Frequently asked questions

More questions and answers

Does aquarium salt harm plants?

Many freshwater plants are sensitive to salt, so prolonged use can make leaves melt or kill plants. When salt is needed, it is more often used in a separate hospital tank without plants.

How should I care for an old aquarium fish's health?

Stable water, easy-to-eat food and less competition from faster tank mates matter especially for old fish. They may be slower and paler. Make sure they get food, and do not mistake sudden signs of illness for old age.

How should a fish quarantine tank be cleaned after use?

Drain it, clean the tank and equipment, disinfect if needed with a product made for aquarium equipment as the label directs, then rinse very thoroughly and let it dry. If sick fish were in it, it is worth asking a vet about disinfection.
