They should be in a tank sized for them as adults, growing in too small of a tank can cause health issues. None of the fish you listed are going extinct, they'll be around when/if you decide to put in a tank large enough to hold them.
But that side, you say the tank has been running for 1 month? Did you cycle it before adding fish?
Discus are an extremely sensitive fish to water parameters, best only added to a well established tank. They also need pretty specific water parameters so we still need to know Ammonia, Nitrite, Nitrate, pH, and GH at a minimum.
A single Clown Loach is also asking for trouble, read up on their profile as well. In addition this tank is far too small for them.
