One of my favorite Tetras, these guys look amazing when fully grown. When young they can be susceptible to whitespot, But I believe that comes down to water quality. This Tetra should be treated like Cardinals or Rummy Nose Tetras, good water quality, regular water changes and a very good filter. Be careful of Nitrates.
pH - 6 - 7
GH - 50 - 100
Temp - 26 - 29c
Remember the water quality...And they seem to prefer a darkened tank, adding Black Water concentrate is beneficial.
