The NEW Best Fish For Aquarium to make MILLIONS In FISCH Roblox: Items, XP & Money Setups

The NEW BEST FISH FOR AQUARIUM TO MAKE MILLIONS In FISCH Roblox — Build three specialized Aquarium presets: a 77‑items/hour layout using five fragments plus three relics for nonstop drops, a 20%‑of‑base‑XP lineup anchored by Elder Moss Jaw and Colossal Ethereal Dragon, and a money build tuned around 25% of each fish’s current value with Sparkling/Shiny multipliers and minimal duplicates penalties. Items profit runs at full output even offline, while XP and credits scale from in‑game formulas, so pick one goal per tank and optimize slots, food buffs, and rarity mix to hit sustainable 5–10M credits/hour rather than chasing unstable edge cases.

Items build (77 items/hour ceiling)

• Items per hour follow a rarity ladder per slot, with fragments and relics providing the highest item yields per slot when combined correctly.​​
• The best known items layout is five fragments plus three relics, which hits the widely documented cap of 77 items/hour in a single Aquarium.​​
• Fragment set: Ancient Fragment, Deep Sea Fragment, Earth Fragment, Solar Fragment, and Glacial Fragment; pair these with three relics such as Exotic, Cosmic, and Standard to finalize the 77/h template.​​
• Items/hour are not affected by the game’s offline profit toggles, so you retain full item output even when offline or AFK.​​

XP build (20% of base XP)

• Hourly XP is computed as Hourly XP=0.20×Base XP of the fishHourly XP=0.20×Base XP of the fish, so pick fish with the highest base XP rather than purely on value or rarity labels.​​
• Two top‑end XP fish highlighted are Elder Moss Jaw and Colossal Ethereal Dragon, both reported around 700,000 base XP, which converts to approximately 140,000 XP/hour per placed fish via the 20% rule.​​
• Secrets like Skyla can also serve as strong XP anchors (e.g., ~500,000 base XP yields ~100,000 XP/hour), but verify base XP in a community FishXP/Fishipedia resource before finalizing your roster.​​
• Avoid stacking duplicates of the same high‑XP fish due to diminishing returns elsewhere; build a diverse XP lineup to smooth penalties and maintain uptime.​​

Money build (25% of current value)

• Hourly credits are computed from a percentage of each fish’s current value: Hourly Credits≈0.25×Current ValueHourly Credits≈0.25×Current Value, further modified by weight, multipliers, food, and any duplicate’s penalty.​​
• The practical formula applied in meta guides includes: weight multiplier × base price per kg × combined multipliers × duplicates modifier × fish food multiplier, divided by a balancing factor, with the headline takeaway that 25% of value drives the core money output.​
• Only Sparkling and Shiny are consistently positive multipliers for Aquarium income; stacking many other mutations does not linearly improve hourly credits in the Aquarium’s calculation.​​
• Realistic, sustainable targets for top‑tier setups are in the 5–10 million credits/hour range; higher figures (e.g., ~13–15 million/hour) generally rely on event conditions, admin boosts, or edge‑case size exploits and should be considered outliers.​​

Key multipliers, penalties, and food

• Sparkling and Shiny apply a 1.5× factor to their respective attributes in the Aquarium’s money computation, making them the only consistently desirable “extra” multipliers to chase.​​
• A duplicate’s penalty applies for certain rarities (e.g., Exotic/Secret/Apex/Extinct), reducing returns if you stack the same rarity too heavily, so diversify your money lineup.​
• Fish food multipliers apply at the end of the calculation, so ensure your chosen food buff aligns with your target (money vs XP), then avoid overpaying for minimal incremental gains.​

Fragment and relic sourcing (for items builds)

• The five high‑impact fragments (Ancient, Deep Sea, Earth, Solar, Glacial) collectively drive the 77 items/hour ceiling when paired with three relics, and you can mix in relic types like Exotic/Cosmic/Standard for rounded drops.​​
• Some relics (e.g., Cosmic) are event‑gated or biome‑gated, so route time into events like Starfall and biome hunts if you’re short on guaranteed relic slots.​​

Best fish notes and tradeoffs

• For XP: Elder Moss Jaw and Colossal Ethereal Dragon sit at the top because their base XP is among the highest; diversify with high‑XP Secrets like Skyla if you lack multiple apex titans.​​
• For Money: prioritize very high base value/kg combined with legitimate size (kg), Sparkling/Shiny, and no crippling duplicate’s penalty; appraising for Big/Giant can be valuable, but the Aquarium formula does not reward every mutation equally.​
• For Items: strictly follow the five‑fragment plus three‑relic template; substitute fragments or relics only until you complete the full eight‑slot 77/h array.​​

Online vs offline behavior

• Items/hour output is identical online and offline, making the fragments‑plus‑relics template ideal for AFK or off‑session progress.​​
• Offline profit impacts money and XP only, so expect reduced returns relative to being in session, especially on aggressive money builds.​​

About extreme edge cases

• Hyper‑inflated results (e.g., ~15M/hour) often involve event boosts, admin abuse windows, or size‑reset quirks that push kg way beyond true max before settling, which is not a stable or broadly replicable baseline.​​
• While exotic bait and rod pairings (e.g., Alien mutations with certain baits) can spike value/kg, the Aquarium’s calculation still bottlenecks around the 25% value core and penalties, reinforcing realistic caps.​​

Recommended builds (quick picks)

• Items build: Ancient/Deep Sea/Earth/Solar/Glacial fragments + three relics (e.g., Exotic/Cosmic/Standard) for 77 items/hour.​​
• XP build: Elder Moss Jaw + Colossal Ethereal Dragon + 1–2 high‑XP Secrets (e.g., Skyla) to spread duplicates penalties and maximize 0.20×Base XP0.20×Base XP.​​
• Money build: High value/kg fish appraised for Big/Giant with Sparkling/Shiny, diversified rarity mix to avoid heavy duplicates penalties, and aligned fish food multiplier.​
