my sea hare Slug got his head sucked into a water mover.... how I am not sure.... But I managed to gently pull him free...... he was excreeting a purple substance..... yes I got on my hands and I quickly washed it off..... my question is...... is the purple substance toxic to the reef inhabitants or the fish...... and me? he seems OK for now.. but I am sure he has a headache...... LOL......
