Halfmoon is probably the most fish need care. Remember that the long tail bettas like halfmoon fish are domesticated and may not be able to survive in the wild. This means is halfmoon need the space and the more care compared to short tail betta.
90% of diseases have the same cause: poor water quality. The secret lies in Halfmoon need space as large as possible and change the water constantly. Unfortunately, the best way to replace 100 percent of water a day is the way that most of us do not have time to do! If you change the water, some bacteria still fish left in the bottle. They can cause disease in fish. If you can not change the water every day, change the water every 3 days also, depending on the size of your fish jar. Ideally, every day should suck the dirt from the bottom (and then pour water into the bottle). Use water disinfection chlorine (or to wreak). Necessarily eliminate all compounds containing chlorine, which does not exist outside of the natural environment. Should also check and adjust the pH to make sure it reaches the level needed for fish. There are many drugs that increase or decrease the pH outside the market.
Plants is a good option. As in the wild, trees phosphate in water consumption and improve water quality when you only replace the part. Although phosphate is not toxic to fish, but it stimulates algae growth, I recommend that you grow Java fern to consume the phosphate in the water. Java fern is often accompanied with driftwood. Please remove plants from the woods before being planted in the lake for fishing driftwood often with sharp edges torn fins. Plants also consume nitrate. Please allocate sufficient space next to plants for your fish to swim. Pruning when necessary to ensure that this space is balanced. Let’s grow the same crops in the new tank when you get farmed out separately. If you buy fish from other breeders, ask them about the conditions raised there and try to re-establish conditions so that as closely as possible. This can be very important! The red line and red (non-red) are particularly sensitive to any change of the chemical composition of water.
Feeding the appropriate food. Feeding a variety of foods and dry foods contain many vitamins. Personally I like to eat frozen fish (fresh and dry food but do not contain pathogens such as fresh food). However, you should let the fish eat little but often (enough to feed all of five minutes). Otherwise, excess food will decay and cause high ammonia concentrations.
Flaring fish every day by soi glass or embankments it with other fish. But do not let it see other fish because it will often be large. If you fish the bottle together, should cover it (ie prevent this bottle with another bottle with a cardboard or anything else) or to so many jars together to fish regularly island through the island between the others each other and do not open the bottle. Note that fish have fins loud and long, so if it spread up too tight and too long, the fins may be cut, so it’s best to limit flaring of the time they are only about 1 hour per day.
It is more work, but the great beauty of halfmoon when they flaring worthy of this service.
