Count Dracula the Vampire Crab Joins Us for Lunch
Count Dracula, our Vampire Crab joins us for lunch. He has glowing yellow eyes and a creepy walk, and spends most of the day under his favorite rock. He is a fussy eater, and has his own menu. While we eat our boiled Sweet Potato and stir-fried Kangkong (Water Convolvulus) with Ikan Bilis (Dried Acchovies) and Sambal Belacan, he is eating Hokkaido Moss Ball on Ice, UHT Black Mosquito Larva, Freeze-Dried Hook Shrimp, Coral Shrimp, and Frreze-dried Antarctic Krill Pellets.

The Sulawesi Freshwater Leopard Crab
Sulawesi Panther Crab a.k.a. Leopard Crab is a freshwater crab from Lake Matanao. It is a beautiful creature with a fascinanting personality. Lake Matano is a deep lake formed from the crater of an extinct volacano. At 500 metres deedp it is the 10th deepest lake in the world. Another species of crab, a cousin of the Leopard Crab , the Pruple Matano Crab also lives here. This crab is the Cheetah of the Crab world, its movements are so fast that its a problem to catch them when changing the aqurium water When the Crabs first came they were small and had no spots, with the suitable tank water conditions and frozen blood worms fed to them, they are now thriving and the spots began to show. Will give them the care they deserve. Like the Crayfish that I keep, Crabs also molt. When they grow too big for their skins, they change to a new skin. But unlike Crayfish which often die in the strenuous effort of molting, and leave a messy old skin with parts missing, Cr...
My Crayfish Died While Moulting plus Crayfish Gallery
Crayfish moult approximately every month or so. If they are in a tank with other Crayfish, they are most vulnerable during the moulting process which may take up to two hours. Unless they are in a sheltered nook, the other Crayfish may attack and even eat her. After moulting, the shell is soft and takes a few hours to harden. This Female was literally 'frightened out of its skin' by an aggressive Male, and could not complete the moulting process.So it died. RIP Keeping Crayfish in household aquariums is a hobby which I took up during the Covid19 lockdown period. Crayfish come in many colors. Here are photos of some of my Crayfish.
MY CRAYFISH LAID EGGS. (See video)
The Mother is fanning the eggs to aerate them. The eggs will take 4 to 6 weeks for the babies to hatch and they will stick to their Mother's body for 1-2 weeks. In the meantime I will have to find a way to separate the Mother and her Husband from the other crayfish. But first I have to determine which one is her Husband. The wrong choice could result in both eggs and Mother being eaten. Crayfish can be opportunistic cannibals.
Don't look at the SP500. Look at Treasuries and the USD
Chart 1: Treasuries yield rise across the board Chart 2: Normalised Principal Component Analysis loadings show Treasuries rise while USD falls Chart 3: 30 year yield minus 3 month, 1 year, 5 year and 10 year yields Most retail investors invest in the Equities market. But in this increasingly inter-connected financial markets environment, its important to look at the Bond Market and the US Dollar to understand the situation in the Equities market. The rise in the SP500 is unsustainable if bond yields rise and is even more unsustainable if...
A Comparison of Four Noise Reduction Algorithms as Applied to the BSE Sensex index.
Chart 1: Noise Reduction Algorithms Compared. Data as of 12 June 2025 As compared with established and mature stock exchanges such as the New York, Japanese and European stock exchanges, frontier and emerging stock exchanges have a higher level of ‘noise’. In financial markets, "noise" refers to the erratic and often unpredictable fluctuations in price and volume that can make it difficult to discern genuine market trends. This noise can stem from various sources, including news reports, market sentiment, and even algorithmic trading. It essentially obscures the underlying fundamental value of an asset, making it difficult for investors to make sound decision. In this post, I am applying four types of de-noising algorithms on the Bombay Stock Exchange Sensex Index (“BSE” or “Sensex”). My hypothesis is that the Sensex has a high level of noise. This is because a large proportion of the investors on the approximately 5000 stocks listed on the BSE are retail investors stee...
