This pair of discuss has 3 attempts with all eggs eaten up, 1 times with few fry coming out but still eaten up at the end.
this video is their 5th attempt.
some things that I think it may help:
- young pairs are less experienced, sometimes looks like they are not in harmony after laying eggs or frightened, then they eat up all eggs, if your pair only has 1 or 2 attempts, you can looking forward to their next attempt.
- water change. I keep a 80% water change everyday when they are in a small 2 feet tank. (water is coming from the top-roof water reserve, which is kept for sometime, and singapore tap water is quite soft). but after they lay eggs, i keep 20% water change everyday.
- I put 7 disuss with a clearer fish in the small 2 feet tank, with only on-top filters, not decorations at all(during the time I just moved to my new flat) tank is small but really clean. after the 2 lay eggs, I only remove the sucker fish out and the rest discuss is still in, so the competition is still on in the tank. the pair is still the king. but I remove the rest after the fry came out. just to release the stress level of the pair.
- food: I feed them frozen blood worms, washed before feeding and some dry flaker food. they have enough food and looks healthy and strong.
- no extra lighting, I put the tank near my rear balcony, there is no direct sun light on the tank, so the fish enjoy the nature day-night cycle.
- a heater to keep the temp 28′C at night
- some luck 
My 40+ young discus only has 3 survive now.(1 big male, 2 females) and I am waiting for their 1 attempt…

Hey, I recommend …
Hey, I recommend joining a fish forum. They have people that tell you how to breed fish and things like that and you can ask questions. There are a lot, but I recommend AquariaCentral. (Google it) Another one is FishForums(.)net. I think AquariaCentral is better though.
Hi ! i wanna buy …
Hi ! i wanna buy discus fish ! and im wondering if they are hard to take care of ? high maintenance ? and i wanna get a pair wat would be a proper breeding condition? thank you =]
There’s no egg …
There’s no egg eating in the video. I assume you mean the young are eating the adult fish… Discus are one of the very few breeds of fish that do this. The young feed off the mucus (fish slime) that coats the fish. Uaru are known to do it too.
