Madagascar is a large island in the Indian Ocean off the south eastern coast of
Africa. This island hosts many
plant,
fish and animal species that are purely endemic to it. It was originally joined to
Africa but split away 160 million years ago. A lot of the current habitats are under threat as more and more of the natural landscape is being converted to paddy fields for the cultivation of rice. As deforestation is occurring at a fast pace erosion is starting to increase along with the introduction of exotic
fish species like the snakeheads and mosquito
fish, the endemic species of
fish are starting to decline rapidly. Some of the species are even thought to be extinct as no reported sightings have been made for several years.
Tilapias were introduced to the rivers and streams as a
food source but due to their aggressive nature they have displaced many of the native cichlids.
Setting up the biotope
The recommended size
tank for this
biotope is at least 100 L (22.0 gallons). On Madagascar the
water is hard compared to other regions, 8-19 DH with a
pH of 7.0-8.0.
Temperatures should be set between 24-29°C depending on the livestock you are adding. Due to the large
temperature range always research the
fish you are going to add.
The rivers and streams on Madagascar have sandy
substrate with earth banks and lots of
plant life so the
substrate should be fine silica sand or fine
gravel.
Lighting should be bright to give the desired effect but a steady current in the
water is needed so it is advisable to dampen down the
water flow on the
filters with spray bars if possible.
Suggested plants for the biotope
Background to middle planting can be achieved with Aponogeton Bolvinianus, this can grow quite tall, up to 30” in its own habitat but in an
aquarium it rarely exceeds 20 “.
Bacopa Madagascariensis also makes a great
plant for the middle of the
tank, but reserve a place in the middle for a specimen
plant like Aponogeton Madagascariensis commonly known as the Lace
plant. This is getting hard to find in its own habitat but they are available to buy, the shortage does reflect on a higher price though.
For the front of the
tank add some clumps of Blyxa Auberti mixed between random pieces of
driftwood.
Another good specimen
plant is Cyperus Alternifolious; also know as the umbrella
plant. This is closely related to papyrus and can grow quite tall.
Suggested species of fish
Bedotia Geayi is a rainbow
fish that is endemic to Madagascar, commonly known as the red tailed silverside. Adult size of this
fish is 3.5 inches and it prefers temperatures around 24°C.
Cichlids like the Paretroplus family can be added, there are a few species of these to use but these may need to be ordered from a specialist supplier.
Killifish are a must with their beautiful colorations, lots of variations to choose from and easily available to purchase.
Freshwater gobies are found everywhere in Madagascar, brackish species are also to be found in the
river tributaries.
If you are planning to add cichlids from other areas of the world, research them first as they may attack or even eat the smaller inhabitants of your
tank.
