Order by Friday — fish & shrimp ship Monday, $20 flat by USPS Priority Mail, with tracking emailed on ship day. Small non-fish orders ship for $7. We'll confirm your ship date by email the next day.
Live Arrival Guarantee: If there’s any issue with your shipment, let us know right away with details and photos so we can make it right. Please report dead-on-arrival fish within 1 hour of delivery for a refund or replacement. While losses are rare, we’ve got you covered when they happen.
We hold shipments when the route isn't safe: if route temperatures, other conditions, or delays put your fish at risk, we will hold the order, notify you immediately, and ship as soon as conditions are safe. Is it safe to ship your order now? How we decide →

Our Pure Strain N Class Endlers Livebearers are guaranteed to arrive alive and healthy when you are present to receive the package on the first delivery attempt.
Dead-on-arrival (DOA) incidents are rare due to the hardy nature of Endlers; however, if a DOA occurs, please email The Endler Shop within one hour of delivery with clear digital photos. Once verified, a refund for losses will be issued or replacements shipped. Photo guidelines will be included in the shipping and tracking notification sent when your order ships.
Healthy Young Adults Ready to Thrive
We typically ship robust, young adult fish, which are well suited for safe transport. At this stage, both males and females are at or near breeding age and the males are showing color and pattern. Females are selected by age and are typically non-gravid. Visibly gravid females are generally within 1-2 weeks of dropping fry.
The healthy and safe arrival of your Endlers are our top priorities. Endler orders are carefully prepared and sent via Priority Mail expedited shipping. Packages typically ship the week following purchase as fish preperation takes a few days. We ship on Mondays so fish never sit in a facility over the weekend. Because live animals require special care, these shipments are temperature and weather dependent and may be delayed until conditions improve along the entire shipping route. You’ll receive email updates with a scheduled ship date a day after your order is placed, tracking details on ship day and delay notifications when it's unsafe to ship, so you always know what to expect.
Every order is packed with care and backed by our Live Arrival Guarantee
Secure, insulated packaging and temperature-control packs as needed.

Order Cancellations & Processing Fees
To cover non-refundable payment processor fees and order processing time, customer-initiated cancellations will incur a $10 processing fee, deducted from the refund amount.
To check your route, confirm that temperatures at your destination are in the safe range — 35°F to 90°F for fish orders, or 50°F to 80°F for shrimp-only or plant-only orders. If they are, your route is virtually guaranteed safe — so orders placed by Friday will ship that Monday.
Temperature-Based Shipping
Safe transit conditions: We monitor weather forecasts and ship only when several consecutive days are within safe parameters for the fish, shrimp and plants. We hold shipments when the route isn't safe, notify you immediately, and ship as soon as conditions allow.
Fish orders
Shipped only when temperatures along the entire shipping route are between 35°F lows and 90°F highs (the operating limits of heat and cold packs)
Insulated packaging with heat or cold packs included as needed
Shrimp-only or plant-only orders
Shipped only when temperatures along the entire shipping route are between 50°F lows and 80°F highs

Once your fish or shrimp arrive, they must be properly acclimated to your tank’s water parameters before release. We strongly recommend using the Drip Acclimation Method, as it provides the safest transition and minimizes stress.
After acclimation and introduction to the tank, feed your fish as soon as possible. To prepare for shipping, fish are not fed for a day prior to shipment, and combined with transit time, this may result in 2–4 days without food.
It’s normal for shipping stress to temporarily affect appearance and feeding:
Male color may initially appear lighter
They may eat lightly or pick at food initially
This typically resolves within a few days. Once fully acclimated, males will display full coloration and feeding will be vigorous. Maintaining a consistent routine (lighting, feeding schedule, and stable water conditions) helps speed acclimation.
Drip acclimation slowly introduces your tank water into the shipping water, allowing temperature and water chemistry to adjust gradually. This significantly reduces shock and potential losses due to improper acclimation.
Step-by-Step Instructions
Prepare a drip cup
Use a plastic cup (such as a sports drink cup) and insert 3–4 inches of airline tubing through the side.
Add tank water
Fill the cup with water from your aquarium and warm it slightly (5–10°F above tank temperature) to account for cooling during the drip process.
Prepare the fish container
Place the fish and shipping water into a separate container. Remove some water so only about 1 inch remains, just enough to fully cover the fish. Cover the container to prevent jumping – this is critical.
Position containers
Place the fish container below the drip cup of tank water.
Start the drip
Begin dripping water slowly from the drip cup into the fish container.
Increase volume gradually
Continue dripping until the container holds at least four times the original volume of shipping water. Water chemistry and temperature should closely match your tank at this point.
Final check and release
Confirm the Endlers aren't distressed, then gently pour the fish into the aquarium.
If your order contains more than one bag of fish, please follow these critical steps to ensure their health:
Drip acclimate each bag individually. Do not combine fish from different bags into a single container before or during the process.
Why this matters: Water parameters can vary significantly from one bag to another. Acclimating each bag separately is the best way to reduce shock and prevent potential losses during the transition to your tank.
