A lot of people try to keep fishes to be their pets but most of them failed due to the wrong practice they do. Different types of types and it's characteristic will be considered as follows.
The type of fish is one to be innovative. Each fish has its own characterize. Some of them are territorial some of them are capable of community tanks. First thing first think of the nature of fish how to feed them what kind of food they eat.
Next will be their habitat. Imagine them what tho they like in the wild. Other fish keepers doing ponds, aquarium, or maybe in a plastic container. Some of them innovate the types of the tank they set up like trapal ponds some of them put in a plastic container. The size matter with fish in terms of small fishes require small tank the bigger the fish the bigger their tank.
Another aspect to be considered is the water of course. They called it water parameters were in the ph level of water should be monitor because this can cause the of fishes when it is not well monitor. Cycling water before putting some fishes are important to because we need to cycle to water to build up good bacteria for our fish. Setting up an aquarium with new water will give a big risk for our fish usually we do cycling for one week and use stock water and before you put you're newly buying fish in the tank you need to acclimate the fish for them not to be temperature shock and stress.
Then you need also what food they need each fish has it's a distinct type of food. Live food is really recommended for them to grow will and enhance their color too. Live food contains high in protein that build up their body.
You need also to change the water of your tank because stagnant water is not the same in the wild that is all-natural this time we need to change the water to minimize the toxicity of water and ammonia due to their poops and u consume food.
Filtration also is important to purify the water for our fish to become healthy. Some of them use commercial-like sump or filtration tank some of them doing it like in a natural way like putting some plant and it provides also oxygen to our fish. Lastly, we need time and patience because this hobby is not easy we need to have time for them to care to clean to see them and it's really fulfilling to us see form buying small fish watch them grow bigger and bigger that why it really hard to see fish died.
