Aquarium Knife

Aquarium Knife Overview

About Aquarium Knife

Aquarium is a legendary knife added during the Summer Event 2025. It was unboxed from the 2025 Summer Box, which cost 800 Beach Balls or 1 Summer Key to open, and it had a 5% chance of dropping. The Summer Event 2025 ended on October 18, 2025, so the box is closed, and trading is now the only way to get Aquarium.

Appearance and Best Pairings

Aquarium is a blade painted with an underwater coral reef scene, with clownfish, yellow tangs, and corals in orange, yellow, green, and pink on a deep blue background. The guard is dark red, and the handle carries the reef colors on a darker base. The Aquarium Knife belongs to the Aquarium Set, and its Set partner is the Aquarium Gun, a blue revolver with fish across the barrel and grip.

Aquarium Knife Background

Two items in MM2 are named Aquarium: this 2025 knife and the Aquarium Gun (2025), a legendary gun. Both come from Summer Event 2025, but they were obtained differently, so check the type before accepting a trade. The knife was the legendary pull in the 2025 Summer Box. Here is where it sat among the other items in the box:

• Striped Knife, Stickers Gun (Summer 2025), Dolphins and Skyline (common): 70% each

• Soda Knife, Retro and Lava Gun (uncommon): 15% each

• Neon Gun (2025) and Pop Art Gun (rare): 10% each

• Aquarium (legendary): 5%

• Sunrise and Chroma Sunrise (godly): 0.2% each

At 5%, Aquarium was the rarest item in the box below the two godlies. It was the only crate in the event, so anyone wanting the knife had to open it.
