Top freshwater fish diet guides? Another small fish in our list is a Platy – a small freshwater fish that grows to be only 3 inches. Platies make good companions to other small fishes. They have interesting color patterns that attract many fish breeders. Despite their size, they need to be kept in a big tank, especially if they are kept with other fishes where there is a tendency to be overcrowded. Platies are good jumpers, which means that your tank needs to be covered to keep them from jumping out of the aquarium. They will eat all types of fish food.

Prepare everything you need for cleaning in advance so that you don’t lose time. Here is a sample list of things that you may need: nets, a temporary fish tank, freshwater, a clean brush, an algae cleaning pad, a siphon, a water conditioner, a unique tool for aquariums, clean rags and towels. Prepare a place for cleaning the aquarium. Lay some waterproof cloth on the floor so that the story is not covered with water. The main thing is that the aquarium should stand in one place, since when carrying fish, they will experience stress, and dirt will rise from the bottom, and the water will become muddy.

What Are the Different Kinds of Fish Tanks? When it comes to fish tanks, there are many different types to choose from. You are likely familiar with the two main divisions – freshwater and saltwater. What you may not realize, however, is that even these categories can be further divided. Coldwater freshwater fish are also popular with fish hobbyists. The ubiquitous goldfish is a good example of a coldwater freshwater fish. Tropical marine tanks and reef tanks are also very popular – think of fish like the clownfish and brightly colored tangs. Not all marine fish are tropical, however — a popular coldwater marine fish is the Blenny. Marine fish tanks are challenging to maintain, namely because the water chemistry is hard to manage (and we’re not just limited to the salt levels here). Marine fish are usually more sensitive to changes in their environment because out in the open water they aren’t usually subjected to big changes. Read even more details at fish pets advices.

Frequent water changes replace minor and trace elements that are pulled out of the water by corals. This includes elements such as potassium, iron, strontium, and other lesser known elements found in salt mixes. Major elements such as Alkalinity, Calcium, and Magnesium are commonly added back in to the aquarium by dosing, and are removed much faster than water changes can replenish (for more information on major elements, see the article Understanding and Balancing Alkalinity, Calcium, and Magnesium in Saltwater Aquariums). Though major elements are easily maintained through dosing, minor and trace elements are much more difficult to maintain this way. This is because measuring the consumption of each minor and trace element and adding it to the water is both expensive and time consuming. Conducting frequent, weekly, water changes of 15 – 20% of the total water volume of the tank will help replenish the lesser measured minor and trace elements. Though you may need to dose these elements if you try to keep difficult, high end corals. However, for most of us in the hobby, frequent water changes will help your aquarium maintain these levels.
