Grammostola actaeon (Brazilian Wooly Black)

Think of the Grammostola actaeon as the "Brazilian Black's" bigger, flashier cousin. While the famous G. pulchra is all black, the actaeon (often called the Brazilian Wooly Black or Brazilian Red Rump) features that same jet-black, velvety sheen but adds vibrant red setae on the abdomen. They are incredibly bulky, heavy-bodied tarantulas that command attention. They are generally calm, hardy, and long-lived, making them a "holy grail" species for many Grammostola collectors who want something rarer and slightly more colorful than the standard black tarantula.

*This is one of my favorite Grammostola species.  Impressive species, and I do believe they are the "flashier" version of the Pulchra (brazilian black).  Although, not has heavy bodied compared to the pulchra.  I have a few specimens left, and they are all very docile, and chill tarantulas.  Have handled them quite a few times, so they are tolerant to handling.

📢 Special Notices & Resources

Growth Note: Like most in its genus, the actaeon is not a speed demon when it comes to growth, but they tend to grow slightly faster than the G. pulchra or rosea. Patience is key, but the end result is a massive, stunning display animal.

💡 Care Details
🌡️ Temperature 75–85°F (24–29°C). They are very comfortable at standard room temperatures, but keeping them on the warmer side (closer to 80°F) helps improve their metabolism and growth rate.
💧 Humidity 65–75%. I keep a water dish available at all times and overflow it occasionally to dampen a corner of the substrate. The rest of the enclosure can remain relatively dry.
🏠 Housing
Babies (Slings) 1–4 oz deli cup with needle ventilation.
(FREE container available at checkout IF requested).
Juveniles Enclosure 2–3× body size. A simple acrylic box or Kritter Keeper is perfect. Provide a hide, as they can be shy when young.
Adults Standard terrestrial enclosure (5–10 gallon). They get large and bulky, so floor space is important.
🍽️ General Diet
Crickets + roaches (Dubia, Red Runner, Lobster, Madagascar Hissing). For babies, I use baby crickets or baby roaches. If the prey is too big, I pre-kill it (crush the head) and leave it; I always remove leftovers or the bolus the next day. Occasional treats for super large specimens can include a pinky/hopper mouse or feeder lizard, but very sparingly (excess calcium can cause constipation). We never use pinhead crickets because they do not provide enough protein.

⚠️ Safety Disclaimer

Safety Disclaimer: Experiencing a tarantula bite is an extremely rare occurrence, and it's important to note that there have been NO recorded fatalities due to a tarantula bite. The venom potency varies across species, with Old World tarantulas generally having stronger venom than their New World counterparts. Within the Old World category, the Poecilotheria genus is known for having particularly potent venom.

It's crucial to approach tarantulas with respect and understanding. If you happen to get bitten, which is unlikely, the key is to stay calm. In most cases, the discomfort is superficial and subsides within a few minutes to a few hours. However, bites from species with more potent venom may result in symptoms lasting up to a week. Remember, larger tarantulas tend to have more venom than smaller ones.

Please be aware that I cannot assume responsibility for bites. Tarantula handling should be done at your own risk. In my 13 years of experience with these creatures, I have only been bitten once, by a species with highly potent venom. While the experience was painful, the symptoms had completely disappeared after a week.

Handle tarantulas responsibly, and always prioritize your safety and the well-being of the tarantula.
