Hi team I'm feeling discouraged with unexplained cardinal tetra deaths in QT. link here: Help - 4 Dead Cardinals In Qt - Why?!?!? If the remaining 3 (or 4 but I'm not optimistic it's alive) die, then here are our options: wait about 3 wks & try again with a big school of cardinals in the 65L QT once we add the current cichlid occupants to their DT. or opt for a different 25-26.5ºC tolerant nano species. Here's what's NOT available in NZ: chili Rasbora CPDs neon Rasbora most killifish besides gold panchex or sometimes chocolate killi most other nano species like lower temps. Any ideas or comments from you lovely people?
