Well, I don't think it will get much bigger than that. Not a big deal as long as it is healthty.

I was told that discus that are raised alone might die of stress since they like company of other discus.
Anyone can have an opinion, but they should be able to back it up with some solid reasons and experience.

Dead from loneliness or undefined "stress" strikes me as pure speculation.

Did anyone provide concrete reasons or experience to back up this claim?

Stress is a big factor in fish health. A good majority fish tank diseases can be avoided if the stress factors are ruled out. Read any book about fish care it will tell you that.

One good book to read about stress of fish is 'Common Fish Diseases' by Lance Jepson, a vet specialist for fish. It provideds some good facts about fish stress and related diseases.

Hey girl! A single discus would likely hide a lot and be lonely, they are fish who enjoy being in groups of 5 or more. I raised my babies from 1.5 inchers to 4 inches in 2 29 gal tanks, daily water changes of 75% and lots of Beefheart mix.After they got to 4 inches, I moved them to the planted tank I had set up earlier. That way the plants were already growing and I learned to care for them. Cleaning a barebottom tank doesn't take that long, and yes, they grow out much better in a BB tank. The work involved is rewarded by healthy, fast growing fish. You didn't mention how much light is on this tank. If you go with Java fern, anubias, all easy to grow, low light tolerant plants, you can use a minimun amount of gravel to make your weekly or 2x weekly cleaning easier. About fighting, they will establish a pecking order, then they settle in, not like having a constant battle. If a pair forms, there will be some nipping at spawning time, but in my tank, the others move to the other side of the tank for a while. My eggs hatch, but the fry are eaten, so excess fry aren't a concern. I would like to set up a breeder tank sometime though, it's fun to watch the eggs hatch, become wrigglers, then freeswimmers.


The other response I received was from fishlover.

The rules are simple enough. They are different because they apply to different cases.

For display tank, you can do less WCs and house bigger discus with plants. That's because your major concern is not their growth, you feed them less, you are just tyring to enjoy them and that set up is fine.

For smaller discus, you really do need lots of WCs and 5-8 times of feeding a day. In this case, BB tank works much better. Otherwise, you will have some discus stay small and not looking good.

As for how many discus, again, it depends on what is your goal and how deep is your potcket? Is it for a display tank? Then you can buy some bigger discus (at least 4" plus) and have 5 of them in your 77 g tank is perfect. Actually, you can put up to 7 of them and doing 40% weekly WCs will be fine.

Do prepare to pay more money for bigger discus. If you don't have much money and you don't want to do the WCs to grow out the discus, I guess you better off with other types of fish because you will end up losing the fish, which is not going to be cheap anyway. Getting into discus is not cheap. You really have to budget for more than $20 per fhis in order to get some OK quality fish. AND we are talking about juvis with that kind of money. I paid about $35 each for mine and they were about 3" big. These are still young fish and you really should not put them in a display tank and hoping they grow big.

For 4"+ discus to put in your display tank, we are talking at least $50 each, maybe much higher depending on the type and quality. Anything cheaper for that size you really have to watch the quality. You may get lucky if some is having a sale.

They are cheaper discus on Auqabid and e-Bay. IMO, you get what you pay for. I will try to avoid them. Get from one of the sponsors here that is close to you. Go visit the person and pick up your discus is a much better option.

I would not try one discus. Most likely, you will end up losing it because it will never be happy and could lead to stress and so on. Some people may get away with having 2, 3, 4 discus in the tank. Most other people end up with discus fighting all the time and losing them one by one due to stress related problems.


Not the most encouraging since all roads seem to lead to 'Do several discus in a barebottom or none at all'

I would gladly just do one discus with a shoal of corrie and some rams but if everyone is certain that somehow he will become stressed out and die, then I don't want to do it. The only other alternative is to wait even longer and just barebottom tank some juveniles.

Everyone says 'don't buy the cheap walmart fish'. What I don't understand is, if I'm not going to breed them, its just for me to get into the hobby and enjoy a discus, does it matter if it isnt perfect in its appearance, a fine specimen of expensive breeding, as long as I love him or her?

It's like the ones who say to hold off and buy a siamese fighting fish direct from thailand for 20+ dollars (not to include shipping either!) just because you know it will be the very best in color and size and breeding. What good is all of that neon bright color and breeding if I am not going to breed it with another for money? I don't want to spend 35 dollars or more a fish just to know it was raised by a topnotch breeder.

agree 100%... but stress is not some mysterious emotion in fish that comes from unhappiness... it is a physiological response to negative stimulus with measurable levels of stress hormones in simple tests. We know what are the common stressors. Shoaling fish kept alone is not generally a significant stressor... it can be, esp. for shoaling fish kept alone in the presence of larger, and possibly predatory fish... I.e. one tetra in with Discus will be stressed.

Discus, like all cichlids are extremely variable in personality. There are timid Discus that may hide a lot and not be happy alone... hence my strong suggestion of finding an A type personality for the single Discus setup.


Joitjoy... both those responses are clearly speculative in nature... they both say a single Discus will "likely"...

I don't doubt for a second that you could find many folks who have had a single Discus that didn't fare well, and I can find you just as many folks who can share stories like JBs... one Discus kept alone, doing fine.

I myself had such a setup for a good 7 years. The Discus did not die, I put the fish down for personal (and admittedly selfish) reasons.


Discus, like Demasoni and certain other cichlids have a vry unique recipe for success in my experience... the norm is one, or many...
Between 2 and 5 is about the hardest number to attempt... it all comes down to territory and social infrastructure in these fish.

Hope this helps.

If you don't want barebottom, and want a planted tank, you can use sand.

Make sure the sand isnt too fine though. "Pool filter sand" works great. The sand isnt coarse enough so that the mulm (poop) falls through, so it just sits on top and is easy to vacuum off. Its also not fine enough to cause "dead" zones in the substrate.
