These catfish and related species are terrible choices for community tanks, and maybe any tank at all. They can hit the one-foot mark at only a year and can quickly grow to their adult length of 4 feet. In the wild they have been rumored to reach 8 feet in length. If that doesn’t turn you away from them, consider that they prefer to eat fish (including their tank mates) and are sensitive to water quality.

Thanks for your answer above, is it good if I make a tank with the measurement 4x2x2 feet. Will this size be good for 6 angels or discus? I can't afford an external canister filter, instead of it if I use an internal power filter - only foam as filteration media, flow of 600/ltrs per hour. Will it cover the bio-load of six angel or discus fish? I can also place two filters of same power. But, can't afford external filter and it's expensive media. SOLUTION: The interior dimensions of a rectangular fish tank are 4 feet long, 3 feet wide, and 2 feet high

Again, the teacher should prompt students to think about what their tank would look like in real-life. A tank that is 40 feet long, 3 feet wide and 2 feet high would be very long, skinny and short. This tank would not be good for bigger fish, but it could be useful to watch something small that does not need a lot of space to move, such as a turtle. For two oscars, most aquarists agree that a 75 gallon tank is the absolute minimum. However, again, if you are buying a tank, I strongly recommend that you go larger. A 125 gal (476 liters, 6 feet by 18 inches by 22 inches) or larger tank will greatly increase the odds that your two oscars will get along, and will allow you to possibly have some other fish. You also have to remember, minimum size equals maximum effort. In the case of two adult Oscars in a 75 gallon tank, you need to plan on bi-weekly large water changes.If you already have a 55 gal tank, then fine, it will probably work for your oscar by himself. However, if you are buying a tank from scratch, I strongly recommend that you get a 75 gallon (286 liter, 4 feet by 18 inches, by 20 inches) or larger tank. This is for two reasons. First of all, a tank with a single fish in it is somewhat boring to most people. At some point, you will probably be tempted to get more fish. With a 75 gal (or larger) tank, this is a possibility. The second reason is because it is quite possible that you will end up with a larger than average oscar. Oscars can and do grow up to about 18 inches (45 cm). A 55 gallon tank is simply not big enough to house a fish of this size. If you have a 55 gal, and you end up with a monster like this, you will end up needing to buy another larger tank. It is cheaper and more eficient to just buy the bigger tank in advance. When you consider the total cost of a complete set-up, the increase in price of a 75 gal over a 55 gal is not that big of a deal.Common goldfish: 4 feet long and a volume of at least 30 gallons. If you plan to keep more than one goldfish in your tank then add an extra 12 gallons for each additional fish.With these rules explained, tanks are usually divided by lengths. The key lengths are 2, 3, 4, and 6 feet. Most tank manufacturers do not produce 5 foot length tanks and if you find one, you may have a hard time getting a stand. I recommend 3, 4, or 6 foot length tanks. 3 feet I feel is the best length for those on a budget or a beginner. 4 feet allows for a complete mixed reef setup and most lighting systems are designed for 4 foot aquariums. 6 feet in length is when you get to the territory of being able to house larger fish like tangs.
