feeding

How often and how much should i feed my tarantula? I just fed her 2 medium to large crickets.

Depending on the size of the crickets our rosehairs will gobble up 3-5 a week. Remove any uneaten ones after they've had their fill - you don't want to leave them in there extended periods of time.

so should i feed him 2 crickets every 3 days?

I would stick to a weekly schedule and try 3+ as weekly is a lot easier to maintain in the long run.

I would also recommend you stick to a weekly schedule. If it starts refusing, it's either full or it's going into premolt. It may be in premolt for months and still refuse food. When that happens, I'd offer it food once a month or so, but take the uneaten feeders out right away. The T will be fine as long as the abdomen isn't shrinking.
