Yeah.. alot of ppl keep the spiders in matchbox but i prefer to keep in inside the round Trebor sweet case.
Use nails to poke few holes on the top for air go in. Flip the Trebor case upsidedown and theres the fighting ring. 

I give the spider plain water, sometimes rain water or air embum early in the morning. Give them good training exercise like walking on thin string stretch far,
mirror fighting, etcs. My spiders won quite some matches in school days and some of my friends also ask me to help taking care of their spiders when its injured or kecut liao after lost in
fighting match. Just isolate the spiders for few days and keep them well.. and it will be ready for fresh matches.

Normally i only let the spider fight among same size so when lose, it just ran away. Some of the matches is very exciting where the spiders can fight few rounds solid matches
Terkam-menerkam , flip each other, break one of it arm or even fight till the death.   

Best tip for making the spider aggressive in fighting is put it facing a female spider 1st to make it "Gian" before the match with other male fighting spider. Chances to win is very high

The big ones are hard to find. It can kill other smaller fighting spider easily. Some of my friends sell those fighting spider few ringgit depends on its size and fights won.

I loves fighting spider. Their fighting skill and style is excellent

NOwdays.. hardly ppl play fighting spider liao.. but its out there always.
