White Spots
As the name suggests just noticed the tetra have small white dots on their fins any idea what this is? Kept fish for years and never had any problems with illness (touch wood) any help appreciated as I don't want this to spread to the tank mates.
Hello W...
If the white spots resemble tiny grains of salt, you should be concerned. But, if you catch the Ich parasite in time, a little heat and lots of pure, treated water will very likely take care of the problem.
For the next few weeks, take especially good care of your tank. Raise the water temperature to between 80 and 82 degrees and begin an aggressive water change routine by removing and replacing half the tank water every three to five days. Make an effort to carefully vacuum the substrate where you can. Parasites will live in the gravel as well as float around in the water.
Keep the lights off in the tank and lower in the room if possible. The Ich parasites locate a host by sight.
Salt is needed, but too much will hurt your live plants. So, use a little more than a teaspoon of standard aquarium salt, Kosher salt or commercial canning salt in every 5 gallons of your new, treated tap water. It will calm your fish and boost their immune system.
If you don't use high heat or dose a lot of salt, you can follow this routine for several weeks if necessary to make sure the parasites are no longer a problem.
Just a couple of thoughts to consider or not.
