Scaleless fish are also sensitive to this medication to a lesser extent. It is recommended to use half the dose for them.

What We Don’t Like About Seachem Cupramine Copper 250ml
People have exceeded the recommended doses that are toxic to the fish. The medication is measured in drops, which makes it less accurate.

While many liquid treatments can stain, this one doesn’t appear to.
What We Don’t Like About Kordon Ich Attack Treatment
Most people find that Kordon Ich Attack Treatment successfully removes Ich after just a few doses, but there are too many reports claiming it to be ineffective. This may be due to the alternative ingredients from normal medications, but it is the price to pay for an invertebrate-safe product.
- Usable in saltwater and freshwater
- Safe for invertebrates
- Targets multiple pathogens
- Does not stain
- Not as reliable as other products
A way around this is to separate your infected fish to a quarantine tank and treat them there, but not everybody has the extra equipment for this.

Those of you with invertebrates may have to try Kordon Ich Attack Treatment. Due to its herbal nature, it is safe for most creatures. It isn’t the most reliable though, so separating your fish and trying a different product could be more effective.
People with reef setups may want to try Ruby Reef Kick-Ich Aquarium Water Treatment. It is fine for use with corals. Hopefully, you will have caught the disease early because this treatment takes longer to eradicate diseases.
