i got the circle and the circle sponge and i been adding water to it and some the honey invert sugar syrup and changing it every 2 days and now there is this red spot in the sponge and another 2 what is this thanks
Could be a little mould. They are good for putting water in, but not for honey invert. It better that you give it without the sponge. But don't put to much in the circle so the ants can not drown in it.
