yellow vs brown confrontation between two different slime molds

[Cyrill Fromm]

My brown slime mold and my Physarum polycephalum encountering each other. At fist it seemed like the faster P. polycephalum tried to attack the other slime mold but they dont really harm each other, they only competete for food. Sometimes they overgrow each other and seem to move as one, two colored plasmodium
