Depinde ce vroiai sa tii ,pot sa-ti spun ca nemtii(cei mai mari crescatori din europa nume ca Stendker,etc) cresc discusi in apa foarte dura -la noi e doar in Constanta asa ,dupa cum spun constantenii la robinet la ei curge aproape nisip si se cresc discusi si in Constanta in apa de retea ,sigur le reproducere e alta poveste dar puietul e crescut tot in apa de la robinet :
""Our discus fish, however, have been accustomed to harder water (tap water) for many breeding
generations. The water chemistry data in our hatchery is: general hardness: GH 15, carbonate
hardness KH 8, pH value 7, conductivity 800 ?s, water temperature 29° – 30° C / 84-86°F.
For our discus fish, the key water parameters have the following tolerances: GH 0 – 30, KH 0 –
25, pH value 4.0 – 8.3, electrical conductivity 150 – 1200 ?s. Tolerance for short-term water
temperature changes: 25° – 34 ° C / 77 - 93°F.
This means our discus fish are suitable for over 95% of all types of tap water in Europe."
Asa ca inca o data depinde ce vrei sa tii, sigur pesti wild caught din bazinul amazonului nu merge sa tii in apa de Bucuresti der domesticii in general da, vezi in topicul "Un strop de caldura" colegul johnny tine arowana-55cm si chitala 2 bucati de 50 cm in apa de Bucuresti
