A 10 gallon aquarium will hold around 200 roaches - you can order roaches and silk worms from here
www.reptilianarts.com they have good silk worms and super worms I have not ordered roaches from them my go to place is not shipping roaches at this time they are restocking and good place to get them --- I will give you the website you might want to keep it on hand -- they also have nice horn worms they ship them small and they do grow fast so order a small amount-- nice butter worms as well - the butter worms every one seems to be out at this time ---
www.dubiaroaches.com if you order silk worms from reptilian arts and you order bulk make sure you get food for them - they will come small so they will grow out you will need to feed them and clean their containers out every day -- here is another site for silk worms
www.coastilsilkworms.com they were out on the east coast but the west coast had them--
www.mulberryfarms.com they have a little of everything you can go look to see what they have --- they are on high on shipping --
www.joshsfrogs.com people on here order from there as well - I have not ordered anything from them -- the silk worms are a good staple feeder as well - so you can alternate between the dubias and silk ---
