I'm starting up a 46-gallon and have plans to build a tropical community. I want a school of rasboras and a school of tetras, as well as a "centerpiece" fish. Would a discus do well in a community? Is it OK to keep one discus?

pH is 7.8, and the tank will be cycled.

Thank you!

I would say No because they need a minimum of 5 to school/shoal and they like VERY acidic water. FYI, They are a difficult fish and for the "experienced". Here is the old profile for them to read up on. I'm not sure where the new one is and I'm pressed for time. Hope it helps.

Both SeaHorse and jaysee have made excellent points. A discus isn't for your tank.

However, have you thought about gourami? Dwarf gourami come in colors comparable to discus. Honey gourami are also rather attractive.
Thank you guys for the advice!! I'll stay away from discus. :)

What do gouramis look like, and what are their care requirements?

In a tank of your size you can try a pair of 3 spot gouramis or 3-4 pearl gouramis (one male). They would be centerpiece fish. They are the largest fish I would put in that tank. There are several other types of gouramis you could do, such as moonlights, thick lipped, banded, dwarf and honey gouramis. Of course all may not be available to you.

Their care requirement isn't really any different than other tropical fish.

The Blue and Yellow are the same species, those and even with Pearls, one of the gentler Gourami, I have found that a tank (even my 75gallon) could only keep one Gourami in the tank at all. Many on this site have been successful. It depends on the Gouami itself, some are quite the bullies so just an FYI. Also many LFS can't sex a Gourami or only carry the vibrant males anyway and that's where a lot of the trouble comes from. Tanks are too small to create ample territory for more than one male. Even one Gourami would be wonderful in your tank tho! and don't need "companions" of their own kind. You may find you'll buy 3 and end up over time with one left who will not tolerate any new ones coming into the tank.
I currently have 3 Honey males in a 10 gallon, currently getting along, but at least one maybe 2 will have to be moved to the 75 if or when they start harassing each other.

You should always be responsible for sexing the fish. Know what you're buying, whether it;s a fish, a TV or a car :)

Gourami have the same care as the other fish you've listed for your tank. You won't have to change anything like you would for discus.

This is two male dwarf gourami sparing:



As SeaHorse said, you'll want to have a backup plan in case you get an aggressive one. I have one in my 29 gal; she's significantly more aggressive than the male. A backup plan can be something as simple as knowing the return policy of the store to having another tank for the aggressive one. Observing the fish in the shop tanks isn't always the most accurate because of the substandard conditions they are housed in.

If you get gourami, don't play games, get chocolate gourami.



As for discus, if you have a ph that high outta the tap there are ways around it. The right amount of driftwood can substantially lower your ph and with weekly 10% water change you can keep the water clean without shifting the ph at a high volume.

Chocolate gouramis are the most difficult species to keep. Not a beginner fish at all.

10% water change is not anywhere near sufficient.

Pouring powder into your water while doing your wc isn't exactly rocket science though, even for the beginner. We run everything from super low ph apistos to super high ph calvus and everything in between all off the same tap. Mostly without using additives aside from dw and aragonite.

I over filter hard with basically all canisters loaded with bio media but I only do 10% weekly or 25% bi weekly. Granted I cycle correctly and build up the stock level as time goes on. Never had rapid fish loss or a disease outbreak that wasn't caused by me being stupid and bringing in an unquarantined outsider. If it were to be a couple discus in the tank and you followed the standard over filter rule for cichlids as they are I personally think levels would stay healthy. If it's a garbage filter and there's over feeding going on in an overstocked tank, maybe not so healthy.

the discus is so difficult to take care of , i didnt change my water for 3 months, i left dead plants in my tank, filter pads weren't changed for months
. I fed them more food than a food bank actually has.
But now i turned my tank around and i have privately bred plants with an auto drain mechanism so im changing water every 3 days.

Dont ever listen to what people have to say about easy fish and hard difficult fish. as long as you change your water and have correct filtration and your not overfeeding you will be fine with a discus fish.

Discus do need company and your tank really is too small for a group of them.The suggestion of Chocolate gourami was ridiculous and should be ignored. A realistic choice may be the thick-lipped gourami, not as popular as some but that lack of popularity has left a fish less inbred and much more predictable in behavior. Good Luck

I don't know what it is with yall and thinking chocolate gourami are difficult to keep. You can keep any fish you want Ivan, and you can create any water conditions you would like with limited amount of effort. Find what you like, do your research, make the proper preparations.

done.

Getting back to the OP, what kinds of Rasbora and Tetra were you looking on stocking?

I think Lemon Tetras are a good option for your water based on the ph (do you know the numbers for gh/kh?), but Rasboras generally prefer softer water. What about Cherry Barbs? They're bright, active fish.

If I had the option I would totally go for Cherry Barbs. They're such gorgeous, fun fish that are easy to care for.

This is not true in the slightest. Discus require a large tank in the region of 75-90g as they get large when fully grown. The advantage of also keeping them in a larger tank is more stable water parameters. Having correct water parameters is more important than filtration. Many people over filter with discus, however this sometimes makes the flow too much for them.

I do have to agree though that this tank is too small to keep them to adulthood. Minimum shoals should be 5 fish with smaller species as tankmates, this makes it overstocked in a smaller tank.

Now some species to look at instead of Discus are Peacock Gudgeon, Red Honey Gourami, Dwarf fire Gourami, Harlequin Rasbora, Sterbai Cory (as bottom feeders) and Electic Blue rams.

I must ask though as no mention is made of it. What are your water parameters direct from your faucet / tap? This will play a big part in what can be stocked in your tank. Changing water parameters is not an easy task and depending on the parameters from the faucet / tap require a large investment to keep them in check.

The Original poster came here to ask for advice, NOT have users shoot them down, please kindly stay on the thread with no snarky or rude comments.

if you are a beginner then i won't suggest you to keep them.Discus are hard to keep and should be kept in a group of 6 or more...

Just tested my tap water parameters. I was very surprised to find that ammonia was at .25!! :shock: I did not know tap water could have ammonia! Here are the full parameters:

Ammonia: .25
Nitrite: 0
Nitrate: 10 or 20 ppm (I cannot distinguish the two colors on the chart for the life of me)
pH: 7.6

What are GH and KH?

Will it hurt my fish to have ammonia in the tap water? I am using Prime, and it says on the bottle that it detoxifies ammonia.

I haven't decided yet! I know I don't want harlequin rasboras, as I already have some in my 10-gallon.

As for tetras, I really like neons. I'm also looking at blackskirts. They're gorgeous!

What do you think?

Thank you all SO much. It is so wonderful to have so many people chime in. :)
