Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.

(1) Wide range of activities Coral reef fish have become accustomed to a wide range of activities in the natural environment. The most unsuited to this is the sense of oppression in the aquarium. Sea fish have a wide range of activities, which is the biggest difference with freshwater fish.
(2) Familiar with the breeding ecology According to the different ecology of viscous eggs, floating eggs, etc., prepare the ovary (spawning and escorting field), and the eggs must have an attached ground. Stones or other substitutes must be placed in the aquarium.
(3) Light and water temperature Lighting is very important for the reproduction of fish. For example, clownfish are often hatched at dusk, and cannot be hatched without turning off the lights. Different fish require no lighting conditions, but at least the aquarium should be kept in direct sunlight for 2 hours to 3 hours per day. Water temperature is also important for reproduction. It is best to stay at 26 degrees Celsius to 28 degrees Celsius.
(4) Water quality Good salinity, pH, nitrite, dissolved oxygen, etc. must meet normal standards. Otherwise, even if the fish is not good, how can it breed?
(5) Preparation of juvenile fish feed Rotifers and brine shrimp are prepared. If you are still too large to eat, you must prepare algae. Algae cultivation and plankton cultivation are all essential to breeding sea fish.
Coral reef fish are difficult to distinguish between males and females, and many species also have degenerative properties, especially for long-headed fish and parrot fish, and even the case of the spiny butterfly fish. These fish, including butterfly fish, can live well in aquariums, but it is still difficult for them to raise the next generation.
From the experience of countries and our breeding of marine fish, we should pay attention to the following points:
