I have a mature male and female tarantula. I have put a coconut shell in the female's cage. I am positive that both the male and female are mature enough to breed. The female recently shed her skin. I put them together soon after. I've been waiting a long time for babies. I removed the male after I saw them breed. It's been two months and I haven't seen an egg sac yet. The coconut shell is in their for the egg sac. They bred at night last time. Should I breed them again? I witnessed the breeding last time. What am I doing wrong?
All I know about breeding tarantulas, is you sometimes have to breed them quite a few times before they are actually bred. You will have to make sure you do this very carefully, as you probably already know; so that the female does'nt try and kill the male. Make sure the female has molted too, before you try and breed her. Be ready with a jar, in case she attacks the male. Females sometimes eat the egg sack but only if she is disturbed; so when you finally see it, make sure you put her in a quiet place, where there's no dangerof her being disturbed or she'll eat them for sure. Good luck.
What species are they? Some can make you wait several months. Some are notoriously difficult to breed. Are you sure the male is mature? Is it hooked out? Has it spun a sperm web yet? Are you sure you have a true pair? There are sites specifically for tarantula fanciers that are a great source of information.
If you have a species suffering habitat loss and danger of extinction it is common practice to breed the male and then send him out to other hobbyists with mature females on breeding loans because once the male matures his life is nearly at an end. If the female is gravid (pregnant) now putting the male back in will certainly cause his death and may upset the female.
