1 Choose a quality pellet. When deciding what to feed your koi, think of it in two parts—base diet and supplementary diet. The base diet should provide all the essential proteins, fats, and most of the vitamins and minerals your koi need to survive. Commercial pellet food is the most reliable, convenient, and healthy option for a base diet.

1 Keep track of age. In order to determine the correct amount to feed your koi, you need to know the age, length, and weight of each fish in your pond, in addition to the water temperature. Find out how old your koi are when you purchase them and keep track of their age over the years. Keep a notebook or file with a description of each fish next to their stats.

Select common, easy to grow freshwater plants.Freshwater plants have different lighting requirements and can sometimes be difficult to maintain. Luckily, there are some easy options for beginners that will create the look you want in your aquarium. Look for plants that are labeled as Echinoderms, Lilaeopsis, Anarchies, or Anubis.

Feed in small amounts.Calculating the amount of food to feed your koi is the most accurate way to determine how much food to provide, but you should also pay attention each time you feed your koi. Feed your koi small amounts at least twice a day.

• You want your koi to be able to eat all of the food you give them in a short amount of time (less than five minutes).
• Overfeeding koi can cause serious health problems like severe negative impacts on the liver and other internal functions.
• Pre-portion your fish food to keep from overfeeding.

Regulate the water temperature.Because silver dollar fish tend to naturally inhabit waterways in South America, they typically thrive in slightly warmer water temperatures. Use a water heater and keep a thermometer in or near the tank so you can regulate the temperature as needed.

Choose the right tank size.One of the biggest factors in a fish's survival and wellbeing is the environment it lives in. Housing your silver dollar fish in a small, cramped tank can be very uncomfortable for your pet, and if you have more than one fish in the tank they may begin to compete for resources.

Identify the sex of your fish. If you're interested in breeding silver dollar fish, you'll need to learn how to identify the males and females of the species so you can provide a suitable mate for your fish. Male silver dollar fish tend to have an anal fin that is longer than females. The anal fin is usually tinted red on most males as well.

Check the temperature.Turtles are cold blooded reptiles and will not eat if the temperature is too cold. If you have an indoor box turtle

Feed your turtle a balanced diet.Your turtle should eat a balanced diet comprised of fruits, vegetables, and meat. If your turtle is aquatic, its diet should be 65% to 90% meat (e.g. earthworms, snails, mollusks, frozen pinkie mice
