This is a discussion on Eastern Newts in Community Fish Tank? within the Newt and Salamander Help forums, part of the Beginner Newt, Salamander, Axolotl & Help Topics category; Are Eastern Newts compatible with community fish tanks with swordtails, Australian Rainbows and guppies? Thank you for any insights....
Many fishes are not suitable for typical community tanks. These fishes include:

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. Though not usually called community tanks, most  fit into this category too, using fish from places as diverse as the , , and western .

Any size aquarium can be used to set up a community tank, but remember the larger the tank the more choice in fish species and the larger amount of fish you can keep. A large aquarium also has the benefit of a more stable biology and fluctuations in water chemistry are slower to appear. For demonstration purposes we will be using the standard twenty gallon high tank (12 X 24 x 16) as the basis of our examples. Like all tanks, the community one will need filtration, heating, lighting and a cover as basic equipment. I will touch lightly on each here as much more detailed information can be found in the "Basics" and "Genesis" sections of the site.Diamond Tetra – The diamond tetra is native to Venezuela and it gets its name from the golden reflection bouncing off its scales. These fish grow to 2 ½ inches long or more and they prefer to be kept with 6 or more of their own species. Diamond tetras enjoy dimly lit planted tanks and soft water. They generally don’t have a problem getting along with most community fish.Though they are a common “beginner” fish that frequently end up in bowls, tiny tanks or just mixed in with other fish, goldfish are not suited for community tanks for a variety of reasons. This is a group of fish that have been neglected and misunderstood for decades. They require cold water with no heater and their high oxygen requirements make them incompatible with most other fish (and make the standard goldfish bowl completely out of the question!) They also grow quite large, so if you would like to keep goldfish, place them in an outdoor pond.Also known as an arrowhead or Mekong puffer, this is an ambush species of puffer. It is less active than other species, preferring to stay relatively still or even burrow under the sand until a meal wanders by. Because of this, it is not a good fish for community tanks—it is a hunter by nature. Pignose puffers can reach up to six inches in length.In terms of their water condition requirements, corydoras catfish prefer soft water between 5 and 10 dGH and it should be neutral in pH with a little bit of wiggle room either way. Though these are the ideal conditions for cory cats, they are fairly adaptable in terms of tank parameters – this is another factor that makes them a great choice for community tanks. Corydoras tend to live in shoals or schools with large numbers of other corydoras and this is how they prefer to be kept in the home aquarium.I had 6 Tiger Barbs and a Pleco in my 10 gal fish tank before the heater went out on me and I lost all Tiger Barbs. The Heater also went out on me in my 30 gal tank at the same time go figure, and I lost all fish in that tank…I cleaned both tanks out, replaces the heaters, filled them back up, and was able to save a Pleco, 1 Albino Corry Catfish, and 1 Spotted Corry Catfish which are in my 10 gal tank. I want to get a new Pleco and maybe a few more Algae fish for my 30 gal tank along with some other kinds of fish for this freshwater community tank but want bottom, middle, and top feeders…what do you suggest?
