Oscar fish

Making the hard decision to close my tank down and move all my fish on to new homes. Since i got my new job down south iv got no time for the tank, im doint water changes every 10 days, my wife doesnt have the time to do anything other than feed them as she is busy with the kids and the dogs (plus one dog has just had major spinal surgery) with the water quality being shit my oscars are keep getting hith and its not fair, as much as i love them iv gotta do whats best for the fish. So when im home al get a new video of my fish as i have nothing recent. But all fish will be going, the 520L 5ft tank, a fx6 thats not even a year old, arowana red light, waver maker and whatever else is with it
