King of the AquariumDiscus are members of the Family Cichlidae and are sometimes referred to as "King of the Aquarium" because of their majestic beauty and regal colours. At least three species have been described, although debate continues over the validity of several assigned scientific names. Wild caught discus can be challenging to keep, due to their specialised water chemistry and dietary needs, however, most discus sold today are captive bred and are much easier to keep. That said, they are not for beginners for a variety of reasons. Through selective breeding, numerous colour varieties are available and more continue to be developed. For care and maintenance purposes, the information presented here can also be used for wild caught P. scalare and P. altum angelfish, as well as Uaru.
Natural Habitat for Discus
Discus are found in floodplain lakes and flooded forests of the lowland Amazon River basin and some of its tributaries, including the Rio Negro. These areas experience extreme changes in water level due to seasonal flooding. Discus tend to congregate near fallen trees, known as "galhadas", along the shore. They prefer quiet water and are rarely found in areas where there is strong current or wave action.
Discus Water Requirements
Discus prefer warm, soft, acidic water. pH should be between 6.0 and 7.0, with hardness between 1° and 4° dKH (18 to 70 ppm). Temperature should be kept between 82° and 86° F, although wild Heckel discus prefer water near 90° F.
Housing Requirements for Discus
Discus grow to be quite large and require an aquarium of 75 gallons (300l) or larger when full grown. Tall aquariums are best to accommodate their body shape. Water movement should be gentle, and décor should include large broadleaf plants and driftwood that is arranged vertically to simulate downed branches and trees. A few floating plants can also be added to provide shaded areas and cover. Substrate should be sand or fine to medium grade, smooth-surfaced gravel as discus like to forage along the bottom for food.
Discus Behaviour/Compatibility
Discus are generally calm, peaceful fish, but as cichlids, they can be aggressive toward one another, especially when attempting to pair off and spawn. Shy or submissive fish should be removed if they are unable to compete. Most serious hobbyists do not mix their discus with too many other species. Some suitable aquarium mates include cardinal tetras, neons, emperor and rummynose tetras as well as clown loaches and dwarf cichlids, such as rams and Apistogramma species. All of these fish tolerate the high temperatures and low pH/hardness required by discus.
What do Discus Eat?
In nature, discus eat a considerable amount of plant material and detritus, but also forage along the bottom looking for worms and small crustaceans. They are omnivores and will thrive on Pellets and flake along side a treat of frozen and live foods. Some hobbyists and breeders feed their discus beef heart, and while it is not harmful, it is certainly not a natural food for discus. For best results, rotate their diet daily and feed only what they can consume in 2 to 3 minutes, once or twice a day.
Discus Breeding Level – Difficult
Captive bred discus will pair up and spawn relatively easily, but young, inexperienced parents may eat their eggs the first few times, particularly if other fish are present. After hatching, the young feed on heavy body mucus secreted by the parents for a few days until they begin to free-swim. Parents will transfer the young back and forth several times a day.

Excellent product for dry mouth
Scent Name: Berry, Size: 100 Count
If you are having trouble with dry mouth, especially while sleeping, this is definitely the product for you. I have severe dry mouth and have tried multiple things including hard candy (yes, I know not very smart) as well as different biotin products, the mouthwash, the spray and the gel, which all do work, but do not last for very long. These stay in place open the corner of your mouth, last for hours and truly work. I highly recommend it if you are having a dry mouth issue

Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.

I Loved this book!!
Format: Hardcover
This was an excellent book. I used it for a Career Counseling course in Graduate School. I will use this book throughout the rest of my schooling. I will be able to use it as a study guide for my CPCE and NCE exam, as well as use it as a reference in my career as a school counselor. They have many useful appendices in the back of the book.
