The Jewel Cichlid, hemichromis bimaculatus, is a beautiful fish that inhabits streams from southern Guinea to Central Liberia. During breeding conditions, the males have intense red colouration which is spectacular to see. These cichlids are territorial and should be housed in a spacious, well planted aquarium with abundant shelters. If there are enough shelters, these fish will be less aggressive as each of them is able to claim a certain territory within in the aquarium. Include several flat-topped rocks to mimic the cichlids natural environment. If a breeding pair is established, the female will spawn on these flat-topped rocks (flat leaves are also possible). The pair will then take turns to vigorously guard to fry. The Jewel Cichlid is omnivorous and will take dried and live foods. Keep these fish well fed or else they will become nasty fin nippers!
The Goliath Tigerfish, Hydrocynus goliath, is a ferocious predatory fish native to the Congo River Basin in Africa. It can grow up to 1.5 meters long and has be known to prey on small crocodiles and tearing large catfish into pieces! It occasionally attacks human since it is able to sense low frequency vibration in the water. It prefers to hunt in fast flowing water where smaller fish struggle to swim. Its massive teeth perfectly slide into distinct patches along its jaw. The Goliath Tigerfish is very rarely kept in any sort of aquarium although I did manage to spot a few at the Singapore River Safari the other day! See video below 🙂
The Calabar Python, Calabaria reinhardtii, is probably one of the most toughest snakes on the planet. Its skin is more than 15 times thicker than an average snake. Scientists believe that this thick layer of skin protects the snake from bites by mother rodents protecting their young. The Calabar Python preys exclusively on young rodents, hence the need to protect itself from protective mothers. Despite the thickness of the skin, it remains flexible. Pharmaceutical companies have shown interest in mimicking the qualities of the snakes skin to develop puncture-resistant medical gloves! The Calabar Python does have some limitations. It cannot swallow large prey like other snakes normally do. This partly explains their preference for small rodents. It also has a very small clutch size for a snake laying an average of 4 eggs per clutch. Other snakes normally lay up to 100 eggs per clutch 😊
