Product description

Melopoeus minax (Thai Black Earth Tiger Tarantula) The Thai Earth Tiger is one of the largest Earth Tigers in the hobby, and the nickname "Big Black" tells you everything you need to know. This heavily built fossorial species out of Thailand features a deep, rich jet-black body with warm gold banding at the leg joints and subtle dark striping across the abdomen. Not flashy — just bold, dark, and imposing. Adults carry serious mass and presence, and a full-grown specimen at the burrow entrance is one of the more striking sights in an Old World collection. A true burrower with a heavy webbing habit and lightning-fast defensive response, this is a hands-off display species for experienced keepers who appreciate natural behavior over interaction. Recently reclassified from Cyriopagopus to Melopoeus per the 2026 World Spider Catalog revision.

Coloration: Deep jet-black body with warm gold banding at the leg joints and subtle dark abdominal striping. Simple, bold, and striking in person. Adult Size: One of the larger Earth Tigers in the hobby, reaching 6 inches and beyond. The "Big Black" nickname is earned — this is a genuinely large, heavy-bodied animal. Heavy Webber: This species webs its burrow entrance extensively, creating visible tunnel structures that make for an active, interesting display even when the spider stays out of sight. Feeding Response: A reliable nocturnal ambush predator. Takes prey confidently at the burrow entrance and is one of the more consistently feeding Earth Tigers when properly established. Fossorial Behavior: A true deep burrower that will excavate serious tunnel systems given sufficient substrate depth. Set it up right and watch it do exactly what it would do in the forests of Thailand. How should Melopoeus minax "Big Black" be kept? Adult Size: Reaches 6 inches and beyond. One of the largest Earth Tigers available in the hobby, with the heavy build and mass to match the name. Enclosure: Fossorial setup with 2 times the leg span as footprint and 3 times as height, with substrate depth 2 to 3 times the leg span to support deep stable burrows. Given the adult size, this means a serious depth of substrate. A secure lid is non-negotiable. Temperature: 75 to 80 degrees F. Stable room temperature works for most keepers. Avoid sustained temperatures above 85 degrees F. Humidity: Moderate to high. Keep lower layers of substrate slightly damp while allowing the top to dry. Never swampy. The moisture gradient gives them the microclimate choice they rely on in the wild. Water: Provide a water dish near the burrow entrance. Fossorial species benefit from ambient moisture and will use a dish placed at substrate level. Diet: Crickets, roaches, and other feeders sized appropriately to the carapace (head). Feed weekly for spiderlings, every 7 to 10 days for adults. A large adult can take substantial prey. Temperament: Very defensive, fast, and prone to bolting. Best suited for experienced keepers. This is a display and observe species. Are there any additional notes or considerations? Substrate depth matters: Needs depth of soil and good airflow to get fresh air into burrows and prevent mold growth. Given the adult size, plan for 8 to 12 inches of packable moisture-retaining substrate. Settling in: True burrowers will dig straight down given sufficient depth. A starter burrow against the enclosure wall helps them establish faster. Visibility: Less disturbance equals more surface visibility. Most specimens will be seen at the burrow entrance regularly once they feel secure. Taxonomy note: This species has gone through three genus changes recently — it was widley known under Haplopelma, moved to Cyriopagopus, and now reclassified to Melopoeus per the 2026 World Spider Catalog revision. Same animal, updated science. Captive bred: Our animals are 100% captive bred. Listing Notes This listing includes multiple size options. Animals are unsexed, there is approximately a 5050 chance of male or female on most species.
