Quarantine Tank aka Hospital Tank


Your fish is ill!

Will you treat the diseased fish in the same tank?

The answer is NO!!!

It could prove fatal for other healthier fish.

And sometimes it becomes a big headache for any fish keeper either he is beginner or expert on how to keep the other fish protected from the diseased fish.

So, what to do in this situation???

Simply you will keep you diseased fish in a separate tank, and the tank which he designed to treat the fish separately is called “Hospital tank” or, in other words, “Quarantine tank.”

Whatever you call it, the purpose is the same in both cases, i.e., to protect and treat your fish.

Here, we will provide you the complete guide on how you can set up the hospital tank in a limited budget.

Keep in Mind: While designing a hospital tank, it is not essential to develop it identical, but you can mimic the hospital tank with a simple fish tank.

What is the Purpose of Hospital Tank?

If the diseased is sharing the tank with other fish, the first thing that should be done is to separate the sick fish from the healthy tank mates, except on account of some outside parasitic contaminations like Ich or Velvet, in which the whole tank would need to be treated. This is done trying to control the spreading illness to the next fish in the tank.

It additionally keeps the sick and weakened fish from being singled out by his sound tank mates.

Step By Step Guide How To Setup Quarantine Hospital Tank?

For Setting Hospital fish tank, you need some must-have things to kick start a quarantine tank. list of things is below

1) Aquarium / Tank

To set up your hospital tank, start by filling it with water as near the temperature of your main tank. But first, all selection of tank is essential.

I like to utilize an all-glass aquarium, however, when necessary, any watertight compartment, for example, another Rubbermaid holder or plastic can, that won’t leech undesired compounds into the water, can be utilized. The inhabitants of the tank will be awkward in a little tank with a brilliant hued base and foundation.

In case you’re running a 10-gallon tank, utilizing approx. 3 gallons for the emergency clinic tank will kick start the filtration and not harm your presentation tank. If the tank is bigger, you might have the option to remove the whole 10 gallons for your hospital tank.

2) Substrate

A substrate (gravel) isn’t required in a Hospital/Quarantine Tank. The utilization of gravel scatters a portion of the water limit in the tank, so your 10-gallon tank may just hold 8 gallons of water after you include the gravel. This makes it increasingly hard to calculate how much drug to add.

3) Filter

I suggest utilizing a sponge filter. They are modest, easy to clean, simple to use, and are productive organic channels. Connect the sponge filter to the air pump with enough air ability to keep the water surface moving.

4) The Lighting

The lighting is not very important in the hospital tank. If you want to light it, then avoid being brightly lit.

5) The Heater

The good quality heater is also essential in the hospital tank to maintain a constant temperature. Also, use a reliable thermometer to monitor the tank temperature.

6) Plants And Decorations

Mostly fish do not feel safe in a bare tank. Add decorations but to a minimum level to make the fish feel safe.

As the purpose of the hospital tank is to add medications to treat the diseased fish. So it is highly recommended not to use live plants.


Always use artificial plants in the hospital tank

7. Other Equipment’s

Nets, siphons, and other tank equipment should just be utilized on.

The Hospital/Quarantine Tank should not use on your different tanks since illnesses can be transmitted from tank to tank when sharing such gear between them.

If there has been an outbreak of the disease in your Hospital/Quarantine Tank, at that point, such equipment ought to either be appropriately sanitized or disposed of.

8. Tank Cycling

If you are a beginner, then you may have a question in mind, does a quarantine tank need to be cycled. Similarly, as you do in other aquarium arrangements, the Hospital/Quarantine Tank needs to experience the cycling procedure. However, this would make bothersome pressure the debilitated or recently buy and, as of now, focused on occupants of the tank. Along these lines, the Hospital/Quarantine Tank ought to be kept cycled.

9. Water Quality Parameters

Water in the Hospital/Quarantine Tank ought to have comparative parameters, particularly pH and GH (general hardness), to the water that the hospitalized or isolated fish is originating from. If this is beyond the realm of imagination, the fish should be acclimatized, that is, gradually gotten used to the water before adding them to the tank.

So from all the above discussion, the basic equipment needed to set up a whole hospital tank is

  1. Sponge filter
  2. Air pump
  3. Thermometer
  4. Heater
  5. Airstone to prevent oxygenation

Medication in Hospital Tank

Ensure that when you do treat with antibiotics, you follow the prescribed course, including all suggested does and full treatment sums (for all fish), particularly when fish improve. This is a point that numerous aquarists don’t follow.

Good-natured aquarists will buy only enough prescription for a couple of portions when three or four are the base required. At that point, the fish may improve to some degree, and the aquarist expects everything is acceptable; however, the fish goes “downhill.”

Resulting medications with a similar anti-microbial are presently not as viable because of the infection pathogen developing a resistance to this anti-microbial.

I’ve had aquarists go up against me, expressing, “I thought you said this drug would work, the fish showed signs of improvement, however, then they became ill again, and now they’re more awful than previously”.

At the point when I burrowed further, I found that just a couple of medications had been utilized, and this is the usual outcome when one treats with most anti-infection agents along these lines.

An exemption is Triple Sulfa (or any Sulfa), which are false anti-infection agents, rather Sulfas are antimicrobials. That said about Sulfas; also are considerably more powerful when the full course is followed.

When a microscopic evaluation is not possible is how the fish responded to medication often is a determining factor in what the disease is.

Three diseases often get confused (for a good reason). However, treatment effectiveness is often a determining factor, see below;

  1. COSTIA: Formaldehyde
  2. VELVET: Copper Sulfate, Acriflavin, Methylene Blue
  3. SPOROZOA: Nitrofurazone (if anything)

Finally, diseases are often misidentified, such as Fungus.

A good example is the use of Nitrofurazone, which is found in different forms in many brands of Fungus treatment. HOWEVER, this is not usually effective for real Fungus/Saprolegnia cases. If you are treating for Fungus and switch to a product containing Nitrofurazone, likely your aquarium has Aeromonas, and care should be taken to prevent this in the future.

Treatment Duration to Keep the Fish in Hospital Tank

After setting a hospital tank, then it’s a big question about how long to keep the fish in a hospital tank?
As you know that the leading cause of the fish disease is stress and poor environmental conditions in transference and breeding of fish. Usually, the newly bought fish is quarantined for 7-15 days, and the diseases fish is kept in quarantine until it got cured completely.

Advantages Of Hospital Tank

There are various benefits to a hospital tank.

The primary advantage of a hospital tank is that you can isolate diseased fish from healthy fish, in this way ending the spread of sickness to other tank inhabitants.

A few infections spread rapidly and might be transmitted through tank water – in cases like this, you will be unable to stop the spread of sickness, yet moving wiped out fish to the medical clinic tank as ahead of schedule as conceivable may assist with diminishing the spread.

Treating in a smaller hospital tank will decrease the expenses. It will likewise forestall the fish in your fundamental tank from unnecessarily being presented to drugs, which helps in the fight against world resistance to antibiotics. So you can limit the treatment only to diseased fish.

Does A Hospital Tank Need To Be Recycled?

These tanks additionally don’t require starter fish to keep up the nitrogen cycle since they are cleared out after each utilization.

When cleaning, it is imperative to recall not utilizing unforgiving synthetic substances like Windex, or different cleaners. In the event that sterilization is important, a weakened fade arrangement can be utilized.

Simply make a point to wash the tank altogether in the wake of utilizing the detergent water, and permit the tank to dry completely before utilizing it once more.

How to set an emergency hospital tank?

At the point when required, fill your isolate tank with water from your presentation; this achieves a water change in your showcase, just as kicks you off with molded water in your isolate tank.

Another great stunt is to keep your wipe media, or cartridges from your capacity channel in your presentation tank. This keeps them colonized with microscopic organisms, and you won’t need to stress over cycling your isolate tank in the event that you need it in a rush.

You can set up a moment built up isolate framework in only a couple of moments if you plan for it.
