What is the Aquarium trend?
The Aquarium trend is an AI video format that takes a still photo and renders the subject as if submerged in a giant aquarium: water rises around them, fish drift past, and bubbles float upward through soft blue light. The finished clip looks like a dream sequence — calm, slow, and a little surreal — which is exactly why it stands out in feeds full of fast dance clips.
The trend runs on Higgsfield’s Aquarium featured effect. Higgsfield’s own effect page calls it a “Kling AI Video Effect” and describes the result this way: “The subject appears submerged in a vast aquatic world, surrounded by shimmering fish and drifting bubbles. Calm, surreal, and dreamlike.” The effect sits in Higgsfield’s official viral effects gallery alongside the other trends we cover on our AI Video Trends hub.
It has real audience proof beyond Higgsfield’s own gallery. A YouTube tutorial on making viral underwater videos with Higgsfield has passed 86,000 views, and smaller creator Shorts show the same Aquarium transition built with Higgsfield, including versions paired with Kling. That combination — an official effect page plus independent creator videos — is what earned this trend a post under our two-source rule.
How to make the Aquarium video in Higgsfield
The basic version needs no prompt writing: the Aquarium effect builds the water, fish, and bubbles from your photo. If the generation screen shows a prompt box, the exact text below keeps the result on-style. The steps after it cover the full workflow with the cost of each step.
The exact prompt to use
The Aquarium featured effect generates from your uploaded photo — the motion is pre-built, so the page does not ask you to describe water or fish. Paste this into the prompt box only if the generation screen shows one:
Underwater dream sequence: the person in this photo is gently submerged in a vast blue aquatic world, shimmering fish drift past in the background, bubbles rise slowly around them, soft light rays filter down through the water, calm surreal cinematic mood, smooth slow motion, photorealistic detail, 5 seconds
Keep the prompt short. The effect already knows the Aquarium look — the prompt only steers the mood, not the mechanics.
Step-by-step instructions
1. Pick a bright photo of yourself. A well-lit portrait or selfie with a plain background works best — the effect needs clear facial detail to keep you recognizable underwater. Use a photo you took or one you are licensed to use — never upload someone else’s photo without their permission. Cost: free with your own photo; generating a base portrait with Soul 2.0 costs 0.12 credits.
2. Open higgsfield.ai, head to the Viral or Effects gallery, and pick ‘Aquarium.’ Cost: free to browse; you need a Higgsfield account. The Free plan is $0 with 0 credits (checked 5 Nov 2026), and most video models are marked ‘Not included’ on it.
3. Upload the photo and press Generate. Cost: one featured-effect generation — featured effects such as Floating Fall run about 84 credits (checked 5 Nov 2026; confirm the figure on the effect page before you generate).
4. Watch the result and re-roll if the water looks pasted on or your face warps. Cost: every regeneration spends the same credits again, so budget for 1–2 retries on top of the first generation.
5. Download the clip and post it. Cost: free — trimming in your phone’s editor or inside TikTok and Instagram costs nothing.
6. Optional: add a caption or a voiceover. Cost: captioning is free; an ElevenLabs voiceover runs about 450 characters for 30 seconds of narration at 1 credit per character, so a 30-second voiceover costs about 450 credits.
What the Aquarium trend costs
A single finished Aquarium clip usually costs one featured-effect generation plus one retry — roughly 168 credits if both generations land at the featured-effect rate. On the Starter plan’s 270 monthly credits, that is about one finished clip per month after retries; Plus (1,200 credits) and Ultra (3,000 credits) give far more room to experiment.
| STEP | ACTION | CREDIT COST |
|---|---|---|
| 1 | Aquarium-ready photo (your own or Soul 2.0) | Free or 0.12 |
| 2 | Open the effect page | Free |
| 3 | First generation | About 84 (confirm on page) |
| 4 | Retry | About 84 each |
| 5 | Download and post | Free |
| 6 | ElevenLabs voiceover (optional) | About 450 characters = 450 credits |
Pros and cons
The Aquarium trend turns an ordinary selfie into a calm, shareable underwater clip in minutes, but the water effect has clear weak points. Here is the honest split.
Pros
• Needs only one photo — a bright selfie you already have is enough to start.
• The effect builds all the water motion itself: rising water, drifting fish, bubbles, and light rays, with no prompt engineering.
• The calm, dreamlike mood stands out in feeds crowded with loud, fast clips.
• Fast to make: upload, generate, post, usually inside ten minutes.
• No filming gear needed — no waterproof case, no pool, no location scouting.
Cons
• One generation costs featured-effect credits (about 84), far more than a Kling 3.0 clip at about 7 credits per 5 seconds.
• Faces can blur or warp as the water effect washes across them.
• Fish and bubbles can look pasted-on when the photo’s lighting clashes with the underwater scene.
• Clips run only a few seconds, so the format repeats fast for viewers who have seen several.
• Every retry spends the same credits again, so a weak first photo gets expensive.
Who should NOT use it
Do not use the Aquarium trend on a real person’s photo without their clear permission — generating a video of a real person who did not agree to it is a real-person deepfake, and this site does not cover that. The same rule covers copyrighted characters: do not upload a cartoon, anime, game, or movie character and animate it as if it were your own footage. Use only photos of yourself or images you are licensed to use.
Also skip the trend if your photo is dark, blurry, or heavily filtered — the underwater effect needs clean detail to anchor the water and light. And if you want a long narrative video rather than a looping few-second mood clip, a text-to-video model such as Kling 3.0 gives you more control per credit than a one-shot effect. For a louder, party-style alternative, our Money Rain Trend guide covers the cash-fall effect in the same step-by-step format.
Frequently asked questions
What is the Aquarium trend?
The Aquarium trend is an AI video that submerges the person in a photo underwater, surrounded by fish and rising bubbles. It runs on Higgsfield’s Aquarium featured effect, which the official effect page describes as a Kling AI video effect where ‘the subject appears submerged in a vast aquatic world.’ The result is a calm, surreal few-second clip made for TikTok, Reels, and Shorts.
How much does the Aquarium effect cost in credits?
One Aquarium generation costs about 84 credits, the featured-effect rate our hub lists for effects such as Floating Fall (confirm the figure on the effect page). A finished clip with one retry therefore runs about 168 credits. On the Starter plan’s 270 monthly credits that is roughly one finished clip per month; Plus and Ultra allow far more retries and experiments.
Can I make an Aquarium video for free?
No. The Free plan ($0 with 0 credits, checked 5 Nov 2026) marks most video models as ‘Not included,’ so the effect will not generate on it. The cheapest path is the Starter plan at $19/mo (checked 5 Nov 2026). Browsing the effect gallery and uploading a photo cost nothing — only the generation spends credits.
What photo should I upload for the Aquarium trend?
Use a bright, sharp photo of yourself with your face clearly visible and a plain background. Good lighting matters more than a fancy camera: the effect matches underwater light to your photo, so dark or grainy shots produce muddy results. Waist-up or portrait framing works better than full-body shots, which shrink your face in the frame.
Can I use someone else’s photo in an Aquarium video?
No — not without their clear permission. Generating a video of a real person who did not agree to it is a real-person deepfake, and this site does not cover that practice. The same applies to copyrighted characters from cartoons, anime, games, or films. Use only photos of yourself or images you hold a license for.
Why does my Aquarium video look fake?
The usual causes are a dark or low-resolution source photo, which makes the water and light look pasted on, and face warping where the effect bends features during the submersion. Re-roll with a brighter, sharper photo; two or three retries from a clean source usually beat ten retries from a weak one. If faces keep warping, change the photo instead of burning more credits.
