L034 Medusa Pleco
Ancistrus ranunculus is a weirdly beautiful pleco from Brazil. With a highly flattened head and a face covered in ‘tentacles’, these fish are downright Lovecraftian. Care is similar to most other plecos; they do appreciate cool, well-oxygenated water. An omnivorous diet that includes meaty frozen foods should be offered.
These are stunning adults around 4″ long.

The Medusa Pleco is absolutely stunning. Its unique tentacle-like face makes it a standout in any aquarium. It’s active and peaceful, and I’ve been feeding it frozen meaty foods regularly. Water conditions are stable, and it’s adapted well to the tank environment.

First time keeping a pleco and this one is a visual highlight. The appearance is unlike any other fish. It’s not aggressive and eats well on frozen foods. I keep it in a 20-gallon tank with good water flow.

Beautiful fish with a very distinctive look. It’s easy to care for and has been thriving in my tank for over six months. I feed it a mix of frozen bloodworms and sinking pellets.
