I got the circus ant farm as well.
Got it last year, hoping to have connected to my original ant farm.

Coco peat does not work as nice as sand, and when packing it into the unit it kinda pushes the unit apart. you have to compact the palm peat or it looks cr8p .
the ants also do not make nice tunnels through it,
Sand works much better.

The ants I had in the unit wore great lots fun to see them hard at work, after a month I noticed that the colony was not eating the food left for them in the food chamber, on looking closure the ants wore getting through holes onto of the unit and getting there own food.

Answer is simple.
Frog will eat small T's, T's won't eat small toxic frog.
T has to be at least bigger than the frog in my oppinion.

So your main test is to see if they can both live together.

I'm not so sure the spider will know if the frog is toxic or not.
They are not that smart. but interesting none the less to see what out come, comes from your test!

Do you have a date, that you would like to set the whole thing up and get it started.
