Chaco GBB Breeding

So, I just received my mature pair of GBB and a MM Chaco. I've only ever bred Versi's and I'm still waiting on an egg sack, over a month later now.
I've heard I should shark tank the Chaco. Should I do the same with the GBB?

If anyone has any tips on being both of these species I would greatly appreciate it! I would also appreciate any links to any websites I could reference.

Thank you all in advance!!!

The breeding reports have some good info on both species.

Where do I find them at? I use taptalk to navigate ab and I couldn't find it.

Do these links work? The threads are in Reports under the Classifieds section.

C. cyaneopubescens thread.

G. pulchripes thread.

Waiting for a sac is a long vigil. They usually start egg production after mating. I don't think I've ever gotten a sac within a month or two of mating.
