Creek in Pandaan Pasuruan, East Java, Indonesia

The biotope I recreated this time is a mountain stream in the Pandaan area, Pasuruan, East Java. Although this is a small stream, the current tends to be very fast, which is the habitat of such a fast-swimming fish as Barbodes binotatus, Mystacoleucus obtusirostris and others.

This river interested me also because it is the habitat of a very beautiful Rhinogobius sp. which looks like Rhinogobius similis. This fish is still often found in some regions of East Java, such as in Mojokerto, where mountain streams always have this fish.

Hopefully this biotope aquarium will inspire others to recreate a habitat for Rhinogobius sp. fish in the aquarium.

Aquarium information

Aquarium description

Set-up date
February, 2023
Aquarium decoration

I used river stones taken directly from the location, and added roots and branches like in the natural habitat. For the aquarium background I used river art print paper. I put the aquarium lights in a position that can make a light effect like when diving in a river.

Aquarium equipment
  • Spotlight Kandila 1M used for the effect of sunlight
  • Gutter filter filled with sponge and synthetic cotton Pump engine: takari 1800, 1600 L/H, 30 Watt
  • Wave Maker Recent AA WM 24000, 24000 L/H, 25 Watt for use once a week once a day, fast water mode
  • Kandila S500, Spotlight Kandila S200 used for the effect of sunlight.

Fishes:

  • Puntius binotatus (Cyprinidae)
  • Rhinogobius (Oxudercidae)
  • Mystacoleucus (Cyprinidae)
Fish care

I make enough room for the fish to swim and feed. I also make cracks for the spawning places of all the fish in the aquarium (can be seen in the video). I keep the water temperature low at 22-26°C.

Plant care
Water care

20% water change once a week.

Comment by the expert

Heok Hee Ng: Rhinogobius is not native to Java, so this is a poor choice for this biotope theme (you should be using Stiphodon, Sicyopterus or Awaous instead).

Greg Martin: Almost faultless – well done.
