It's crucial to avoid self-treating your fish, as incorrect treatment can be fatal.
Here's why:
* Ich is a parasitic infection: It's caused by a protozoan parasite called *Ichthyophthirius multifiliis*.
* Treatment options vary: The duration and type of treatment depend on the severity of the infection, the size and species of your fish, and other factors.
* Incorrect treatment can be harmful: Using the wrong medication or dosage can harm your fish and potentially make the infection worse.
Instead of relying on general information, contact a professional who can assess your fish's condition and recommend the appropriate course of action.
