Ulyunist 4-Piece Aquarium Fish Tank Cave Set - 1 Large 7.1" Tunnel + 3 Small 2.45" Hideouts | Safe Plastic Decor | Fish & Shrimp Viewing Tunnel for Corydora Catfish, Kuhli Loach(Black)

• 【Multi-Size Aquarium Hideout for Fish & Shrimp】This 4-piece aquarium cave set includes 1 large 7.1" tunnel and 3 small 2.45" round hideouts—perfect for aquarium fish (Corydora Catfish, Kuhli Loach, Pleco) and shrimp. It provides safe shelter in your fish tank, meeting aquatic pets’ instinct to hide and reducing stress.
• 【Aquarium-Safe Plastic for Durable Fish Tank Use】Made of high-quality aquarium-safe plastic, this fish tank decor is non-toxic (no harmful leaks) and scratch-resistant. It’s durable for long-term aquarium use, blending well with your tank’s substrate or plants.
• 【Flexible Combo to Customize Aquarium Layout】The set supports free combination: use the 7.1" large aquarium tunnel as a central spot, or place 2.45" small hideouts near tank plants. It fits small (10-20 gallon) to medium (20-40 gallon) fish tanks, boosting aquarium decor flexibility.
• 【Viewing Tunnel for Fun Fish Tank Observation】Unlike closed aquarium caves, this viewing tunnel lets you clearly watch fish/shrimp move through the large tunnel or dart into small hideouts. It adds interactivity to your fish tank, making daily aquarium observation more enjoyable.
• 【Easy-Setup Aquarium Accessory for Low Maintenance】No tools needed—just place the aquarium plastic tunnel/hideouts on the fish tank bottom (no burying). The smooth surface is easy to clean (wipe with a tank brush during water changes), saving time on aquarium upkeep.
