In my 1200 gallon tank i put in 8 Discus some time back. I do not think that they come to their right in there, so i want them out again. But with all the driftwood and amount of volume to hide in, its easyer said then done. Does anyone have any ideas? I am thinking at night, when the lights have bin off for a few houres and the fish are at sleep. Any input on this would be appriciate. A divider is not really an option here.
