Fish are generally regarded as the easiest pets to keep. There are still however a number of things to remember to keep your finned friends happy and healthy.

 

A balanced diet for your aquarium fish is essential for their survival and good health.

Proper aeration, water temperatures and ph levels are vitally important.

1. What types of food are available for pet fish?


A balanced diet for your aquarium fish is essential to their survival. The feed should preferably be kept dry. You can choose from flake foods and freeze-dried foods.

Flake foods -

These vary largely in price and in quality.

Freeze-dried foods -

These are favorites for aquarium fish. They have single animal-ingredients like mosquito larvae, blood worms and Tubifex worm. This is not a complete food but works well in combination with flake food and other types of freeze-dried foods.

Tubifex -

This is a traditional favorite food relished by most fishes.

Remember - do not over-feed or give your fish treats with high fat content.

Generally small fish living in a warm water aquarium should be fed flake foods and some freeze dried food such as blood worms. Larger fish living in warm water aquariums should be fed pellet food.

2. How should you introduce a fish to its new aquarium?


When you bring home your fish, it's likely that it will be in a small plastic bag - do not transfer the fish straight into the aquarium. Allow your fish to regulate its temperature - to do this you will need to float the bag in the tank for about half an hour then open the bag to let your fish venture out at its own pace.

3. How often should you change your goldfish tank water?


Generally speaking, you should change some of your goldfish’s tank water once per week. Only change about a third at a time. Adding tap water too quickly or when it is a very different temperature to your tank water can shock your fish. A stressed goldfish will have a lowererd immune system and increases its chance of getting ill. You should regularly use a test kit to keep to monitor ammonia or nitrite levels and treat the water accordingly.

4. Can goldfish be kept with other types of fish?


It is best to keep goldfish with goldfish. If you must add another type of fish to your goldfish tank, White Cloud Mountain Minnows or Zebra Danios would be best. These fish like to live in schools so you would need to add at least 6 or so - that will mean that your fish tank will need to be large enough to house all of the fish comfortably. Your goldfish should also not be too big - if the others can fit into their mouths they will get eaten!

5. What coldwater fish are small enough to be kept in an aquarium?


Apart from goldfish, some of the small to medium fish suitable would be Barbs, Bloodfin Tetra, Guppy, Danios and Minnows. Coldwater fish do not require heated tanks.

6. Should you change your fish aquarium water?


It is very important to keep your aquarium water clean. There are a few tools that could help you do this - Siphons, Water Changers & Gravel Cleaners can help make routine water changes efficient and stress free. Water changers can help you to replace and clean water on a weekly basis (do not replace more than 30% at a time). You can also vacuum the gravel and bottom area of the the tank, where the old bits of food and waste tend to accummulate. You will still need to deep clean your tank and remove algae at least once a month, but keeping your water changed and fresh will help with maintenance.

7. Can you overfeed fish?


Yes ! Fish always act like they are hungry and they will just keep on eating. They say that when you feed fish, they should only eat as much as they can in 2-3 minutes (for one meal a day). The remainder of the food should be removed. Uneaten food decomposes quickly, releasing a lot of organic and inorganic compounds that will wreak havoc on the aquarium's chemistry. The aquarium water can become cloudy, there may be an increase in algae growth and uneaten food will pollute the water.

8. What should you do in the event of power failure?


If the tank is not overcrowded and your fish are not overfed, you can possibly go for a few hours without added oxygen. Do not feed your fish during this time, as this activity uses oxygen - keep your fish as calm as possible, keep the tank room dark. A battery operated air-pump is a useful backup in such situations. Try and keep the water temperature constant - cover with blankets and towels to help with insulation. Clean the filters.
