- one of the lowest requirements of care of any
tropical species;
- well filtered, soft and slightly acidic water at roughly 28C
is preferable;
- in captivity to be kept in a wide
variety of conditions ranging from a PH4 to PH8 and KH2 to KH20...depending on specific fish and its tolerance to the environment but...are very hardy;
- (so,) ideal conditions are based around sensitivity to PH and we
always recommend owners keep their tanks as close to PH6.4 to PH6.8 as
possible;
- exceedingly tolerant of poor conditions, they
are not however tolerant at all to changing conditions. The greatest risk your
Arowana will face is a change in environment such as changing the filter, or
overfeeding a tank that has too weak a filter (which) can cause a spike in
ammonia, nitrates or nitrites;
- It is not the conditions themselves that can be
harmful but the change which may result in losing your fish;
- A clear example of this is a tank that has been poorly kept
for several months. The owner decides to perform a 60% water change with the
purest, most perfectly conditioned and correct water.
- As a result the Arowana
becomes unable to swim correctly, starts to rotate in the water and over a week
dies. The issue is not the condition of the water but the unexpected change; &
- (so,) this same change could be achieved with 10% water changes per week, or even a
reduction of the water level and a drip fed increase over several weeks.
