Anubias Rhizome Rotting!
TANK DETAILS: 38 Gal(US), pH 6.8, KH 3, RUGF, no CO2, 80 W (triton),
plain gravel substrate, moderate/densely planted (depending on your
definition) and is established 3 years. The set-up is lo tech but
growth have been satisfactory for a variety of common plants.
Fertilisation has been casual for the most part, but I have been using
a trace element mix 3 times a week for the last 12 months.
PROBLEMS: Anubias are my favourites, I have 4 types A. Barteri, A.
Barteri var. nana, A. Congensis, A Coffefolia (sp.?). The nana is the
best established and has been present since day 1, it covers about 60%
of the gravel surface. They are having problems. In places the rhizome
has rotten away completely in small areas 10-20mm, the plant on either
side of the rot seems to be OK. The rot appears on many Anubias plants
and all 4 types. Is this an infection, a result of some deficiency or
a method of vegetative reproduction..... anybody?
ASIDE: Measurable water conditions have not changed much for years but
most of my duckweed has disappeared also.
