    They will continue to grow but probably at a slower rate. 15 adult discus would need around a 180 gallon + tank but even if you're not keeping all you should definitely increase your water changes to 100% daily or even more so. You don't want to risk your fish getting stunted, there isn't any coming back from that. If I was in that situation I would be doing at least a 150% daily.

    How can someone afford that many discus but not a proper sized tank for them? Maybe they're just more expensive where I am compared to the OP (no clue because location is not listed). Or does it just really depend on the size when purchased? It just seems crazy to me to have that many discus in such a tiny tank. Even if one does not care about the health of the fish (not accusing you of it, just a hypothetical example), I'd expect one to want to protect their investment.

    Are you using RO water for your water changes?

    2inch and smaller discus are relatively 'cheap so a lot of people see them as an opportunity to get into discus but a lot of work is needed'. RO water is not needed especially when it comes to growing out discus. They grow faster in water with higher tds.

    Judging from the name OP is Indian. They approach things differently and seem to prefer very densly stocked tanks.

    I read in an article that a discus keeper kept grew his fish in a small tank but did frequent water changes throughout the day, after every feeding. The fish grew very well but who has the time to change the tank water 100% 5x a day?

    You could automate that I suppose.

    15 discuss...I'd be looking at a 5ft tank if I wanted that. Minimum!

    Unless there is no room, keeping such a small tank creates vastly more more work considering the number of near 100% water changes that would be required to even try and get these discus to a non-deformed shape; I can only assume they are not aware of this if they don't want small, deformed fish. The 50% daily W/C is not gonna cut it at all as the fish grow. Might not be doing well even now. Can't see how any filter on such a small tank will keep up neither with just one W/C a day. Wonder if they even measure the water parameters?

    Of course, this could be a troll just trying to get attention; that is, unless this is just a first time person with zero knowledge of fish keeping.

    Knowledge is fun(damental)

    A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

    At the 2in stage, a 55gal bare bottom is the general recommended tank. I hope you are indeed planning to get into a 180 tank or so for these fish. The 100% on grown better with high tds but I would be doing the same as recommended, 100% w/c in the morning, 50% that night. That is a lot of work... I do 90% daily for my mated pair of discus. As far as growth, you are going to see an easy inch on those fish if they grow at the normal rate.
