Hey there everyone, I know there has always been a lot of confusion about the Grammostola Rosea and Grammostola Poteri(Chilean Rose and Flame rose hair tarantulas). So I found some nice info about them.

First up is the Grammostola Rosea (Flame rose hair chilean)(RCF)





Flame Rose Hair Chilean
Grammostola rosea

Common name: Red Rose Hair

Indigenous: Bolivia, Chile, Argentina

Habitat: The northern region is almost entirely desert and is one of the driest areas in the world. Temperatures, however, are moderated by the offshore presence of the cold Peru, or Humboldt, Current. The average temperatures at Antofagasta range from 18° to 23°C (64° to 74°F) in January and from 12° to 16°C (53° to 62°F) in July. In Santiago the average range is 12° to 29°C (54° to 85°F) in January and 3° to 15°C (38° to 58°F) in July.

Temp/humidity: 65°-78° /55%-65% humidity.

Enclosure: This is a opportunistic burrower. As a spiderling, I used a vial that would allow at least three inches (3") of substrate for burrowing. As sub-adult/adult, I use a terrarium that will allow at least four inches of substrate.

Substrate: four inches of substrate. (I use a mixture of peat moss, vermiculite, coconut fiber and dirt for firmness, as the substrate).

Retreat/Hide: This is a opportunistic burrower, therefore I Place a bark for a starter burrow hide.

Food Consumption: I fed the new born spiderlings fruit flies, then when they reached 1/2" I introduced baby crickets, My adult Red Rose Hair, I give two (2) one-inch B. dubia roaches or 5 adult crickets weekly. This specie is a so-so eater. The only time this tarantula refuses food is when it is near a molt.

Water Requirements: I keep a water dish in the tank. I have never seen mine drink. I keep the substrate in the terrarium dry.

Growth Rate: I have read that this is a slow growing specie; but with proper feeding and warmth, the growth rate of this specie is medium. I purchased this tarantula as a Juvenile.

Adult Size: They get five inches (5").

Temperament: This is a very laid back, easy to handle specie. It has never kicked hair at me nor give a threat pose. She is always out in the open and is friendly.


And then there is the Grammostola Poteri (Chilean rose)(NCF)





Grammastola Poteri
(Chilean Rose normal color phase)

Common name: Common Rose Hair

Indigenous: Chile

Habitat: The northern region is almost entirely desert and is one of the driest areas in the world. Temperatures, however, are moderated by the offshore presence of the cold Peru, or Humboldt, Current. The average temperatures at Antofagasta range from 18° to 23°C (64° to 74°F) in January and from 12° to 16°C (53° to 62°F) in July. In Santiago the average range is 12° to 29°C (54° to 85°F) in January and 3° to 15°C (38° to 58°F) in July.

Water Requirements: I keep a water dish in the tank. I have never seen mine drink. I keep the substrate in the terrarium dry.

Growth Rate: The growth rate of this specie is medium. I purchased this tarantula as a spiderling.

Adult Size: They get six inches (6").

Temperament: This is a very laid back, easy to handle specie. It has never kicked hair at me nor give a threat pose. She is always out in the open and is friendly.

Comments: This is probably now, the most common tarantula on the market. but spiderling are not that easy to come by. My first tatantula was a Rosie. I kept her for twelve years before she passed. She was an adult when I got her. I know she had to be well over twenty years old. Rosies are notorious for long extensive fasts. My girl fasted for two years on one occassion, and her abdomen never got smaller. Once a week I would throw a cricket in her cage to see if she would eat, then one day she started eating, again. I wouldn't have a collection without at least one Rosie.



All this info I got from the following website... Hope this helps everyone

Thanks Angel, I always thought I had a G rosea,:pinch: Now I see she is a G Porteri.

Saw a couple of post about this topic on different forums, but all of them
ends up with no definite answer. Some says it is the same specie and others says it 2 different species. Well your info seems the best so far.

It is still confusing in a way. The tarantulas keepers guide just speaks about 3 different color forms.

Ok to be honest you got me thinking on this one, Your post is interesting and the more I write, the more I doubt, just for example, TH got engaged yesterday, Scarab sold Metalicas and Balfouris, Zerocools wife got pregnant, and now this post.
Thanks For Posting anyway.

Well for number two, its no joke... We were busy doing our T file last night and came across this info. And I know there is alway debate on these so I though about posting it on the site.... But maybe apprantly I should have waited untill today....aka not April fools....


AND, for the first part, there are three diff ones... here is the third one





Latin Name: Paraphysa scofra

Common Name: Chilean Copper Rose

Indigenous: Argentina, Chile

Habitat: Temperate climatic conditions prevail throughout most of Argentina, except for a small tropical area in the northeast and the subtropical Chaco in the north. In Buenos Aires the average temperature range is 20° to 30°C (67° to 86°F) in January and 8° to 15°C (46° to 60°F) in July. In Mendoza, in the foothills of the Andes to the west, the average temperature range is 16° to 32°C (60° to 90°F) in January and 2° to 15°C (35° to 59°F) in July.

Temp/humidity: 76°-82° /55%-65% humidity

Enclosure: This is a opportunistic burrower. As a spiderling, I used a vial that would allow at least three inches (3") of substrate for burrowing. As subadult-adult I use a terrarium that will allow at least four inches of substrate

Substrate: four inches of substrate. (I use a mixture of peat moss, vermiculite, coconut fiber and dirt for firmness, as the substrate).

Retreat/Hide: I place a bark for a starter burrow hide.

Food Consumption: I fed the new born spiderlings fruit flies, then when they reached 1/2" I introduced baby crickets, My sub-adult Chilean Copper, I give one (1) one-inch B. dubia roaches or 4 adult crickets bi-weekly. This specie is a some what slow eater. The only time this tarantula refuses food is when it is near a molt.

Water Requirements: I keep a water dish in the tank. I have never seen mine drink. I keep the substrate in the terrarium dry.

Growth Rate: The growth rate of this specie is slow. I purchased this tarantula as a juvenile.

Adult Size: I read that they get four inches (4"). After keeping my girl for five (5) years, she has only grown to three inches plus (3+").

Temperament: This is a very laid back, easy to handle specie. It has never kicked hair at me nor give a threat pose. She is always out in the open and is friendly.

Anyone have scientific papers to back the different species up?
Is G.porteri a valid species?

this is what i found

"A publication states that G. auriostriata is a junior synonym of G. pulchripes. Basically, or overly simplified, that tarantula species was named G. pulchripes BEFORE someone came along and said it was G. auriostriata. The older name is correct.

With G. rosea and G. porteri, there are two separate species, with G. porteri NOT in the hobby, but the more colorful G. rosea (red color form?!?) incorrectly being labled as G. porteri in the hobby by some hobbyists and dealers. Until there is a publication demonstrating that in fact the hobby tarantula is two distinct species, it's all junk. Clear as cement?lol

Something similar occurred a few years ago, where a large and striped leg tarantula had been called Lasiodora cristata in the hobby, but it turned out the entire hobby had it wrong, and that spider was in fact Nhandu chromatus. Mistaken identities do occur, but there are rules. Based on those same rules, G. porteri does not exist in the US hobby. "

Thanks Angel,

I looked at these 2 lists and both appear on them.

Also looked at this thread. Shows the difference between the 2.
