I currently have Crypt. lutea & wendetti, E. bleheri, E. tenellus, Hygrophila difformis, Anubias barteri nana, E. foxtail, E. stellata, Sagittaria pusilla, Rotala rotundifolia, Hygrophila corymbosa Kompakt, Hygrophila corymbosa glabra, Limnophila sessiliflora and Alternanthera reineckii.

Tank temp varies between 27C and 28.5C.

I've had issues with some of the plants but due to deficiencies, not temperatures. And definitely not due to the three Discus.
