Ride A Fish Fish Speed: What Makes a Fish Faster

Ride A Fish states exactly two things that make a fish faster: hatching rarer fish, and the rain mutation the game says can strike your fish and turn them faster. Everything beyond that — species speed charts, confirmed mutation multipliers, "fastest fish" rankings — is not verified, and this page keeps that line visible. Speed matters most on egg runs, because a carried egg breaks if you leave it too long. Here is what the game itself promises, what players have recorded, and how to compare your own fish fairly when you need the quickest ride home.

What the game officially says about faster fish

The official experience description for Ride A Fish by Dream TW Games names exactly two influences on ride movement:

• Progression: "Hatch Rarer & Faster Fish to Find Rarer Eggs" — rarer fish are framed as faster fish, and they are the intended tool for hauling back rarer eggs.
• Weather: "The rain can strike your fish, causing them to mutate and become faster."

That is the complete official list. The same description names no fish species, no speed numbers, and no mutation multiplier. In practice the loop looks like this: dive for eggs, hatch them, then ride your new fish out to reach rarer eggs before the carry timer kills them — which is why speed pays off on every run. For pushing your hatches up the rarity ladder, see how to get rare fish.

The speed number on a fish is not a species stat

Fish do carry a speed readout, and players check it right after hatching. One streamer dismissed a new fish at 200 speed as "so slow," praised a 3,900 fish as fast, and later called a 190,000 fish "fast, but not that different"; another session's best fish sat at just 566. These labels are real and worth a glance, but they describe the individual fish in front of you — not its species.

Two reasons you cannot build a ranking from them:

1. The scale is not consistent across sessions. In one video, a fish labelled around 190 seemingly outswam one labelled 95,000.
2. No source supplies a species-by-species dataset. All twelve confirmed fish, from Milkfish through Flying Fish, remain unranked for riding speed, and the official description contains no speeds at all.

So there is currently no verified fastest fish, no per-species speed chart, and no basis for claims like "the 95,000 fish is fastest." That rarer fish ride faster is the game's stated direction and a common player impression — one rider felt his pipefish beat his milkfish and guessed rarity drives speed — but one session's impression is not a measured rule. For the confirmed names, see the fish list.

Rain, lightning and mutations

The weather line is official but thin. In the only reviewed rain event, the strike visibly mutated a carried Coral Egg — a notification named the egg and the basket gained a Rays label showing Mut[RAYS] x1.5 — not the fish being ridden. That x1.5 tag never says what it multiplies, so it cannot be promised as "50% faster movement," and a lightning flash alone does not prove your fish mutated: read which object the message names. There is also no known way to summon rain or force a strike. The lightning mutation guide walks through that event in detail.

Separately, one player reported fish mutations named Bubble, Thunder and Bolt that raise both money and speed, with Bolt the best — single-session commentary with no controlled measurement. A companion description tells players to chase Gold, Diamond & Rainbow mutations, so mutation hunting is clearly an intended feature even though no speed values are documented for it. And in one recording, a lightning strike produced no visible speed benefit at all. Treat "mutations make you faster" as an official claim you can admire in the sky but not currently plan around.

Feeding and other reported influences

Two recordings associate feeding with a rising speed readout. One player fed a manta ray and watched its displayed speed climb from 125 to 251 and later 436, confirming in chat that feeding raised it; another credited a Kraken reaching 1,000,000 speed to the food it was given. These are single-session observations of individual fish with no controlled test, and the guides that document feeding treat it as growth/EXP-oriented — so do not assume feeding always makes a fish faster. What feeding does on the record is covered in how to feed fish. The same session also guessed that bumping into things lowers speed temporarily before it recovers; again, one unverified impression. If feeding does move the number, it is a possible bonus on top of the two official influences, not a replacement for them.

How to compare your own fish fairly

Because no shared speed scale exists, the only trustworthy comparison is one you time yourself. Keep everything identical except the fish:

1. Fix a circuit. Same start, midpoint and finish for both rides; pick a route you can repeat without hunting for landmarks.
2. Time the baseline. Ride your current fish and record the seconds from the same start action to the same finishing landmark. Note the fish, weather, carried egg state and any interruptions.
3. Swap only the fish. Unequip the current fish in the aquarium and bring out the challenger — the equip sequence is in how to equip fish. Confirm which fish is mounted before starting, and leave the route and timing rule untouched.
4. Compare reproducible runs. Repeat the run and keep collisions, detours and disconnects out of the comparison. Prefer a result you can reproduce over one lucky attempt.

Read the result as route time, not an internal speed stat: time reduction = (baseline − new) ÷ baseline × 100, using your own runs. If weather, a mutation label, the route or the carried egg changed between runs, record it — a faster-looking animation, a heavier fish or a rarer label alone does not prove a faster ride. Change one thing at a time; swapping fish and route together tells you nothing. Use the fish that wins reproducibly, keep the known baseline if results are inconsistent, and keep the conclusion tied to the fish you tested — one good run is not a species tier.

Aquarium numbers that say nothing about speed

The aquarium and Index panels show plenty of impressive numbers. None of them is a movement stat:

When in doubt, ignore the panel and run the route test above. The panel's own mechanics are covered on the fish stats page.

Bottom line

Ride the rarest fish you have hatched — that is the game's own rarer-and-faster direction — and keep an eye on the sky during egg runs, since a rain mutation is the one speed boost the developers have put in writing. When two fish feel close, time them on the same circuit instead of trusting the labels, and ignore any leaderboard until real measured data exists. For the weather effect itself, read the lightning mutation guide; for every confirmed fish name, see the fish list.
