Question of the Month: Can I use the Herbtana and Artemiss together? I am getting new fish and want to treat them just in case they have parasites and/or bacterial diseases. What about the TheraP? Response: Herbtana and Artemiss have been very effective at helping to prevent infection in fish when being introduced to new systems. There are many importers and dealers using these products for this purpose since they are all natural. The recommended program is to dose one product in the morning and the other in the evening (or approx. 12 hrs apart) for a period of 2 to 3 days. This will act as an immune system stimulant and destressant. Microbe-Lift/TheraP beneficial bacteria supplement for the aquarium is also an excellent product to use not just when adding new fish, but ongoing to promote good fish health, color, and disease resistance, among other benefits.
