MEET AN AQUARIST SERIES: THE AQUARISTS OF BANGALORE

PART TWO: MADAN SUBRAMANIAN


   Madan Subramanian likes to be surrounded by water! For six months at a stretch he is Chief Engineer of a 300,000 ton tanker carrying crude oil over the oceans of the World, and during his six months off duty he takes care of his aquariums at home in the landlocked city of Bangalore. Bangalore is a centre of a growing computer based industry, and is also known as the "Garden City" of India. To reach Madan's house in the suburbs we drove along wide tree-lined boulevards, which are zealously conserved by the City.

   The lights of Madan's spectacular six feet long aquarium are visible from the street through the latticework of the large front balcony on which it sits. As is normal for keen aquarists in India, Madan built this tank himself, using glass cut and ground to size by a glass company. It is held together by silicone, without a metal frame. Its stand and canopy were custom made of wood to match the built-in cabinets of the spacious marble-floored living room where it was originally kept. But it was found to be a little messy so was moved just outside onto the adjoining balcony, leaving the elegant room to Madan's collection of objets d'art from his World travels.

   Madan's main interest is growing aquatic plants, and to this end the tank is lit eleven hours per day by seven fluorescent tubes, is filtered with an Eheim P11 canister filter, and is supplied with CO2 from a
12.5 kg.(27.5 lbs.) cylinder. In Bangalore's warm climate, heat is only needed for a couple of months of the year at most. Madan's collection of plants is indeed World class, and he supplied me with a list of the Latin names of thirty four plants he currently keeps:

Echinodorus bleheri, Echinodorus "red flame", Echinodorus Rubin "narrow leaves", Eustralis stella, Hemianthus micranthemoides, Hydrocotyle verticillata, Lileopsis brasilliensis, Lileopsis mauraitania, Echinodorus tellennus, Saggitaria sp., Vesicularia dubyana, Microsorum pteropus, Microsorum pteropus"Windelov", Microsorum pteropus "narrow leaves", "Christmas moss", Bacopa sp., Vallisneria spiralis, Elodea densa, Rotala sp., Eleocharis acicularis, Cyperus helferi, Blyxa sp., Cryptocoryne wenditii, Cryptocoryne willissi, Cryptocoryne willissi " lucens", Cryptocoryne becketti, Cryptocoryne balansae, Nymphea sp., Hygrophila sp., Crinum calamistratum, Alteranthera sp., Ceratopteris thalictroides, Heteranthera zosterifolia, Ludwiga repens, Anubias barteri, Anubias barteri var."nana", Anubias afzeli, Anubias caladifolia"1705", Aponogeton ulvaceus, Rotala wallichi, Ludwiga grandulosa.

   As an engineer Madan naturally takes a high-tech. approach to their propagation, and is keenly interested in such matters as water quality, lighting, substrates, and fertilisation. He searches and contributes to the Internet about the latest ideas on these matters.

   The tank does of course contain fish - a community of tetras, rainbows, platies, Otocinclus, flying foxes, guppies, gouramis and corys.

   But the most interesting fish was one that I had not seen before, "Denison's flying fox" or the "red line torpedo fish" (Puntius denisonii, formerly Barbus denisonii Day 1865, and Madan also referred to it as Crossocheilus denisonii - there is still lots of confusion over Indian fish names!). This fish resembles the Siamese algae eater in shape but is far more colourful, with beautiful red and yellow stripes on its body and fins. It is in fact a barb, and is omnivorous.  It likes to swim in groups and is peaceful and non-territorial, and grows to about 16cm.  It is a jumper and should be in a covered tank. One of my Indian friends once had one jump five feet straight up out of a bucket - he caught it at eye level!  Later I took the trouble to seek out the wholesaler, in Madras, and was told that it is only available seasonally, being caught in the wild from fast flowing hill streams in South India. (It thus requires a well oxygenated tank and will accept cooler temperatures). It has not yet been bred in captivity and I do not know how many are left in the wild, although Madan told me that it is not on the endangered list. (December '02: I just came across a list in an Indian web site http://www.ornamentalfishes.org/html/family.htm that says that this fish is endangered, but "sufficient quantity is available for commercial exploitation"). Particularly if it could be bred in captivity*, it would be a wonderful new barb for our aquariums. It has recently been imported and sold in North America, at a price of US$30 - 40, and some were sold in Germany in 1997 and in England in 2003.
* October 2003: I am informed that this fish is now being bred commercially in Singapore and Indonesia, possibly using hormone injection methods. It is said that the colours of these fish are not as vibrant as the wild ones.
November 2003: This fish finally made it to Vancouver Canada! Big Al's Aquarium Services imported seven from Singapore. When I saw them there were four left, which I bought for a total of about US$95.

Puntius denisonii, or Barbus denisonii

   Beside the main tank are two smaller ones of about 40 gallons each. These are also supplied with C02 and are well planted. When I visited in January 2002 Madan was not due back at work until May, and was starting to set up another large square-shaped   tank. He had also begun work on his own web page, and hopefully we shall be able to see photos of this tank in due course.

   So who looks after the tanks when Madan is away for six months at a time?   - his wife Gayathri of course!  When they married in 1991 Gayathri had not the slightest interest in aquariums, but she now does a very good job with no disasters yet, helped sometimes by Madan's instructions over long distance telephone lines.

Raj Kumar told me of a young man he knew who seemed to be able to breed any fish he tried. Adip Sajjan Raj is an electrical engineering student who had to sit an important examination on the morning of my visit. Madan made several calls on his cellular phone and after lunch we finally went to the house where Adip lives with his family…
