Normally I would keep in match boxes, old casstle tape &
those sour plum container.
Feeding wise would be ants, flying ants, mosquito and all sorts
of small insects.
There are many types of colour ranging from light blue, white,
silver, gold & black
I still miss one of mine which was eaten by ants...I train it
from blue until it completely change to pure black. And it was
always fierce in battle, when they start to stare at each another.
My blackie would jump from long distant and bit off the opponent
arms..
Still miss the old days...
