After Dark: Goth Medaka Shirts
A goth-inspired collection, here all year: medaka shirts with Victorian moths, crescent moons, fireflies, a stained glass window, and rice fish swimming in the glow. Every design comes as a tee, a long sleeve, and a crewneck sweatshirt in the dark colors, printed to order, one price in every size. A gothic fish shirt for the keeper who checks the tubs by flashlight, and an easy aquarium gift for anyone who loves the night. See every After Dark style.
Fish Keeper Shirts
My hand-drawn medaka, a few honest slogans, and two field guide plates. Most designs come as a tee, a long sleeve, and a crewneck sweatshirt: pick the design, then the style on its page. One price in every size.
Firefly Medaka Logo Gear
The Firefly Medaka fish on a garment-dyed tee, a Softstyle tee, an embroidered hoodie, and a Heavy Blend crewneck, for cold mornings at the tubs and everything in between. One price in every size, up to 5XL on the Softstyle tee and the fleece.
Fish Keeper Hats
Caps, truckers, and dad hats with the Firefly Medaka fish on the front, most of them embroidered in real thread. Built for sun, pond work, and the fish store run.
Home and Gifts for Fish Keepers
A mug for the morning tank check, a sheet of nine medaka stickers in their strain colors, a kiss-cut vinyl decal in the shape of the fish, a double-sided garden banner for the patio tubs, and a two-sided ceramic medaka ornament with no year on it, so it comes back out every December.

Medaka goods for rice fish keepers
Everything here carries the Firefly Medaka fish, a quiet nod that fellow rice fish keepers will recognize and a small mystery for everyone else, and everything earns its keep: caps with the fish embroidered in real thread, vinyl decals that shrug off water and sun, and soft-washed tees, long sleeves, and sweatshirts for everything in between. Quality blanks, premium finishes, no throwaway items. Every design is printed from my high-quality, perfected vector logo artwork, so the fish stays crisp on everything from a small sticker to a 2XL tee.
Goth fish shirts, all year
The After Dark collection is my darker side of the shop, and it stays in the shop all year: the Firefly Medaka fish with night moths, crescent moons, and fireflies, drawn in bone and Firefly pink for black and Berry shirts. Every medaka in the art follows the real fish, from the short dorsal fin set far back to the big eye, so it reads as a rice fish to anyone who keeps them. It is a goth fish shirt for Halloween or any night of the year. Looking for a present? My guide to gifts for fish lovers covers the rest.
Wear the hobby
Every purchase helps support a small medaka farm in North Carolina. Merch is a non-live item, so it ships on its own for a flat $4.99 on its own schedule rather than waiting for my Monday shipping day, order any time, with or without fish. See my shipping details for delivery info.
