Your question looks like it’s asking about a specific Robux amount connected to “u lemon fisch” in Roblox Fisch—but based on publicly available info, there’s no single well-known figure or official source that says “U Lemon Fisch was X Robux.” Instead, here’s what the community and wikis do document around lemon-related items, mutations, and gamepasses in Fisch:

What “Lemon” Means in Fisch

  • Lemon is a mutation , not a fish species. It multiplies a fish’s sell value by up to 6.5× and turns it yellow with white accents.
  • Players chase Lemon mutation for profit and quest progress (e.g., Lemon Rocks quest).

How Players Get Lemon (Not Directly “Robux”, but In-Game Path)

  • The main method is using the Lemonade Serenade rod , which gives a 20% chance to apply Lemon mutation when you catch a fish.
  • To obtain Lemonade Serenade:
    1. Complete Captain Kong’s quest line.
    2. Collect 20 Lagoon Lemonades.
    3. Buy the rod from the Sunshell merchant.

This is all in-game grinding and questing—not a direct Robux purchase.

Robux-Related Items in Fisch (Context)

While Lemon itself isn’t a Robux item, Fisch does have many gamepasses and cosmetics you can buy for Robux, such as:

  • Gamepasses like universal unfavorite sell (399 Robux, discounted to 320).
  • Cosmetic boat/skin bundles, bobbers, and rods in the Animal Update and other seasons (examples: 79–2,499 Robux depending on item).

These can help you fish faster or look cooler, but again: the Lemon mutation is obtained via gameplay, not a fixed Robux price tag.

Why “how much robux was u lemon fisch” Is Unclear

  • There’s no canonical “U Lemon Fisch” item with a listed Robux price in official wikis or major guides.
  • The phrasing likely comes from forum/TikTok/YouTube chatter (“trading u lemon LF boat/skin”) where “u lemon” means “your Lemon(-mutated) fish/boat/skin,” not a store item.

Bottom Line

  • Lemon mutation = in-game effect (up to 6.5× value), obtained via Lemonade Serenade rod and quests.
  • No verified Robux price exists for “U Lemon Fisch” as a standalone purchasable item.
  • Robux in Fisch is mostly for gamepasses, cosmetics, and convenience boosts , not for directly buying the Lemon mutation.

If you meant a specific trade you saw (like “I gave X Robux for a Lemon fish/boat”), that value would be player-to-player and not an official price—so it varies by server, rarity, and negotiation. TL;DR: There’s no official “U Lemon Fisch = X Robux” figure. Lemon is a mutation you get by questing and using the Lemonade Serenade rod, while Robux in Fisch buys gamepasses/cosmetics, not the mutation itself.
