Greenbottle Blue Tarantula Nutrition Guide: Diet & Feeding Requirements

Proper nutrition is essential for the growth, coloration, and overall health of the Greenbottle Blue Tarantula (Chromatopelma cyaneopubescens). These opportunistic predators feed on a variety of insects in the wild and adapt well to a captive diet when provided with appropriately sized, nutritious prey. This guide covers what to feed, how often, feeder preparation, supplements (if any), and hydration strategies tailored to Greenbottle Blue Tarantula.

A quick species overview relevant to feeding

• Natural diet: Mostly insects—crickets, grasshoppers, beetles, and other arthropods available in their arid scrub habitat.
• Feeding style: Active hunters and webbers that ambush prey in their webs.
• Appetite: Juveniles eat more frequently; adults feed less often but will accept larger prey.

Appropriate feeder insects

Recommended feeder types:

• Crickets (Gryllus spp.): Staple food; readily accepted and nutritious if gut-loaded.
• Dubia roaches (Blaptica dubia): Excellent staple—high in protein and low in chitin compared to some beetle larvae.
• Juvenile roaches (small nymphs) for subadults and adults.
• Small mealworms or superworms: Use sparingly—superworms can be high in fat.
• Silkworms and hornworms: Good occasional treats with high moisture content.
• Fruit flies and pinhead crickets: For spiderling and sling stages.

• Offer prey no larger than the width of the tarantula's abdomen (opisthosoma). Oversized prey can stress or injure the spider.

Feeding schedule by life stage

• Slings (very young): Feed every 3–7 days; offer appropriate tiny prey such as pinhead crickets or flightless fruit flies.
• Juveniles: Feed every 5–7 days. Growth is rapid; adjust prey size accordingly.
• Subadults: Feed every 7–10 days.
• Adults: Feed every 7–14 days depending on appetite, activity, and condition. Mature males may eat less frequently, especially after reaching maturity.

Feeder preparation and gut-loading

• Gut-loading is essential: Feed crickets and roaches nutritious diets 24–48 hours before offering them. Use commercial gut-loading mixes or fresh vegetables and high-quality commercial feeds.
• Dusting with vitamin/mineral powders is typically unnecessary and can be harmful if overused; tarantulas obtain most needed nutrients from a varied feeder array.

Supplements and calcium

• Greenbottle Blue Tarantula generally does not require calcium supplements like reptiles do. Excessive dusting of feeders with vitamin powders is discouraged.
• If you choose to supplement, do so sparingly and under the advice of an experienced invertebrate veterinarian or breeder.

Foods and items to avoid

• Wild-caught insects that may carry pesticides, parasites, or pathogens.
• Vertebrate prey (mice, small lizards): These are unnecessary, risk injury to the spider, and may introduce disease.
• Overfeeding leads to obesity-like conditions in some arachnids and poor molting; feed to maintain a healthy body condition.

Hydration and water intake

• Provide a shallow water dish at all times for adults and larger juveniles. Clean and refill daily.
• Slings may drink from tiny droplets or slightly damp substrate; use a very shallow bottle cap or similar for slings to prevent drowning.
• Greenbottle Blue Tarantula will also obtain moisture from prey; offering fresh, well-hydrated prey (gut-loaded) helps maintain hydration.

Feeding techniques and safety

• Use long forceps to present prey to avoid accidental bites to the tarantula or yourself.
• Monitor feeding events; some Greenbottle Blue Tarantula individuals may prefer to pull prey into webs and consume later—leave prey in enclosure but remove after 24–48 hours if uneaten.
• Avoid feeding wild-caught insects and quarantine new feeders when possible.

Troubleshooting feeding problems

Refusal to feed

• Often linked to pre-molt behavior—do not force-feed.
• Post-molt: wait until the new exoskeleton fully hardens before feeding (several days to a week for adults).
• Chronic refusal could indicate husbandry issues: check temperature, humidity, and overall health.

Prey too large or aggressive

• If a cricket injures the tarantula (e.g., fights back and harms legs), remove the prey immediately.
• Consider using roaches or wingless crickets for less aggressive feeding.

Overfeeding

• Signs include a bloated abdomen and lack of molts; adjust feeding frequency and portion sizes for the individual.

Special feeding notes for breeding or molting

• Mature females preparing to breed may require extra nourishment to support egg sac production.
• Do not attempt to breed unless you have experience or mentorship—breeding has specific risks, including the male’s short post-molt survival.

Sample feeding schedule (practical)

• Sling: 1–2 pinhead crickets or fruit flies every 3–7 days.
• Juvenile (1–2 inches): 2–5 small crickets or equivalent every 5–7 days.
• Subadult (2–3 inches): 3–6 medium crickets or 1–2 small roaches every 7–10 days.
• Adult (4–6 inches): 2–4 larger crickets or equivalent roaches every 7–14 days depending on appetite.

Record-keeping and monitoring

• Keep a feeding log noting prey type, size, and whether it was consumed. Track molts and correlate feeding changes with growth.
• Changes in feeding behavior can be early indicators of molt cycles or health issues.
