Discus aquarium stocking question (what is too much) ?

[Colin_T]

Keep all the discus at this stage because the more you have, the more chance of getting males and females. As they pr off you can get rid of some if you like.

Discus size will be limited to tank size. If you put the same fish in a tank/ pond that was 6 feet high x 20 feet square, they would hit 10 inches in 2 years. In a 6x2x2ft aquarium, they will hit 6-8 inches in 12-18 months if fed well and in clean water.

Then again, I could be completely wrong. If they are juveniles, there is a chance you will lose some. It happens. So maybe starting at 10 and thinning out the easier to find other fish might work.

Not to mention the occasional sociopath. I've had to remove overly aggressive discus.
