discus in 40g EI tank

From what I have read a 40 is to small for any discus. Double that volume and you can have some. I think you should read some forums about discus or maybe a discus keeper will chime in and give a more insightful response.

From my understanding discus require a lot of water changes with water low in TDS and higher temps. Extra work..... lot of it i think.

Maybe you could consider pearl gouramis or something different for a bigger species?

 

cazandchris I am a newbie to discus and planted tanks, but I have kept cichlids and some other tropical fish for several years now. I have a 46 gallon bowfront tank, and I have had my FOUR discus since March of this year...not to long, I know, but so far, so good. They didnt go into my display tank until May. I just starting doing EI, and the 50% weekly water changes, about 3 weeks ago. I was actually thinking I may do like 30% twice a week, like I used to....they do create a good bio load. What Ive read is 1 adult discus per 10gallons(40L) and they like highly oxygenated water

I have my tank set at 84F (28-29C)....when they are younger, the higher temps are more important, and you will have to feed more often, due to higher motabolism, and do more water changes cause of this, but once they get older, you can back off the temp, and the amount of feeds per day. When I first got them, I kept them in a 20gal. bare bottom and fed them up, and actually had the temp in that tank at about 87F (30+C)

Maybe if you have room, try to get your feel for them in a bare bottom tank first, before putting them in your planted tank. Then when they get bigger, you can upgrade to a bigger tank....thats my plan

I am a member of Discus Forums :: Index

Take a read there, and see what info you can gather....discus are beautiful fish, and they have a great personality

Hopefully someone else will chime in and give their opinions, and correct me if Im wrong with any of my advice....again, Im a newbie to these fish, so take any advice you can from me with a grain of salt...hahahaha

Good luck
Eric

 

Thanks Tom,

Does that mean if Im following Greg Watson's suggested EI dosing regime for a 40-60 gallon tank, using:

40-60 Gallon Aquariums
+/- 1/2 tsp KN03 3x a week
+/- 1/8 tsp KH2P04 3x a week
+/- 3/4 tsp GH booster once a week(water change only)
+/- 1/8 (10ml) Trace Elements 3x a week
50% weekly water change

I should cut all those measurements down by 60%?

Ive been trying to grow my plants, and havent bee that successful so far, and I think this may help

Thanks for the input about the 2x/week water change schedule...I will do that from now on....or as close to it as I can

Well discus are considered "schooling fish" so in that aspect, the more the merrier, but four is a good number, and from what Ive read on the other forum I told you about, four is the least you should go with.

What other tankmates are you planning to keep in the 40 gallon, with 5 discus? They really dont like nitrates much over 20, so you may end up having to do more water changes then 50% 2x/week with 5 discus

Good Luck

 

Thanks Tom, I have read so many conflicting reports about the nitrates and there levels with discus, before coming here.

I have to admit I am good for overfeeding, and Im still working on it.

I guess I was always under the impression that once the filter is established the only thing left to watch is the NO3. I know NO3 is the least toxic out of the NH4, NO2, and NO3.

My tank usually reads 20-40ppm of NO3, and I always felt the plants didnt use the nitrogen properly...so I guess I really need to watch my feeding from now on

Sorry cazandchris if I gave bad advice....Im now going to do 40% 2x/week WC's

Thanks for the info Tom.

 

A 40 gallon tank, for discus? I'm pretty sure I have been reading here and other places that discus need more room than that. Also, they need to be in larger groups for social reasons, and 40 gallons is far short of big enough for a school of discus, except perhaps as very young fish. What am I missing here? I gave up the idea of discus in my 45 gallon tank just because of that reasoning.

 

Is there a thread anywhere on this site about how to "sterilize" an old reef tank and get it ready for a planted freshwater tank?

There is a 75 gallon old reef tank at work, and the guys said I could have the tank, stand, and light fixture for free!!

The tank has been out of commission for quite some time now, but still has pink, purple, and white crusty stuff all over the glass. It has a leak too, but one guy said he will re-caulk it for me.

Thanks very much

 

All I did to clean my ex-reef tank was wash it out with lots of water and a sponge. I did have to scrape a few minor places, but mostly the salt deposits just dissolve off. I rinsed it a few times with more water, and that was it. Even if it takes you a few hours to wash it out the price is still as good as it gets! Just don't forget that you will still have to buy lots of other stuff before this becomes a planted tank.

 

Thanks VaughnH....I was hoping everything I had and use now would be ok to use in the 75? I wasnt going to keep the 46 after I made the switch, so pretty much everything in my signature would go on the 75.

Your thoughts?

If I should start a new thread...I will?

Thanks again
Eric

 

Since you can just switch equipment to the larger tank you really do have a bargain! I don't see where there would be a problem, the filters are certainly big enough. You might need a different CO2 reactor system, but everything else should work fine.

A new thread would have been better, but I don't see any harm done.

 

Thanks very much VaughnH

 

Vinegar will help remove calcium deposits...bleach works for sterilizing. Using dechlorinator on your final rinsing should eliminate any bleach residue. Or just let iet dry out good and any leftovers will evaporate.

 

Tom,
Was that discus raised in that tank? ITS HUGE!!!!

 

Without Discus in my planted tank, I would do a 50% WC on a Sunday. Then finally adding KNO3 and KH2PO4, CaSO4 and MgSO4.

Now, you are recommending to do twice 50% WC weekly. Suppose I opted to do the 2nd WC on Thursday. Then I will as usual add KNO3 and KH2PO4. Am I right to say that I should also add in the CaSO4 and MgSO4 ?
