Marinemom AC Members. Apr 8, 3, 0 0. Usually six is the minimum number for a school of schooling fish but keep in mind the bigger the school the more likely they are to school. That is the way you wouls see in the wild.
More room lets them school together and swim up and down the tank. Believe me, a large school swimming in a larger tank is so much prettier than a small group huddled in a tiny tank. The nitrogen cycle is so important to aquarium keeping.
Without it, our tanks would be filled with toxic soup and we would never be able to keep fish alive. These wastes sink to the bottom of the tank and start to break down. This is really bad because it creates ammonia NH3 , which is pretty darn toxic. Left unchecked, it would keep building up until it killed everything in the aquarium. There are several different kinds of beneficial bacteria.
One kind turns ammonia into nitrite NO2 Nitrite is just as toxic as ammonia. Another kind of beneficial bacteria turns the nitrite into nitrate NO This whole process of ammonia being processed into nitrite and nitrate is known as the nitrogen cycle. Nitrate is much less toxic than either ammonia or nitrite. It can take weeks, if not more, for beneficial bacteria to start growing in your tank. Getting these bacteria to colonize your filter so you can keep fish in the tank is called cycling the tank.
During this process, any fish in the tank are vulnerable to ammonia and nitrite poisoning. Pro Tip: Performing a fishless cycle is the best way to ensure your tank is fully cycled before you add fish.
This saves you money on replacing fish and also is more humane. They do not tolerate ammonia or nitrite well at all. They need nearly pristine water with no ammonia, no nitrite and low nitrates. The biggest thing to remember is to get a filter that is rated for the volume of your tank. That way, you should have enough capacity for the beneficial bacteria that process ammonia.
Neons come mostly from blackwater environments. Millions of leaves fall into the rivers and streams where they breaks down. The leaves put off tannic acid tannins that dye the water a dark brown.
Or you can include floating plants that will diffuse the light that hits the water and give the neons shady areas to retreat to.
Fry tanks are a bit different. Neon tetra eggs and fry are very sensitive to light. Neons are most definitely tropical fish. They love tall plants like Ludwigia repens, Brazilian pennywort also works as a floating plant , vallisneria, cabomba or Cryptocoryne wendtii.
Neons also like floating plants like frogbit, dwarf water lettuce or red river floaters. As an added bonus, live plants help to remove nitrates from your water. So if you want the cool castle that has bubbles and hidey caves, go ahead! Pro Tip: You can raise your own brine shrimp for cheap and always have live foods to supplement their diet.
Exceptions like the Buenos Aires tetra do better in cooler water. Do not forget to treat tap water with Aqueon Water Conditioner before refilling your tank! Most tetras can be kept in aquariums of 10 to 20 gallons, but larger tanks are easier to take care of and give them more room to swim. They do best in schools of 6 or more and will be less stressed and show their best colors in a well-decorated aquarium.
Dark substrates and decorations will help accent the bright colors of your tetras. Keep a secure lid on the aquarium to prevent them from jumping out if they feel scared or threatened. Provide mild but steady current. Most tetras are peaceful and get along well with similarly sized community fish, but there are a few exceptions. Serpae tetras, for example, can sometimes be nippy, especially when kept in insufficient numbers. Others, like Buenos Aires tetras get quite large and are very active, which may intimidate smaller, more timid fish.
Good tank mates for tetras include other tetra species, rasboras, small danios, peaceful barbs, appropriately sized rainbowfish and livebearers.
