One inch of fish per one gallon of water in the tank is the accepted guideline for stocking any aquarium. First, it’s important to keep in mind that the size of your fish tank will depend on several factors, including the type of tank you have, the water quality in your area, as well as the fish you’re keeping.

For example, if you live in an area with high levels of nitrates and phosphates, you’ll want to make sure that your aquarium is well-oxygenated. If your water has a high level of dissolved oxygen, then you may need to add an oxygen absorber such as a CO2 tank or a carbon dioxide tank to increase the oxygen level.

In addition, some fish species are more sensitive to oxygen than others, so it may be necessary to adjust the amount of oxygen you add to the aquarium to suit your particular fish. Finally, remember that oxygen levels can fluctuate over the course of a day or even a week depending on the weather and the time of day.

You should keep ollies in groups of 4 or more because they tend to stick together most of the time. If you are going to keep more than 4 mollies, you should get a 20-gallon tank. If you plan to manage multiple colonies, a 45 gallon tank is a good choice.

If you do not have access to a large tank, you may want to consider using a smaller tank to house your colony. This will allow you to have more room to work with, but it will also limit the amount of space you will be able to dedicate to the colony at one time.

For example, if your tank is 20 gallons, and you have a colony of 10 molls, then you would only have room for 4 of them at a time in the tank. You would have to move them to another area of your house, or move the entire colony to an area that is larger than the area you currently live in.

If you want to house 3 Mollies at a time, we recommend a 30 gallon tank as a 10-gallon tank is too small. If you are looking for a tank that is large enough to hold a large variety of fish, then you should consider purchasing a larger tank.

A 30-50 gallon aquarium is a good size for most freshwater fish. However, if you plan on keeping more than one species in your aquarium, it is recommended that you purchase a 50-100 gallon or larger aquarium. This will allow you to keep more fish in a smaller space and will provide you with more room to add additional fish species.

If they are raised in the right conditions, this includes other livebearers like guppies and platies, tank raised tetras and barbs, danios, and even african cichlids. The difference between a pet store aquarium and an aquarium is a matter of personal preference. Some people prefer to keep their fish in their own home, while others prefer the convenience of a store-bought aquarium.

If you’re looking for a tank that’s easy to care for, you’ll want to look for one that has a built-in filtration system. A tank with a filter system will help keep your fish clean and healthy, which in turn will make it easier for them to thrive in your tank.

You’ll also want a fish that can live in a variety of water conditions, including saltwater, brackish, freshwater, salt-water and freshwater. The best way to find out what kind of fish you can keep is to ask your local fish store.
