Printed in the USA - Ships quickly from Texas

Fast U.S. Shipping + Free Returns – 100% satisfaction backed by hassle-free service.

This shirt isn’t for people who think stocking ends with a plan. It’s for keepers who’ve done the math and bought the fish anyway.

The simple tank icons and equation reflect the familiar slide from empty glass to overcrowded reality without needing explanation.

Worn at the fish store, during maintenance, or when another keeper glances once and nods.

Not made for novelty aquarium humor.

Frequently Asked Questions

What size should I order?

This is a Semi-fitted, runs slightly fitted (size up recommended) cut that runs true to size. Sizes run S-3XL; size up one for a looser fit.

What are the shirts made of?

Printed DTG on 100% ring-spun cotton (solids); cotton-poly blend (heathers). Built for detail that holds up on species-specific artwork, not a heavyweight streetwear cut.

How long until my order ships?

Every shirt is made to order in Texas after you buy. Production plus shipping runs 3-5 days. Nothing sits pre-printed in a warehouse, which is how we can carry this many species-specific designs without guessing on inventory.

What if the print or fit isn't right?

30-day returns, no argument. If the print quality is off or the size doesn't work, contact us and we'll sort it.
