Overly aggressive Discus

Have you got something in the tank for structure?Big tall red clay pot.If they are newly aquired keeping the tank lights off might calm them down until they get to know each other.Two males might be a constant problem.
 
You need to add more discus ASAP they will kill each other fairly quickly 3 is the worst possible number to be keeping.

I recommend 1 or 5 or more discus nothing in between

I would not separate them. It is all normal behavior amongst young discus. I went thru this with the last 2 I purchased. It started while they were in QT together and continued when I put them in the tank with my adults. It was always the same one doing the chasing of the other one. I've had them about 9 months now and they are just starting to mellow out and swim together. I was always afraid that the one being chased would stop eating and sulk one day, but he didn't. And now they're fine together. Just had to get them over the growing up period!

Many thanks for this quick response, yesterday whole night I observed their activity seems your word is very true. If any thing goes wrong I shall post. -avi.
 
Not to jack your thread, but I've had similar problems with four discus. Two are 3.5 that I've had just over a year and two juvies 2.5" that I've had since the first of this year. The juvies are eating and swimming with the others, but one in particular is getting bullied and is showing it in nipped fins. It doesn't stop that fish from being social and eating, but I'm worried about what is going to happen.... any thoughts?
 
I would say just let it be. I know you have to hold your breath and hope that they work it out.
 
I bought a pigeon blood and wild type juvies out of the same tank. At the lfs, the pigeon blood was the biggest and bullying everyone, once i got them in my 180 with 4 angels, the wild started schooling with the angels and started picking on my pigeon blood....its not too bad yet, but i am adding more discus as i can afford them. And i was worried about the angels. lol
 
Pink, you are perfectly right

Pink, you are perfectly right. The problem that I had earlier, that is no longer there. One more conclusion is that "Stress Bar" is not necesserely ment for any stress, I feel it is totally depend on their mood. Any idea you can add on this issue. By the way recently I have added 2 more yellow face super red melon (1.5 "), they are also doing the same thing as other two did. Is it pair like behaviour? At what size they are ready for making a pair? Please let me know. Thanks. :iagree::iagree:
 
Glad to hear your earlier problem is gone!!!:thm:
And you are correct, stress bars are also mood indicators too.
You are not seeing pairing behavior in your 1.5" discus. You won't see that until they are at least 8 months old and much bigger. You're just seeing the feistiness of young discus.:)
 
Hi Pink, I have to disturb you again, my one leopard discus 3.5” in size, suddenly became dark form yesterday night, took very little food. Garlic extract is not available in my country, so I made the same thing manually by crashing garlic. Simply I lost my way, I can’t find any please help. Tank status : 20 USG, Temp : getting too high on day due to heavy summer (36C to 37C), few times I use little ice to reduce it to 31C to 33C. Stock : 2 leopard (3.5”), 2 melon (1.5”). All are well enough except this one.
 
I had a simlar problem with 2 mated pairs every thing was fine and then one of the females picked on the other and left scar tissue over one eye, I quaranteened her and have tried on 3 diffrent occasions to put her back each time she gets attacked.

Yet the 2 males and one female are fine............it's frustrating but that is the fun of keeping Discus.
