My dominant discus died this morning/last night, I had 3 discus in the tank all relatively young and small, one of them grew a lot quicker then the other two becoming already an inch bigger then the other two I thought that maybe it was just because she got a little more of the food an a bit more aggressive but I've woken up this morning to find her dead under some driftwood and just wondered if they was an explanation for this as the rest of my tank seems very happy still.
 
What is your tank setup? Gravel? Filtration? Feeding?

How long have you had them and what do you feed? We need to know all this to help :)

180l Rio Jewell with the filtration system that comes built in.
Usually do a 20/25% water change weekly .
Use sand and it's got a few live plants.
Tank mates are a GN pleco, 11 neon tetras, 3 torpedo barbs and the 3 discus all except one of discus have been in about 3 months and had the tank running about 3 weeks before putting them all in with in the fish all going in the two weeks after that. Put the third discus in about 3 weeks ago.
I feed them discus flakes and frozen blood worms every other day. I hope this helps
 
Water parameters? Ammonia/nitrite/nitrate? Any reason you can think of anything would swing, like pH or temperature changes?
His setup is far from okay for discus... He'll have to read a bit.

In tanks with substrate and low water changes discus are very susceptible to disease and issues until they're big.
 
Was it a wild fish? If so, they are more susceptible to infections/diseases in comparison to captive bred fish. They require specific conditions consistent to their wild habitat.
 
47 gallon tank plus sensitive fish needs more than 20-25% WC a week. What are your parameters before you do your water change? Do you gravel vac with WC? Agree with Hendre Hendre here... Sounds less than ideal.

Almost certainly a water quality issue. Discus need some TLC to say the least, once that's done they're plain sailing
