Healthy fish are the heart of Tropical Fish Co. We love this hobby, we care about the fish and the people who keep them, and we treat every shipment like it matters. Our tanks are clean and oxygen rich. We watch closely, we take our time, and we only list fish that are active, eating, and stable. This page explains how we care for fish from the moment they arrive to the moment they head to your aquarium, plus simple steps you can follow at home.
We believe in clean water, steady routines, and clear observation. Stable water beats perfect numbers. We do not chase parameters unless there is a special breeding or health need. Every decision puts fish welfare first. We truly love these animals and this hobby, and that care shows in how we work.
Intake and temperature match
New arrivals are floated to equalize temperature, then moved into clean holding tanks with matched water that is clean and oxygen rich.
Initial assessment
We check respiration, posture, skin and fins, and response to food. If anything looks off, we slow down, adjust care, and give the fish more time to settle.
Microscope checks and proper medications
When needed we use a microscope to screen for parasites. If treatment is called for, we use the proper medication for the issue at species appropriate doses for the correct length of time. We do what is needed for the fish, and we monitor closely, adjusting with a clear reason.
Quiet observation
Fish rest with lower light and minimal disturbance while tanks stay clean and oxygen rich. We watch for steady breathing, normal behavior, and consistent appetite.
Feeding and conditioning
We offer foods that match each species. This includes quality pellets, frozen foods, live foods, algae rich diets for grazers, and botanicals for detritivores. Several small feedings help fish regain strength without polluting the water.
Minimum timeline
Fish remain in quarantine for at least two weeks. They may stay longer if they need extra medication or more time to settle, eat well, and gain weight.
Release criteria
We list a fish only after it is eating, active, holding color, showing clear eyes and fins, and passing final visual checks.
Quarantining fish this way takes time, food, filtration, medications when needed, and careful staff attention. It does raise our costs. We believe this process is worth it because it produces healthy fish that are far more likely to thrive in your tank. We would rather invest more upfront than cut corners and risk your experience at home.
We do not rush fish to sale. We do not chase pH or hardness to match a specific river unless there is a clear reason such as breeding. We do not use harsh treatments on sensitive species. We do not ship a fish that is not fully ready.
Before shipping, fish are rested off feed for a short period so the water stays clean in the bag. Bags are packed with pure oxygen and secured in insulated boxes with heat or cold packs as needed. Boxes move early in the week so time in transit stays short.
Before arrival
Set up a simple quarantine tank if you can, even a small bare tank with a seasoned sponge filter, a heater if needed, a few hides, and a tight lid. Keep the water clean and oxygen rich. Use separate tools for this tank to protect your display.
On delivery day
We do not advocate drip acclimation.
We share general ranges for temperature and pH, but we do not recommend chasing numbers. Aim for clean, oxygen rich water and consistent temperature. If you are breeding a species that needs special conditions, reach out and we will share what has worked for us.
If a fish looks off after arrival, send a quick photo or short video. The more we can see, the faster we can help. For live arrival issues, follow the steps on our Live Arrival Promise page so we can take care of you quickly and fairly.
