Rescue Story

Otto's 6-Month
Transformation

Otto arrived in a 10-gallon tank at 11 inches — already stunted, already stressed. He'd been there two years. His lateral line was damaged, his fins were frayed, and he circled constantly.

Six months in our 120-gallon rehab tank: clean water, correct temperature, proper filtration, enrichment. He stopped circling on week three. His colors came back on week eight. He started watching us walk past on week twelve.

Otto is now available for adoption to a home with 75+ gallon setup and cichlid experience.

I came to Fin looking for a rescue betta. I left with Gerald and a 20-gallon planted tank I'd been putting off building for three years. He made me a better hobbyist.

How it works

From Scroll to Splash

Adoption is straightforward. We just need to know the fish is going somewhere good.

Step 01

Browse the Fish Room

Scroll through our current residents. Each card tells you species, temperament, minimum tank size, and the short story of how they arrived.

Step 02

Apply to Adopt

Tell us your tank size in gallons, your current inhabitants, and share a photo of your setup. We need to know the nitrogen cycle is handled.

Step 03

Get Approved

Our volunteers review within 48 hours. We may ask a few follow-up questions. We're not gatekeepers — we just want the fish to thrive.

Step 04

Welcome Home

Pickup is at our foster network. We'll send you a care sheet specific to your fish and check in at 30 days. You're not alone.

Surrender a Fish

Can't Keep Them?
We Get It.

Life changes. Moves happen. Allergies appear. Tanks get too demanding. Surrendering your fish to Fin isn't giving up — it's making sure they end up with someone ready.

We accept bettas, cichlids, community fish, plecos, loaches, and most freshwater species. We cannot currently accept goldfish, koi, or marine fish.

We respond within 24 hours

We never charge surrender fees. This is a rescue, not a business.
