Large freshwater community fish? - The Planted Tank Forum
Q: Have you been searching for a great large fish to add to your community tank
These gentle giants quickly grow to be 2 feet long and often live for up to a decade. While it is possible for some hobbyists with very large tanks to keep one or two tinfoil barbs, this type of arrangement is still not in the best interest of the animal. Barbs are highly social fishes and would prefer to be kept in shoals containing a minimum of 5 of the same species. With that in mind, no casual fish keeper can support that large of a bio-load in their community tank.
Due to their small size and peaceful demeanor, zebra danios are popular schooling fish for the community aquarium. Because this is an active schooling species, it is suggested that a school of at least six individuals be housed in a 20-gallon or larger aquarium. The aquarium should be aquascaped with plants and have plenty of light, but it is important that they have plenty of open space. A small school can be kept in an aquarium as small as 10 gallons, but this aquarium offers limited open space. In addition, if not kept in a school, some individuals may exhibit more aggression. If you plan on keeping any of the long-fin variants, do not keep them with fin-nipping tankmates (e.g., barbs, Buenos Aires tetras, etc.). Zebra danios are notorious jumpers, therefore make sure the aquarium is covered. They can jump through the smallest of holes associated with filters, electrical cords, etc., so block all holes.

Common community fish unsuitable for small aquaria
Having looked at some fish that make good choices for small tanks, let’s review some of the most widely traded and popular fish that would make bad choices for small tanks. In most cases sheer size is the issue: most anything above a couple of inches (5 cm) in length is likely to find a small aquarium too confining. Large fish make a lot of mess as well, and that will mean that maintaining good water quality will be much more difficult. Ensuring water chemistry stability will be difficult too. The following are fish that will require a tank at least 30 gallons (115 litres) in size, and in many cases significantly more. The usual way of stocking a community aquarium is to include fish and plant species from a wide geographic range that have similar wants and needs. Wants and needs? This means, make sure you community has fish that have the same pH hardness and temperament as the other inhabitants. Don't mix a Cichlid community with a small tetra community, unless you want a fat Cichlid community. It's pretty common sense stuff, but think before you buy. Water pH and hardness can come into play to some extent, but today most of the fish are bred in Florida or Singapore and they produce a fish that can adapt to the "average" fish tank. These tank bred fish are now more comfortable in our average tap water than they would be in their native ranges. The advantage of this is that the fish can now survive in all but the extremes of pH and hardness, which makes them ideal for our community. These can be just about anything you like from just being nice looking to a complete color scheme. You also want to have the fish inhabit different layers or regions of the tank. You want a fish selection that will include bottom, middle and top dwellers. These can consist of lively and sedate fish, nocturnal and diurnal, large and small, just about anything, remembering that they all must fit into the basic definition of "community,"
