De ceva vreme frunzele superioare ale nucusilor din acvarius sunt "arse". Nu-si schimba culoarea ci apar doar ca niste foite de plastic de care apropii o flacara.
De la ce ar putea fi?
ciudat este ca celelalte plante nu par catusi de putin afectate, in masura in care nucus-ul este planta cu cea mai buna dezvoltare din acvariu si careia pare sa-i priasca cel mai mult.
