DR. BASSLEER BIOFISH FOOD PROFESSIONAL TREAT aids the recovery of ornamental fish during and after medical treatment. The product contains fresh Garlic, which is rich in allicin and manganese, as well as Aloe vera and the added value of Peppermint, Thyme, Mugwort and Chickweed. These herbs strengthen the defenses and power of resistance of the ornamental fish and therefore help to keep the fish healthy. Emaciated fish quickly regain weight.
See the study on use of herbs to help to cure fish diseases, especially antibacterial (replacing antibiotics) and our herbs that we mix with the granulates are mentioned)

These wild catfish, Corydoras melini, had 2 worm infections that weakened and damaged the fish: gill flukes and internal worms.

With great surprise and sadness we were informed the passing away of Heiko Bleher.
We will remember him as significant contributor to the global aquarium industry & hobby! Especially his discoveries during his exploration trips deep into wild rivers and lakes! Since he was also often controversial it made discussions interesting & challenging! He will certainly be remembered by his publications and the many species he helped introduce to the hobby!

Here we selected several studies to share knowledge about the use of medications against gill flukes, Dactylogiridae. Here it was a gill fluke, called Dawestrema, found on Arapaima gigas (Pirarucu) that has been treated with baths of Trichlorfon and Garlic. Als Garlic was used to treat the Protozoan, ciliated parasite, Trichodina with great succes! Lessons to be learned about the practical use of medications. See later on my study on the use of Garlic to use as fish medication.

Maybe only few Aulonocarra Malawi Cichlids, are badly infected and suffer while most of the others can survive for a long time when kept in good condition. We found tubercles in the organs, most likely caused by Mycobacterium (fish tuberculosis, FishTB) and treatments are not very effective. Some tried antibiotics such as Kanamycin, Rifampycin or others (see my books).
Recommended to improve immunity of the fish with a functional fish food;
