Discus Tending It's Eggs
One of my Discus apparently laid eggs and is now tending them. I can see it fanning them and then (at 25 seconds in the video) it goes vertical. Is it trying to lay more eggs or is this the male and he's trying to fertilize them? Any insight is appreciated, I would love to have little discus babies! I noticed a clutch of eggs a couple days ago but they are now gone. I'm thinking one of my huge catfish got to them. Hopefully this clutch will last a bit longer.

How am I supposed to do water change? The eggs would be out of the water during it.

Here's the video: YouTube - Discus Tending It's Eggs

You could try not changing as much water but maybe more frequently, but I believe you will need to move the pair of discus to a breeder tank with what are called breeder cones. They lay the eggs on the sides of these rather than the glass. Try googling breeder cones for aquariums.
Either that or remove the catfish and any other fish that may eat the eggs from the glass.
Large sponge filter would also be needed in the breeder tank to prevent babies from being sucked up the intake on your filter or a sponge prefilter placed over the inlet on the tank they are in now. Sorry ,that's all I can offer. Though I had the opportunity to care for discus, I did not have water suitable for them to attempt breeding. Good Job.

I would put the pair in there own tank with a clean brick seeting upright and they will lay on that most times. you will need a sponge filter for filtraition but not to much air going to it discus are weak spawners so the less water movement the better while they are laying after that it can be turned up. you must be very careful if the fish spwan and there eggs hatch because discus fry feed of the parents slime coat for the first few days and if not watched very closely they can kill the parents over night if it is a big school of fry. you will need to start raising baby brine shrimp if you make to this point it is a must.

IDK how to do anything...but dude! That's so must be really taking good care of your discus to have them breed! I'm not too familiar with them, but I know they're delicate fish!
