Ich is a highly dangerous disease; kill thousand of perfectly good fish. Luckly we have a cure... raise the heat up ( 85 degrees is fine in a tropical tank, but for bettas, aquarium salt will be fin; you can get at your local petstore.) Then go to the petstore and ask for the chemical "quinine hydrochloride"

Wiki clip Endlers livebearers

Endler's livebearers are hardy and undemanding in the aquarium, though they prefer hard, warm water. The warmer the water, the faster they will grow; however, this also seems to shorten their lifespans. They can be kept at 18–29°C (64–84°F), but their optimum temperature seems to be 24–27°C (75-81°F). This is slightly higher than their guppy cousins, which prefer 23–25°C (73-77°F). They do best if kept in tanks with plants (preferably live plants, but fake will do) to give them hiding places and (although they may be less likely than guppies to eat their own young) give the fry a better chance at survival. Some of them are determinedly suicidal jumpers, so a cover on the tank is a must.

Guppy

The guppy is a wonderful fish to keep. Their Latin name is Poecilia reticulata. It is a small fish, growing to be 3in ,and they are native to Brazil and Venezuela. When guppies are 3 to 4 months old, they will start to breed. The male has a genital tube, which is bent forward which he uses to inject sperm into the female guppy. When this is done the female genitals will begin to enlarge themselves. She will then release the babies.

The guppy is rather hardy and likes temperatures between 70 and 80, a 5-11 gallon tank, and a water pH of 7. If your guppy is well cared for, it will have lots of color pigments.

Bloody Jack D

The Jack Dempsey (Rocio octofasciata  ) is a Stupor Mundi, or "Wonder of the World." This wonder is a native fish to Honduras and Mexico in their slow moving, murky water, filled with small tropical fish, worms, insects, and algae, favorites of the Jack Dempsey.

This fish lives in a tropical environment with water that is 60 to 90 degrees, that has a pH of 5 to 7, in which it grows to be 10in (25cm.)

This fish is hardy, requiring the most basic need, almost meeting those of a betta! They are a personal favorite of mine

Despite how wonderful this Stupor Mundi, this wonder may seem, it is very aggressive. Someone quotes the Jack Dempsey as a "assassin" that "uses piranhas as toothpicks, "after he put this fish in a friends tank with $4000 dollars worth of fish, and saw a lot missing fish and a plump, happy Jack Dempsey in the tank as soon as he came back. If you wish to keep this fish, make plenty of caves and plants for the weaker ones to hide in.

Over all I recommend these fish.

The Betta or King of the Asian Ponds

Bettas grow to about 3 inches. They are known for their brilliant colors, and long fins, but in the wild, they have much shorter fins.

If you wish to keep this fish  do not keep them in  your community tank.

. There are lots of kinds of bettas here are a few. The Crowntail Betta is known for its complex fins, that look like a crown. Besides the fact that it tail looks like a crown, it's the same as any other betta. There is a similar betta called the Halfmoon. The  Halfmoon gets its name because of it 180 degree back fin. It is prone to tail biting and fin damage. They are hard to breed. There is a more elaborate Halfmoon called a Rosetail. Rosetails can be really elaborate or just moderate. It has three unpaired fins, and extra branching.

 The most common betta is the Veiltail. It gets its name because the tail looks like a brides veil.

The plakat  is the most ferocious of all the B. splendens.  Also known as the short finned fighter. It is used in fish fights. The Double Tail has two back tails. They also have larger fins than other bettas. The Dragonscale is a mutation of a plakat.

Bettas originated in Thailand, Cambodia , and Indochina where they have two types of seasons, dry and rainy. In dry season, bettas live in puddles. In rainy season they live in ponds, rice paddies, and sometimes in flooded streets. Their usual diet consists of mosquito larvae, algae, leaves, and worms.
