Rainbow Shark loss balance?
I am not sure what is going on with my rainbow shark. He is in a tank with 3 silver dollar and 3 tiger barbs. I have had them all together since I bought them about 6 - 8 weeks ago. All are happy and healthy, all eating well, water quality fine. I feed twice a day different things each day, like flakes, frozen peas, frozen blood worms, algae wafers, freeze dried black worms. The only thing is that the rainbow seems to have some problem with his balance. He swims OK and goes in and out of his hiding places but sometimes he lays in the front corner of the tank and lists to one side instead of being upright. He is eating OK I think, he is not skinny, and forages around but it is when he is still that he seems to have this problem with balance. I What should I do?
