Fish Quarantine Process
At 10 Gallon Fish Tanks, we take the health of our fish seriously. Every fish we bring in undergoes a strict 2-4 week quarantine process to ensure they are free of parasites, fungal infections, and bacterial diseases before being introduced to our main tanks.
During this quarantine period, fish are treated with the “Med Trio” as needed:
• Paracleanse – Targets internal & External parasites like worms and protozoans. Things like fish lice, tapeworms, hole in the head, skin and gill flukes.
• Ich-X – Treats external parasites and fungus. Treats Ich and white spot disease.
• Maracyn – An antibiotic that combats bacterial infections, preventing issues like fin rot, skin redness, open wounds, swollen eyes etc.
This quarantine protocol ensures that every fish we sell are healthy, acclimated to Tennessee water, and ready to thrive in their new home.
