Marcella Butterflyfish (Prognathodes marcellae)
The Marcella Butterflyfish, also known as the Diamond Butterflyfish or French Butterflyfish, is one of the smaller and rarer butterflyfish species. It features a striking appearance with a yellow body and translucent caudal fin, while its other fins display vibrant yellow hues. Two vertical black bars run along its body, one of which passes through the eye.
It is well-suited for a Fish Only With Live Rock (FOWLR) aquarium, as it may feed on inverts and coral polyps in the vicinity. The fish can be kept singly or in pairs, but should not be housed with other species from the Prognathodes genus or similar-looking fish.
Marcella Butterflyfish prefers ample swimming space and a well-established tank environment.

The Marcella Butterflyfish is a stunning addition to my FOWLR tank. Its bright yellow body and black bars make it stand out. It’s active and curious, and it doesn’t bother the inverts or corals. I’ve kept it alone for over six months and it’s thriving.

Beautiful fish with a unique look. It’s not aggressive and spends most of its time swimming around the rockwork. I did have to make sure there were no similar-looking fish in the tank, but once I did that, it settled in well.

I was drawn to this fish because of its rarity and striking appearance. It’s active and shows off its colors well in the tank. The translucent tail is especially noticeable in the right lighting. Very satisfied with the purchase.
