Ok, a little background info: I help take care of several animals that belong to my uni. There are also several other people that care of these animals throughout the week. Recently, we acquired an A. Metalica (pink-toed tarantula).
One guy told everyone that there should always be live prey in the enclosure, but the tarantula eats them right away, so people have been feeding her 1 to 2 cockroaches EVERYDAY (monday-friday). Call me crazy, but doesn't that sound like a little too much?
Also, I'm pretty sure that she's not an adult yet, and she just molted about a month ago, if that helps.
