The Old Wife Fish is a unique addition to my saltwater tank. Its distinctive appearance and the sound it makes when caught are fascinating. I’ve kept it in a 75-gallon tank with live rock, and it’s active and healthy. The black stripes are quite striking and add visual interest.

I was drawn to this fish because of its rarity. It’s not common in most stores. After adding it to my 80-gallon tank, it settled in well. The silver body with black stripes looks great against the reef. I did have to acclimate it slowly, but it’s now a regular part of the tank.

This fish is a real standout. The two dorsal fins and the way it moves through the water are unique. I’ve kept it for over six months and it shows no signs of stress. The tank setup with live rock has helped it feel secure.
