I’ve been absolutely hooked on Fish It since the Crystal Depths update dropped on January 18, 2026, and let me tell you – this underwater expansion completely changes the game! As someone who’s spent countless hours exploring every corner of Roblox’s fishing simulator, I can confidently say that Crystal Depths is the most exciting addition yet. Whether you’re a seasoned angler or just starting your fishing journey, this guide will help you unlock everything this mysterious underwater world has to offer.
The Crystal Depths is Fish It’s most ambitious update to date, introducing a completely new underwater biome accessible only through the Pirate Cove island. This expansion brings two ultra-rare Secret fish, new NPCs with rewarding quests, and an entirely new resource system centered around crystal farming. What makes Crystal Depths special is its exclusivity – you’ll need the Advanced Diving Gear (costing a whopping 1,000,000 coins) just to access this underwater paradise.
There’s something magical about diving into the Crystal Depths for the first time. The moment I equipped my Advanced Diving Gear and interacted with that mysterious boat near the Carpenter NPC, I knew I was in for something special. The atmosphere is completely different from other areas – you’re surrounded by glowing crystals, mysterious underwater caves, and fish you won’t find anywhere else. What really keeps me coming back is the thrill of hunting those Secret-rarity fish with their insane 1 in 5,000,000 and 1 in 3,500,000 catch rates!
Getting to Crystal Depths requires some preparation, but trust me – it’s worth every coin:
Pro tip: The Advanced Diving Gear is found just off the edges of the pond, so explore the area thoroughly before making your purchase.
Based on my extensive fishing sessions in Crystal Depths, here’s what you can expect to catch:
