How to Setup a Hospital Tank? -Aditee Kashikar

Caring for aquarium fish can be challenging, and illnesses are sometimes inevitable, no matter how diligent you are. Setting up a hospital tank can help you manage the situation more effectively and prevent the spread of disease. In this article, we’ll guide you step-by-step on how to setup a hospital tank, ensuring that your fish have the best chance of recovery while keeping the rest of your tank inhabitants safe.

How to Setup a Hospital Tank?

What is a Hospital Tank, and Why Do You Need One?

A hospital tank is a separate, smaller aquarium designed specifically to quarantine and treat sick or injured fish. It plays a crucial role in containing illnesses, preventing their spread, and providing a stress-free environment for sick fish to heal. It also allows for individual treatments without affecting the entire aquarium ecosystem.


How to Setup a Hospital Tank for Your Aquarium?

Here’s a step-by-step guide to setting up a functional hospital tank:


1. What Size Should the Hospital Tank Be?

The ideal size depends on the size and number of fish you have. Typically, a 10 to 20-gallon tank works well for small to medium-sized fish. The hospital tank should be spacious enough for the fish to move comfortably without feeling confined.


2. Do You Need a Substrate in the Hospital Tank?

No, a bare-bottom tank is preferable for a hospital setup. It makes cleaning easier and allows you to monitor fish waste and health more efficiently. The absence of substrate also helps prevent hiding spots for bacteria or parasites.


3. How to Match Water Conditions with the Main Tank?

Use water from your main tank to fill the hospital tank to maintain similar water parameters, reducing stress for the sick fish. An aquarium heater is essential to maintain a stable temperature, while an aquarium thermometer helps monitor it. Aim to replicate the main tank's temperature and pH levels.


4. What Type of Filtration is Best for a Hospital Tank?

A gentle filtration system, like a sponge filter, is ideal. It provides mechanical and biological filtration without causing strong water currents, which could stress or injure sick fish. Avoid filters with activated carbon, as most medications require its removal during treatment.


What Other Equipment is Essential for a Hospital Tank?

  • Air Pump: Improves oxygen levels, especially when medications lower oxygen content.

  • Hiding Spaces: Add a few PVC pipes or artificial plants to provide shelter and reduce stress.

  • Cover Lid: Prevents fish from jumping out, as stressed or sick fish may try to escape.

How to Maintain Water Quality in a Hospital Tank?

  • Perform regular water changes, ideally 10-20% daily, to maintain high water quality.

  • Test water parameters frequently, as poor water conditions can worsen illness.

  • Use a water conditioner to remove harmful substances, especially after water changes.

How to Manage Medications in the Hospital Tank?

  • Administer medications as directed by a veterinarian or product instructions.

  • Always follow the prescribed dosage and duration to avoid under-treatment or resistance development.

  • Observe fish behavior after treatment to ensure no adverse reactions occur.

When Should You Return Fish to the Main Tank?

Allow fish ample recovery time before reintroducing them to the main tank. Ensure all signs of illness have cleared up, and water parameters in both tanks are similar to minimize stress.


How to Clean and Disinfect a Hospital Tank?

After each use, thoroughly clean and disinfect the hospital tank to prevent disease recurrence. Use a mild bleach solution (10% bleach to 90% water), rinse thoroughly, and let the tank air dry completely before reuse.


Final Tips for Setting Up a Successful Hospital Tank

  • Keep the hospital tank ready at all times for unexpected illnesses.

  • Stock essential medications and water conditioners to ensure timely treatment.

  • Regularly monitor fish behavior and health to identify and isolate sick fish promptly.
