Chalakudy River, Kerala

Sponsored by

India, Kerala, Thrissur District

This BAM replicates the natural biotope of one of the numerous tributaries of the Chalakudy River, Western Ghats, Kerala, India. Chalakudy River is the fourth longest river in Kerala and is well known for its fish diversity and thick riparian vegetation. The rivers of this region are rain-fed, so they undergo many changes in depth, temperature, water chemistry, flow rate, and so on. Where the riparian vegetation is absent, the bottom of the river consists of rocks and yellowish sand.

This biotope is based on a clear water small area of a tiny affluent of the upper Chalakudy River, near to an authentic view of a still bank region.

Many different fish species live in this biotope, to name a few: Haludaria fasciata, Devario malabaricus, Mastacembelus pancalus, Opsarius bakeri, Carinotetraodon travancoricus, Eleotris fuscus, Garra mullya, Mesonoemacheilus guentheri and Mesonoemacheilus triangularis, Aplocheilus lineatus, Esomus danrica, Pseudosphromenus cupanus, Rasbora daniconius, Puntius vittatis, Pethia ticto.

Aquarium information

Aquarium description

Set-up date
2009
Aquarium decoration

The biotope aquarium was decorated with very fine white sand, some whitish rocks, small gravel in certain areas, small pieces of driftwood and leaves on the ground.

Aquarium equipment

The JBL-canister filter was used for water filtration.

Fish care

The fishes used from this habitat live in slow-flowing water. In areas of the Chalakudy River with strong flow live different species; different ones live near the Indian Ocean, and still others in the Chalakudy rapids. It is important not to have bright lighting all over the aquarium, and CO2 is not necessarily needed for this kind of biotope.

The fish species in the aquarium are Haludaria fasciata, Devario malabaricus and Mastacembelus pancalus.

Plant care

Some plant speceis were included in the biotope aquarium, that is Hygrophila difformis, Hygrophila pinnatifida, Hygrophila polysperma, Hygrophila involuta, Bacopa monnieri, Eleocharis acicularis and Myriophyllum tuberculatum.

Water care

Water parameters are: pH 6.8, conductivity about 170-180μS/cm, and temperature 28 °C.

Comment by the expert

Petra has created this authentic habitat, for which I was able to give some advice. I also judged the preliminary JBL-Biotope Contest on line, which she had entered with a beautifully decorated biotope aquarium from the upper Hong Kong region, and with the latter she won the 1st prize for Eurasia, and became one of the 5 finalists.
