Minimum tank size for 4 discus

[OnlineFishTank]

Sorry for the newbie question, but what would you recommend be the minimum tank size for 4 adult discus?

Thanks, Chris

it's usually 10 gal per discus. four is not a good idea. discus are a very social fish that do best in groups of six or more. not saying it can't be done, but in most cases there will be an aggression issue which can lead to sickness and/or death.

I agree with above poster but if had to be done, then I would think at least 55 gallon for 4.
But pH should be low with softer water so your water conditions should also be considered in keeping these fish. They are best left for the experts.
