what r the best tankmates for discus i have a 4 foot tank with 1 brilliant red discus, 6 harliquin tetras, 2 wild honey gouramies, female krib, 2 bristlenose, i was thinking of getting 2 angles, 2 rams, 1 male krib and 6 congo tetras and maybe a few cardinals. my male discus never lets other discus survive in my tank iv added 5 but he killed them 1 by 1 what do u think will work hes fine with other fish that look nothing like him self.
 
I would really get some more discus. they do alot better in a school more then 5. I have 3 and they are very very shy because they are not comfortable..
 
i added 5 at the same time so there was 6 in total and he killed them all. 1 by 1 they where all the same size as himself
 
how big of a tank is this?

i would say do not get a male krib, they are really aggressive when they are spawning. they WILL attack discus. rams, tetras, south american plecos. siamensis are good, otos are good,

you either got an aggressive discus or youve got a bunch of weak ones. i had a discus that would attack the others,finaly they turned on him all at once.
 
discus do best as a group of 6-8 in a tall species tank. water temperature of 80-85° and NO other tankmates.

Discus do fine with tankmates, though good tankmates can differ due to size of tank and their personality.
 
kribs are african, so they should be removed, gouramis are from asia so they should also go. no angels or congo tetras. you should add to the school of harlequin rasboras (they arent tetras) as they do best in schools of 10-12. cardinals would be great but you would need a school of at least 6, not just a few. the temp shold be at 86 for discus. you may want to consider a school of cories, they do great with discus. go with a smaller species, not one of the ones that get to be 3" or more. how many gallons is your tank?
 
We have 2-4" discus(Hopefully a PAIR?) with cory cats(adolphi), blue & gold rams, a 4" geophagus juripari(probably swap him for a red hump him as he gets bigger)and a small school of rummynose tetras. The rummynose are a great dither for discus. And their colors are a good indicator of tank conditions. If they start losing their red noses the water quality is deteriorating, check it! They'll go bad much quicker than the discus so you have a good heads up to keep the big guys happy.
 
how big is this 'loner'..if you add other discus they should be the same size. if you have a large discus and you add small discus..you could have problems. discus will establish a pecking order. an lone large discus could pose a big threat to smaller discus.

you say 4' tank.what is the water volume..I have 3 4' tanks.1-55, 1-75, 1-110.

discus generally do best in schools/shoals of 5 (but this is a general rule).

you can raise angels with discus..but manydon't suggest it..make sure tha angels and the other fish have been placed in quarantine..
 
I'd suggest discus only bare bottom tank...but thats just my preference with my discus. But if you do want some tank mates, i'd suggest some small schooling tetras, apistos, and some dwarf plecos (be careful with them though....sometimes they will suck the sides of your discus...not a good thing). About your dominant discus...when you get new discus, take him out rearrange the tank, add the new discus in there for a bit then add him lastly....may give the others a better chance...or if you have a place to house him for a few days it would be even better....let the others establish themselves then he will have to assert himself in the pecking order.
