Questions
Is it a replacement for a vet?
No. It's a practical guide for the most common freshwater problems. Always follow the label on your medicine, and ask an aquatic vet or experienced fish store when you're unsure.
Does it cover saltwater fish?
No, it's for freshwater only.
What if it isn't for me?
Contact me within 14 days and I'll refund you.
