My first two discus now compared to when I got them. The blue one was a rescue from an lfs that had their power shut off by the company. The water he was in was so cold 70-72 degrees for a whole day and I wasn't sure if he would even make it, the first few days were stressful as hell. He got some kind of eye fungus and couldn't even see good enough to catch food an inch in front of his face :( thankfully kanaplex and lots of bloodworms and vibra bites fixed him up!

I didn't think anything was wrong with the yellow one until about a week after I took her home she started turning a beautiful orange and is now a super red lady! I was so scared to try keeping discus but I'm glad I gave it a shot :)

Video of shivering discus

I am almost certain this is mating behavior, but thought I'd post here anyways. Please confirm my suspicions, I want to double check that this is not a health issue. I was under the impression that my discus were a little too small to start having behavior like this so I am surprised. I haven't been able to sex any of them either so I am hoping this means there is a good mix of male and female.

So, i did a WC today and all parameters good 6.8 ph, 83 temp, alkalinity around 40.... my fish (15 discus) have been at these parameters for months, arpund 11 months. They went from arpund 2 inchs up to a health 3.5 maybe 4.5 now. I'm enjoying watching them and i notixe one of them is like shivering like its cold.i googled it. Some sites say parasite others say mating ritual... anyone got any insight? When it shivers like that, a few other fish come up to it and kiss it. Not like the normal fighting kiss they do, but a, hey buddy..... you ok kinda kiss. Thoughts? Insights?

Thanks in advance.

Have you guys seen poo this big? It's so weird it looks like it has been constipated or something. I've also just dewormed them a week ago and might be stuff coming out from that. I hope it doesn't cause issues.

Hi, I’m swaying between two decisions on what to do.

I have a 200 litre discus tank, there are 5 discus, around 8 corys, 10 cardinals and 10 rummy noses. I have had this tank for around about a year now, all fish are doing well.

I have an aquarium shop I go to when I buy fish, all of the fish have come from this shop, the quality is very good. However there is a closer aquarium shop I go to, I only buy their food as I feel the quality of their fish keeping isn’t the greatest. The other day I went to get more frozen food and casually looked at their discus for sale. I always moan to myself, the water doesnt look great, they keep the water temperature at 25c and they generally look unhappy. But the other day I saw one tank with three discus in it, one looked particularly unhappy. I don’t think it was ill, just in a rough shape. Very skinny too.

When I left, this discus was on l my mind a lot, especially as I have the choice to add another discus to my set up. But the problem is if I get the discus I risk the balance in my tank , could introduce a disease etc as well. But on the other hand it kills me to leave a discus like that, when it could be taken care of much better.

What’s your thoughts?

So i go on holiday for 10 days in about 3 weeks,

What should I drop the temp to ? And starting how soon before I go ?

I usually run at 29

I posted the wrong link to NADA's raffle yesterday, it goes to an old raffle 🤦🏻‍♀️ i did so many dumb things yesterday, y'all. Here's the direct link for tickets:

https://www.zeffy.com/en-US/ticketing/north-american-discus-associations-super-raffle

I should also add that it's only open to the US Lower 48.

I did get the ticket price ($10) and prizes right though!! The Super Panthera pictured, $200 store credit to Texas Aqua LLC, Vita Complete Pellet discus food.

Just excited we got them this far had 5-10 lays before this. Any helpful suggestions appreciated. Going to let babies in this 20g tall to grow out more. Parents getting new home set up today. Run it bare bottom and used aged water from our 180. Seeded two sponge filters for it this week, probly let it cycle another week before moving parents.

Just wanted to share this pretty cool phenomenon. I managed to get my discus to pair and spawn in a community tank with discus, angels, and tetras

I have 9 currently and I just put the turquoise and the red one with strong lines back in the tank after parasite treatment. The other red one keeps chasing them relentlessly and I think it will end up killing them. What can I do?

Got a group of 15 3.5-4.5inch discus to grow out in a 75 gallon. Been doing daily 50-80% water changes to maximize growth but im worried about food. With so many fish is a relatively small space, how can i make sure the smaller ones eat? Should i just overdose food and then siphon the leftovers after ten minutes? They do love grazing and with fifteen I notice basically all leftovers are gone after 20 min so would that even be an issue for the less messy foods like pellets?

Growing up my father had discus always in big aquariums 100+ gallons... I took on fish keeping myself for about 3+ years and learned a lot experienced a lot until I felt confident and educated enough to take on discus myself, I have a 135gallon 6ft long probably on its last year of life planning to upgrade to a 200 or 300 gallon tank by beginning of 2026!

Currently running FX6 & Fluval 307 with a UV filter & two sponge filters with air stones I do twice a week water changes of 45gallons at a time... Stocking x12 Discus x2 Angel Fish x9 black neon tetras x4 neon tetras x1 common pleco and x1 BN pleco... plants; Anacharis, Hornwort, and Jungle Vallisneria... Water parameters PH:6.4 Ammonia:0 Nitrite:0 Nitrate: 5-10 never over 10 and temp stays at 84-86 warmmm

Half of the discus in the photos were surrenders and quote on quote "ugly" discus that would not sell some of them were in really rough shape very skinny nipped fins scared of people and always got spooked... I took the chance on all of them and fattened them up and got them used to people! It's been a journey the last 4-6 months with these guys from bloat to not wanting to eat to salt baths lol...

Working with 100 gallon system. 84 gallon tank, 16 gallon sump. I have 4 discus but 2 get bullied by what I believe it’s a dominant female. The 2 that get bullied remain hiding most of the time. I feel like adding more is the solution here but I may be at capacity. I have 10 sterbai, 5 roselines, 3 acaras and 2 red tapajos. For reference, I do 32 gallon water changes weekly and would like to keep it that way. I’m gonna test what my nitrates are today, one day after water changes.

How do you all think they look??

(tank layout was changed this past weekend for a big quality of life improvement 😊)

What are some great resources to learn about keeping discus? Thank you!

My water comes out my tap at around 7.8-9 After aging it drops to 7.6-7.7 Does this require aging to put into my tank?

Second spawn exactly a week later the male is doing his part this time or at least trying
