As for what kind of tank you will need: Basically a square fish tank, do not get a bowl. You will likely need a heater and an air pump, and a thermometer, It is easiest to by a complete kit at a pet shop. As for size of tank: The bigger is always the better....however a minimum size will be determined by the type of fish and their average size they will grow into, So once we know what type of fish you have and how many, we can tell you how big your tank needs to be and what type of "furniture" (rocks, plants, gravel) you will need.

It should be okay to use these tanks as long as they have proper filtration, lighting...etc. Round bowls typically don't have filtration, lighting...etc and that's what will adversely affect the water quality. I hope this helps.

Monitor water chemistry using a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Pristine water quality is the foundation for healing and recovery from infection or injury in fish. You can use plain aquarium salt (NOT table or Epsom salt) as a general tonic to reduce stress, improve gill function and aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup or two of water and gently pour it into the tank. Treat for 14 days then reassess the condition. An "all in one" product, such as Lifeguard (by Tetra), can be used concurrently to treat infection or parasites. Find one in the aquarium section of the local Petco. Follow label directions carefully and remove

Gold fish can make great fish but they can live up to 25 years and require a large tank that may need to be upgraded if they grow too large. Do get at least 2 fish.

If you are getting hard water deposits, use a utility razor and gently scrape the deposit off the glass. When you're doing a water change, if the water level drops below the deposits, use a cloth dampened with plain vinegar and scrub. Be careful to not allow any vinegar into the water. Wipe it well with a clean cloth to remove any vinegar residue and refill. Ideally, the tank should be emptied, sprayed with vinegar, sit for 10-20 minutes then scrubbed or scraped.
