Not another colour form thread.
How were those spiders sexed? I know nothing of P.cancerides, but the second one just has a "male" look to me.

No offense, but its because of people breeding spiders before they know enough about it that we end up in hassles like this.
You should have first been asking these questions before mating the spiders.

Wasn't aware that the genus was so mixed up.

I found this picture of a mature male Cancerides ( green form)

Now it looks more female.

This is not directed at Jozua, but as this thread deals with something similar, I will have a quick say.

People sometimes ask why new people to the hobby shouldn't breed their spiders. Here is a clear example. If a few (Relatively well informed) people can't accurately identify a spider, how can we expect a person who has just bought their first spider to do so. The same goes for people breeding Avics. If you cannot tell with certainty of the species of an Avic, don't breed it. These accidental hybrids will be sold as pure bred spiders until one day we realise its a big mess (If that hasn't happened already)

As said before in this thread, first identify your spider and start threads like this before attempting a mating please.
