Now that you've decided that you want to set up an aquarium, and have done some research into what is necessary to do so, here is some basic information on a few different kinds of fish you can add to your aquarium.
So, you are interested in goldfish? A good choice in my opinion! Goldfish are fun, animated, fish with a lot of personality. A few things you should know...
- Goldfish, when kept healthy will grow! Make sure that they have a big tank, and do not overcrowd them. 1 or 2 in a 10 gallon tank may look sparse at first but soon that tank will be too small!
- Goldfish should be kept separate from tropical fish. Warm water will stress them and they will get sick.
- Buy a lid for your goldfish tank. Golds are very animated and like to jump and splash, especially at meal time.
- Fluorescent lamps are preferable for goldfish; they highlight their vivid colors but do not add much heat to the water.
- Goldfish are bigger than most tropicals and will produce more wastes. Because of this you will need to do more frequent water changes. Also, an under gravel filter may not be able to keep up with all the goldfish poop; invest in a good over the back type power filter. Invest in an ammonia test kit as well as a pH test kit to help you gauge how often to change the water.
- Goldfish do well with a bit of salt in their water, 1 teaspoon per gallon is good to prevent illnesses. If they do get sick, often adding more salt can help them recover, up to 1 tablespoon per gallon.
- Goldfish are one of the most bred and genetically altered fish around. They have been raised in captivity for hundreds of years. With all that time to try new combinations, there are many varieties of goldfish, from plain comets to pop eyes, to fan tails. The sleek comets need more swimming area than the bent looking ryukin types.
- Goldfish do well on a diet of specialized goldfish food, or pond food. They also benefit from periodic additions of plants like anacharis, green water, and vegetables like peas, just 'pop' the cooked pea between your fingers and drop the inside part into the water. If your golds are still small, mash the pea so they can fit it in their mouths.
