Saltwater Fish Spotlight: Saddle Valentini Puffer

Valentinis are a friendly puffer and reef-safe (with caution). Brightly colored with a small beak-like mouth and black "saddle" on its back. Don't be fooled by their small size, though, parts of their flesh are poisonous! They are suitable for minimum 30 gallons.

Freshwater Fish Spotlight: Peppermint Platys

Platys are hardy, peaceful, and an excellent starter fish! As livebearers, they give birth to fully formed young, as opposed to laying eggs. Peppermint Platys get their name from their stunning red and white pattern.
