Luohan fish is suitable for raising 1-3 pieces. It also depends on the size of the fish tank. They have a fierce personality. If the fish tank is too small and there are too many fish, they will easily compete for territory. Fighting will cause damage to their body surface. At this time, the Luohan fish will easily get sick and the wounds will rot. Secondly, they digest very quickly, metabolize quickly, and excrete a lot. If they are raised too much, the water quality will be polluted quickly, and the water quality will need to be changed frequently.

Methods for raising Luohan fish:

1. Water temperature. Luohan fish is a tropical fish, and the water temperature should be kept at 28-30 degrees when raised, and it needs to be constant. Fluctuating temperatures can easily lead to disease outbreaks in Luohan fish.

2. Water quality. Neutral water quality with a pH value of 6.8-7.5 is more suitable for Luohan fish to survive. If the water quality is too acidic, Luohan fish will easily burn its tail, which will affect its ornamental value.

3. Feeding. Luohan fry mainly eat red worms, and when they grow to more than six centimeters, they are fed frozen river shrimp. Sub-adult Luohan fish can start eating feed, and the supplementary food is mainly frozen river shrimp. Feed until the fish's belly bulges slightly each time.

4. Environment. The best size of the fish tank is about one meter, and the water level should not be lower than 40 centimeters. The bottom sand is paved with coral sand and volcanic rock, which is beneficial to the color development of Luohan fish. Luohan fish begins to develop color when it grows to around 8-10 cm. Proper lighting is crucial and can help the growth of Luohan fish.
