3)change in hunting behavior that replaces reliance on visual cues with reliance on tactile cues
4)change in hunting behavior that eliminates speed in favor of better camouflage,which permits an ambush strategy

Adaptations that increase the predators' speed (1), change their hunting behavior to rely less on visual cues and more on tactile cues (3), or improve their camouflage for ambush strategies (4) could all potentially help them catch faster mosquitofish. These changes would allow the predators to either match the speed of their prey, use different senses to detect them, or ambush them more effectively.
