My Mutual had to find a home for two tarantulas, female Chilean rose and male Brazilian salmon pink birdeater. I've offered to take them in due to the neglect they were getting else where. I've asked about how long they've been in the environment and how old they are, which I have no answer to. The Chilean rose looks fully grown and the LP looks tiny and slim. I'm really worried about both. The vivariums I was given are barely filled an inch of soil/ bark, they both have been barely fed or even given water. They both currently have shallow water bowls and only the LP has a hide. Im planning on purchasing better vivariums and a hide for the Chilean rose, additionally a better and much deeper soil. I've never owned a tarantula before, any tips would be helpful. I will also buy food, planning on buying locust and mealworms.
