When you have ornamental fish long enough, one day you will look at your aquarium and you realize that something is wrong. A fish is breathing too rapidly, is cowering in a corner, has white spots, crooked ends on the fins, or just does not look like itself. Every fish keeper at that moment is of the same fear: “My fish is sick. What do I do now?”

To most hobbyists and even professionals, it is not necessarily about purchasing the medication, but rather obtaining the correct diagnosis and the treatment plan on time. It is precisely at that point that online consultation with a specialised fish health doctor, such as Dr. Gerald Bassleer and the Bassleer Biofish team, becomes game-changing.
