Hi everyone, I have a very healthy rainbow shark in one of my tanks, where he is the only shark. He is very active and displays normal behaviour. There are plenty of places for him to hide amongst driftwood, rocks and caves as well as lots of plants.
My water parameters are all good and I do a 50% water change each Sunday.
Whenever I put food in the tank, my shark immediately goes from a really dark colour on his body (with bright red fins) to a very, very light grey (fins remain bright red) - the change is quite dramatic! Within about 5 minutes of feeding, he is back to his original dark colour. Its a BIG change in colour and he looks like a different fish!
He is otherwise happy and healthy.
Any ideas?
