Hi, I moved my 2 discus from a 29 gallong tank into a 40 gallon tank about a week ago. I used the 29 original gallons and supplemented the rest with new, conditioned water. I used the same gravel, slate and fake plants to simulate the same environment. I did change from a Penguin BioWheel 170 to Penguin BioWheel 330 however. Since that time, they stay hidden in the corners and rarely come out. They also have much less interest in feeding. One of the Discus seems more affected than the other. The new tank location is getting a bit more sunlight, but nothing major. Any thoughts on what could be wrong? Do they just need more time to adjust?
thanks, Paul
