Before you buy any fish, you will need to set up the tank. A basic set up includes: a tank, filter, hood/light, heater, gravel and some decor. The tank should run without fish for at least 4 to 6 weeks. This gives it time to cycle. The Nitrogen Cycle is critical to the health of the tank and any fish you will be keeping. During this time, beneficial bacterial will populate the filter and substrate (gravel). These bacteria will be responsible for breaking down fish wastes and other wastes (uneaten food, dead plants, etc.). You will need a home test kit to monitor water chemistry (ammonia, nitrites, nitrates, pH) or you will have to submit water samples for testing. Most pet stores will do this for free or for a small fee. At first, you will see high levels of ammonia and nitrites. Over time, as bacteria grow, these levels will drop. When ammonia and nitrites are at 0 ppm and nitrates are below 20 ppm, you can consider adding fish. Regular (every 1 or 2 weeks) partial water changes as we

A fish tank will need a filter, a light/hood and a heater. Make sure the filter is rated for at least twice the tank volume. The heater should be adjustable since water temperature will depend on the species of fish. Good "starter" fish include Tetras, Mollies, Danios or Tetras. A new tank should be set up and left running empty for several weeks before adding fish. A pinch of flake food can be sprinkled in daily. This "cycling" will allow a population of beneficial bacteria to colonize the tank and filter. These bacteria will break down wastes (ammonia, nitrites and nitrates) which are toxic to fish.

Guppies or Neons are excellent "starter" fish. Care is simple and they are inexpensive. A standard 10 gallon tank is recommended to start. Most people don' t realize the amount of "work" needed to maintain a tank. Filter maintenance, monitoring water chemistry, water changes, monitoring fish health and providing a balanced diet are just a few items that need regular attention to keep a tank thriving. Even though fish aren't as cuddly as cats and dogs, they do have their own personalities and even respond to their owners, especially at feeding time! Studies have shown that simply watching fish in a tank can lead to a reduction in both heart rate and blood pressure. It is quite relaxing.

Thanks for reaching out about Nemo and including photos. There is no evidence of Ich in the photos. Have you tested water quality for pH, ammonia, nitrites and nitrates? Correct problems. If having difficulty breathing (slow gill rate) add an air stone. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Good luck.

It sounds like you need to take a trip to your local pet store. The clerks there can help you pick out an appropriately size tank with proper filtration and heating that can help keep Sushi healthy. They can also let you know what water treatments you'll need for the water in your area, as well as test any water you bring it to see if it is OK for Sushi to live in. Pet stores will also carry commercial goldfish food which is a balanced diet that is given to them. It should have feeding instructions on it so you know how much is appropriate to give to Sushi.
