How to Give Your Tropical Pet Fish A Salt Bath
By Eddie Waithaka @aquariawise
Salt in a freshwater fish tank may come as a surprise if you only started keeping finnies at home.
Well, it is safe for most tropical fish if used in moderation, and the dosage match the species you have in your tank.
Salt is used in tropical fish tanks as a remedy for bloated or constipated fish, to treat swim bladder, dropsy, nippings, and fin rot, and when you need to buffer your water hardness.
Of course, Epsom, table, and aquarium salt can be used interchangeable, but the results vary depending on the use.
I prefer aquarium salt baths for parasites such as ick, nippings, fin rot (more so if there is a risk for secondary infections), and to buffer my water hardness, and Epsom salt baths for bloating, constipation, swim bladder, and dropsy because it is a laxative and effective at reducing swellings.
A tablespoon for anywhere between 2 and 10 gallons of water is useable, but it depends on the fish you have and the use.
I use a higher concentration when keeping hardy, salt-loving fish like cichlids, platies, guppies, and mollies, or when treating bacterial ailments and parasites such as ick.
My fish salt baths last 2 to 4 minutes in a high saline solution (a tablespoon in 2 to 5 gallons of water) and 5 to 7 minutes in a weak solution (a tablespoon in 5 to 10 gallons of water) on average.
Thats said, it’s advisable to watch your fish while in the salt bath to ensure they’re safe and remove them if you notice they are struggling.
What Does A Salt (Bath) Do for Fish
A salt bath does a lot for fish, and you will most likely achieve more than you are targeting with an occasional dip or bath.
For the most part, it will relieve stress in fish, fight parasites, bacterial infection, heal fin rot and nippings, relieve bloating and constipation, reduce swelling, and ease dropsy and swim bladder disease when coupled with other remedies.
Essentially, aquarium and Epsom salt are magical solutions to many fish problems. Below is everything you can achieve with an occasional salt bath for your fish.
- Improves gills function
- Reduce uptake of nitrates (nitrate poisoning)
- Aids the formation of slime coat
- Decreases osmotic stress
- Reduces bloating and constipation
- Effective aganist some external parasites
- Effective aganist some external bacterial and fungal infections
- Ease the effects of dropsy and swim bladder disease
- Heal fin rot and nippings
- Ease inflamation and swelling in fish
Now, please note different salt applications will have varying effects on your fish, and the result you’ll get from Epsom salt will not be the same with what you achieve with aquarium salt.
In emergency cases, you can even use ordinary table salt with decent results.
How to Make A Salt Bath for Your Fish
To prepare a salt bath (dip) for your fish, you’ll need to start by dissolving a tablespoon (3 teaspoons) of salt per 3 gallons of water. Make sure the ph and temperature match your tank water.
You can even use water directly from your aquarium to make sure your fish don’t get stressed by the change occasioned by using water from another source.
Pour salt into the water and stir until it’s completely dissolved, then using a clean container (or net), get your fish out of your aquarium and place it (them) in the saline solution.
Set a timer for 5 minutes to give the solution enough time to work your fish.
The fish may seem a little distressed and twist sideways from time to time, which is normal. However, if your finny tips on its side and can’t get up, remove it from the salt solution.
Elevated gill movement, gasping, and lethargy are other signs your fish is stressing and needs to be moved.
After five minutes have elapsed, remove your fish from the saltwater solution. Transfer it to a holding tank with the same parameters as your main aquarium (and the solution).
Place him back into the main tank after 1 to 2 hours, assuming your fish is swimming and acting as expected.
You can use a concentration of 1 tablespoon of salt per gallon (or 2) of water for the next level of treatment if your fish is not better after an initial bath, but make sure it can tolerate that much salt.
How Much Salt Should You Add to Your Fish Tank
Some owners choose to add salt in their fish tank in place of a salt bath for their finnies, which is safe and recommended, especially if your stock likes hard water.
The appropriate amount is anywhere from a tablespoon of salt for every 5 to 10 gallons of water, though less is better when keeping scaleless fish.
Malawi cichlids, guppies, platies, and mollies love salt and will survive in water with up to a teaspoon of salt per gallon of water. Just make sure that is not the environment to keep them in all the time.
Is Epsom Salt Good for Fish
Yes, Epsom salt is good for fish to remedy bloating and constipation, but compared to aquarium salt, it is the lesser solution for fighting bacteria, fungus, and parasites like ick.
As with any natural cure for fish conditions and ailments, Epsom salt should be used in the right concentration to keep the water safe for your finnies.
A tablespoon or two is recommended for use in a tropical freshwater fish aquarium, and remember to dissolve the salt in a cup before adding it to your tank.
Avoid too much of any kind of aquarium salt because it may cause stress to some internal organs, gills, may result in an overactive slime coat, and lead to dehydration.
In terms of buffering your water hardness, Epsom salt won’t raise it too much, but it will still bring it up enough to stress finnies that prefer very soft water.
Of course, that is if you add more than the recommended amount.
Can You Use Too Much Salt in Your Fish Tank
As I’ve stated a couple times before, the ideal amount of salt to add in your freshwater fish tank, whether as parasites, bacteria, bloating, or constipation treatment, is a tablespoon of salt for every 5 to 10 gallons of aquarium water.
You can increase the concentration to a tablespoon of salt for every 2 to 3 gallons of water for salt baths, but only for fish like mollies, guppies, platies, and African cichlids that don’t mind things on the saline side.
Remember to match your salt bath durations to the fish species you have and avoid salt dips for scaleless fish and inverts like shrimp and snails.
