In this guide on the 7 best beginner fish for 10 gallon tanks we will show you how to pick the best fish for your 10 gallon aquarium and what to look for in a healthy fish.
What to know before stocking your 10 gallon fish tank.
There are some things you need to know you start stocking your 10 gallon tank for the first time. For example you want to decide how many fish you want to keep in your tank. Do you prefer one species or multiple species, and is your tank going to be planted?
How many fish can you put in a 10 gallon tank?
A lot of experts are going to tell you that you should only have one inch of fish per a gallon of water but I can tell you that is not true. One 10″ fish is going to die in your tank and you should not have 20 small fish less than half a inch unless you are prepared to have lots of filtration and do a lot of water changes. On average if you can have up to 10 small fish in your tank if you have adequate filtration and a way to control the bio load.
Will fish stay healthy in a 10 gallon tank?
Fish will stay healthy in a 10 gallon tank as long as you monitor the water parameters. The ammonia and nitrites should stay at 0ppm and the nitrates should be between 0-10ppm. If you keep your fish tank water parameters at these levels you fish will stay healthy and active in a 10 gallon tank
Can you put different species in a 10 gallon tank?
You can put different species in a 10 gallon tank and in my opinion you should. In my experience the 10 gallon tanks I had with multiple species stayed the healthiest and I had less over water issues with the tank. As long as you do not overstock the tank, and pick fish that prefer different levels of the tank you will find that a 10 gallon tank can be just as colorful and diverse as a much larger tank.

Corydoras is a type of fish that is popular among people who keep fish in tanks at home. These fish are pretty and good to have in a community tank because they get along well with other types of fish and aren’t aggressive. They are peaceful fish and it’s best to keep them in groups of 4-6 or more. These fish mostly eat food that sinks to the bottom of the tank like sinking pellets, live or frozen food. Sometimes faster fish will eat all the food before the corydoras can get to it, so you have to be careful.
Corydoras like water that is soft and a little bit acidic. They can survive in different types of water but don’t do well in water with high levels of nitrate. High nitrate can make their barbels (whiskers) infected and they won’t work well. Sharp rocks or gravel can also hurt their barbels. But these fish can be kept in tanks with gravel as long as the edges are not sharp. They also like to have a spot on the bottom of the tank with no rocks or gravel where they can find food easily. Some people think that you can’t use salt to treat sick corydoras, but it’s not true. Salt can help get rid of a sickness called ich. These fish are easy to take care of and are peaceful, strong, active, and fun to watch. Sometimes they swim to the top of the tank to take a quick breath of air, but it’s normal and nothing to worry about. But if they do it a lot, it might mean the water is not good.Regenerate response
