💙FREE TO A GOOD HOME! 💙

🐟 MEET QT (CUTIE)! 🐟

Cute name, BIG appetite, and a splash of personality! Meet QT, our fully grown saltwater Pinfish (Lagodon rhomboides) looking for a forever home! 🏡

Some things to know about QT:

Gender: A mystery! 🤫

Personality: Mesopredator, and grazer

Diet: Opportunistic eater who loves crabs, snails, and other invertebrates! 🦀🐌

🏡 QT’s Dream Home:

✅ 90-gallon MINIMUM, QT has to have room to roam!
✅ FISH-ONLY saltwater aquarium — inverts are snacks, not roommates! ❌
✅ Similar size fish have to be in the tank with QT, no little guys!

🤯 FUN FACTS!

🌎 Pinfish are found in 24 locations throughout the U.S.!
🎨 QT is a real-life mood ring! Pinfish can rapidly change color based on mood or temperature!

QT is ready to swim into someone’s heart (and 90+ gallon tank)!
