
 
But the width is 7 inch thats was the main problem and hieght is 15 inch i m gone a make bit typical tank
 
Any increase in tank footprint and water volume will be beneficial. Keep your eyes open for used equipment for cheap. I really do think his reflection is spooking him.
 
Just a very light scatter of gravel will help. Just enough so there isn't lots of glass reflecting up at him and not too much to accumulate waste.
 
1 more thing i have heared about deworming when should we must give is it required in my case
