Frequently asked questions

More questions and answers

How should fish medications be dosed in a small aquarium?

In a small tank even a slight error means a large overdose, so accurate dosing matters especially. Use a precise measuring tool and follow the label, and if the stated dose does not suit a small volume, ask a vet rather than guess.

How does marine fish health care differ from freshwater?

Marine fish are often more sensitive to water changes and transport, and many are wild-caught, so quarantine is especially important. Many medications also harm corals and invertebrates, so treatment usually needs a separate tank.

How can new equipment or decorations harm aquarium fish?

New items can carry manufacturing, packaging or storage residues, dust or oil. So rinse decorations, hoses and equipment in clean water without detergent before adding them, and watch the fish more closely for a few days afterwards.
