French Angelfish : Most Devoted Partners:
The French Angelfish is well known for its complete devotion to its partner. Found in the warm tropical waters of the Atlantic Ocean, these fish not just mate for life, they spend nearly every second with their spouse, traveling, hunting, sleeping and protecting their territories together. Mature French Angelfish are rarely ever seen alone and if they are, it is usually because their mate has passed away; they do not ‘remarry’ following the death of a spouse.
