Discus care, really so needy?

Discus, due to being propagated extensively in the hobby at this point in various water conditions do not have a super high care level regarding water chemistry (they do not need extremely soft water as used to be thought). They do require clean water with low nitrate levels to remain healthy, and lots of meaty foods for growth in the juvenile stage, which = more waste and the need for lots of water changes.

But I would not buy from a LFS that does not specialize them because they may already not be healthy and you will be disappointed when they die. Discus, once their health is allowed to deteriorate are hard to get to recover, so it's best to buy healthy, parasite free stock.

Back to the fish, can't they be cared for like other fish? No way this store cared obsessively over them, the tanks they were in were covered in BBA and other issues. Basic needs met, no more, I'm sure. But they looked amazing....

I think this was already mentioned, but many stores order them in healthy and allow their health to deteriorate due to improper feeding and dirty water. If they don't sell them quickly you'll generally notice they start looking really bad. So how they look in the fish store, especially if they just got them in, doesn't really represent their hardiness level (which is pretty high given good water quality).

And I'm not sure how much you've researched discus, but the average fishkeeper does often think the discus look great at the store, when in actuality someone experienced with discus would look at them and see sickly, poor quality, and/or discolored fish.

Oh and another thing is the discus they get in may be hormone treated and given color enhancing supplements, so having good color doesn't always = healthy. In many cases if you see juveniles in a LFS with very vibrant colors it can be expected that those colors have been attained by using methods other than just proper care. Because almost any discus will discolor some when put in a new environment, especially if the water is different than what they were previously in.

I've kept discus since '89 and have learned that much of what you've already read in this post is true.

Three main requirements for successfully keeping discus:
1. Keep 'em warm - 82F to 86F
2. Keep 'em clean - For tank-raised adults, I'd do no less than weekly 50%, for growing juvies daily 50%, for adult wilds every other day 50%
3. Keep 'em fed - discus, like most other fish, need a variety of foods to maintain optimum health. These foods can be combined in a mixture or fed separately over the course of the week. Discus are slow eaters, often referred to as grazers. Mostly, they let the food fall to the bottom and peck at it leisurely. Housing them with aggressive eaters is not a good idea for this reason (i.e. loaches, angels and other cichlids). Uneaten food fouls the water quickly so should be removed. You learn quickly how much to give a group of discus at each feeding.

I disagree that discus aren't hardy, as posted earlier in this thread. In their world, they're pretty tough fish. Wild discus sporting scars and missing fins from pirahna hits attest to that.

Also, I don't think things like carbon or purigen are necessary for discus aquaria.

Not magic to keep discus, just a little more work...but they are sooooo worth it.

I've had discus for a year now after 2 failed attempts many years ago. Juveniles are a lot of work to grow out well. Lots of feeding & clean water. I've gradually cut back from WCs every day to every other day. They produce a lot of slime that needs to be cleaned off the glass & decor too.

Adults are less work but I'm still planning on more attention to their needs than my other tanks. They are BIG fish that need big tanks.

Discus can become stunted rather easily, those 3 inch colorful fish sound like they might be. Your best bet as others have said is to get them from a reputable source. Plan on lots of work, you may be able to cut back but better to do that than wish you had.

You're right, they are hardy in their world...I [perhaps mistakenly] was just using the adjective hardy as in "zebra danios are hardy" - hardy as in, fish that can tolerate less than perfect care. And it sounds like discus can't tolerate that for very long. So perhaps instead of saying delicate, we should say demanding. Frail gouramis, Ctenops nobilis, are delicate. Discus are demanding.

Carbon and Purigen, or chemical filtration of any sort for that matter, are certainly not necessary in any aquaria, but they do give more leeway if you cannot commit to changing water more than once a week (which for most people is already enough of a pain). They need to eat a lot of high protein foods, one reason for having to do so many water changes but IMO a good reason for the less than extremely dedicated discus keeper to use chemical filtration.

Discus are specialist fish. They need to be kept alone (not with angelfish or cichlids, for the feeding reasons above) save for dither fish who also like the same water chemistry and temperature.

They require extraordinary (literally, extra from the ordinary) care compared to most fish. Not necessarily more than other demanding fish such as wild bettas, but out of all the fish you can commonly expect to see at the LFS, discus are definitely one of the most difficult.

Just my two cents! I'm no expert by any means, never had discus.
 
The problem with discus is that they don't usually belly up and die overnight. They slowly deteriorate into poor health and getting all the other discus in the tank sick.
 
I have had discus for a little over a year. Adults and juvies. They are by far, in my opinion some of the most difficult fish to keep. Even when you have adults that don't require the 4-6 times a day feedings...they need lots of water changes. I try to go once a week, but usually end up doing twice a week 30-50% water changes. I have to treat them for internal parasites on more than one occassion. Not counting the cost of the fish...I have spent TONS of money trying to keep these fish healthy and happy.
I think they are absolutely without a doubt some of the most beautiful fish out there...but they definitely require more care. They do fine with my staright out of the tap water...no difficulties there. They do not need all the soft water low ph stuff you read about. But most defintiely money and time consuming.
 
Needy is relative to ones perspective. They do like temperatures on the warmer side 82-86+. Warmer water leads to increased bacterial growth in the water. As such, water changes more frequently are required. Any substrate can amplify this increased bacteria, so gravel is a no no unless you are very careful how much you feed. Sand is a bit better, but bare bottom is by far the easiest to maintain.

Not a big fan on AC, but purigen I like, although not neccesary.
 
i use a foam filter system for one of my tanks 38 and Penn Plax Cascade 1000 with all the media including charcoal for a 55 and a 38 have had really good luck. I keep a log of all my water changes use the correct chemicals in moderation and also depends on how many fish are in each tank on how many water changes per week. More fish in a tank more water changes 30-50% max. Have had great success.

Agreed, don't like the temp to high unless they are ill, if ill I usually put them in a sick tank.
