Plecostomus, often called “plecos,” are a very popular fish and they make a wonderful addition to the freshwater aquarium. This may be true, but there are still some major drawbacks to keeping them. Common varieties can grow to be a foot long and they produce massive amounts of waste -- even smaller ones can still manufacture disproportionate levels of waste. You can basically double the bio-load of your community tank by adding one of these fish. In addition to that, some plecos don’t consume very much algae and may preferentially shred plants and driftwood. You should also keep in mind that while juvenile plecos are considered a community species, they often become aggressive as they grow.

It's a good idea to have in mind what kind of freshwater aquarium fish you want to keep in your freshwater aquarium setup before you purchase an aquarium. Some fish only grow to be an inch or two, whereas other types of tropical fish can grow 12 or 13 inches or more in length! Knowing what kind of fish you want will help you decide the size of the tank they will need. If this is your first time with an aquarium, it may be a good idea to start with a 10 or 20 gallon aquarium setup for now and stock it with some smaller and hardier species.Serpae tetra - A beautiful, small fish for the freshwater aquarium.

This could take a few weeks or more, depending on the plants and decorations in the tank. Although they are quite active, it does take a new shark a substantially longer time to become comfortable in its new environment than most other fish, and a pet owner may not see their shark for quite a long time. Once a shark has become comfortable it will claim a territory and generally stay in this area. If the tank is small, the fish may try to claim the entire aquarium and become aggressive or, at the least, start fin nipping. If you are planning to keep a shark in a smaller aquarium (under 55 gallons) it should be kept with fast swimming fish and fish without long fins.If you have decided that you are going to start with the small freshwater fish tank, you also need to decide whether it is going to be a heated fish tank or the cold water tank. Deciding on the type of tank will determine what kind of fish you can have because each fish has their requirements when it comes to water temperature. Just because they are all fish, it doesn’t mean that they can live in the same water. Some fish are okay with cold water while some can only live in warm water. Make sure to determine this factor before you can choose the right fish for small tanks.Rainbow fish are small, clorful, freshwater fish found in northern and eastern Austrailia. usually less than 5 inches in length, they live in a variety of freshwater habitats, including rivers, lakes, and swamps.
