Omothymus violaceopes
One of the largest arboreal tarantulas in the world. Females have legs that shimmer violet to blue with a grey-green carapace, while mature males turn yellowish green. It is very fast with potent venom, so it suits advanced keepers.
Omothymus violaceopes occurs in Singapore, southern Peninsular Malaysia and the Riau Islands of Indonesia, and is regarded as one of the largest arboreal tarantulas known. The legs shimmer violet to blue, the carapace is grey-green to grey-blue and the abdomen greyish blue. Males turn yellowish green at the mature moult, and the sexes can be told apart from the juvenile stage. It lives in primary lowland monsoon forest, preferring tree hollows three to four metres above the ground, though captive animals will also burrow into the substrate. Growth is fast and sexual maturity is reached at one to one and a half years. Egg sacs hold 100 to 150 eggs and hatch in about ten weeks. It is shy and nervous, but when cornered it raises its front legs in threat and will ultimately bite, which can cause severe pain, muscle cramping and nausea.

Live insects such as crickets, locusts and roaches
Keep 23-25C by day, dropping to 20-22C at night, with humidity of 60-75% and a slightly damp substrate. Keep ventilation good to prevent mould.
Being arboreal it needs an enclosure at least 40cm tall; a 30x30cm footprint is enough. Provide about 10cm of substrate plus a cork tube or a slab of bark set at an angle as a retreat.
Offer active live prey such as crickets, locusts and roaches. Its feeding response is very strong, so take particular care when feeding.
It has no urticating hairs. Normally shy and quick to retreat, it will raise its front legs in threat and bite when it has no escape. The venom is medically significant, causing severe pain and muscle cramping.
It is extremely fast and can make short leaps on its long legs, so guard against escapes during maintenance and never handle it. Wild-caught animals still reach the market, so captive-bred stock is preferable.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Singapore Blue is 23〜25℃. Recommended humidity is 60〜75%. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Singapore Blue is Up to about 14 years for females, around 5 years for males. With proper care and nutrition, they can live a long and healthy life.
