Moving an Oscar from one tank to another is a doddle. You often hear people talking about using large towels that they put in the tank to catch the Oscar. Forget that, that is far from the best way of doing it. All you need is a large net, a large bucket, and a small hand towel that is big enough to wrap the fish in. Doing this with confidence will make the job a lot easier. Catch the fish in the net, straight into the bucket that has a little bit of water in it, it might be easier if you actually have the hand towel in the bucket already, wrap the whole fish up. And then all you do is lift the fish still wrapped in a towel and put it in your tank and just let the fish swim out of the towel. Okay, you might get a few drops of water when you take it out of the back it but it's certainly a lot easier than trying to catch the fish using a towel and not the net
