I came home to find my juvenile bonsai flowerhorn wedged under a rock, i got him out and he is upside down swimming and his fins are badly nibbled and his color is horrible. I immediately set up my 10 gallon with the same water from his tank with the same sponge filter and bubbler from his tank, I added some salt to the tank and heat. Is there anything else I can do before placing him in it. since its the same water and sponge filter from teh tank, he should experience less stress right? I only added a small amount of salt, I wanted to up the salt to about 1 teaspoon per gallon, but not sure if that is to strong at this point, OMG freakin out here... send some advice my way please
