I have had a Blue Gourami for a while now (about 5 months) that was passed down from a family friend who couldn't take care of it. I had heard that they were easy to care for but, as of right now he is sitting at the bottom of the tank looking a bit pale. He has also refused to touch his food. He normally stays around the top of the tank and also has a good appetite, however, he hasn't been eating as of two days ago. I have checked the water parameters and they all checked out. Does anyone have some suggestions for why he may be acting like this?
