Tiger Barb is one of the most socialised fish in the world but known among ornamental
fish for its’ own aggressiveness. 8 males and 16 females Tiger Barbs were carefully
chose and placed in 4 tanks with 4 divided section that contain a breeding mop in
each section to observe and identify the fishes’ colour preferences on breeding mop
as alternative to the real aquatic plant. The schooling site and section preferred by
the Tiger Barb were observed every day at 10.00 o’clock in the morning for 21 days.
The water quality such as potential of Hydrogen, temperature and Total Dissolved
Solids were also recorded alongside the main method. The results showed that the
most preferable colour of breeding mop was dark green. The potential of Hydrogen
range (pH6.67-7.10) could drop to pH6.34 without aeration, temperature range (27.8-
28.9 celcius) and Total Dissolved Solids range (15-21 ppm). Dark green colour of
breeding mop was suitable to use for Tiger Barb breed in this water condition.
