メダカが卵を産まない原因と産卵を再開させる4つの対策

This article explains the causes and solutions when medaka fish suddenly stop laying eggs or their egg production decreases. It summarizes specific methods you can try in order, including water changes, reviewing their diet, using spawning stimulants, and changing pairs. There are four main reasons why medaka stop laying eggs: physiological spawning cycle, cessation due to environment or stress, age/long-fin breeding influence, and disease. Since the appropriate countermeasure differs depending on the cause, it's important to first carefully observe the fish's condition. Basic countermeasures include stimulating the fish by completely changing the water and supplementing nutrients with daphnia or spawning-specific food. If these don't improve the situation, using spawning stimulants such as Tetra Vital or PSB (photosynthetic bacteria), and even changing pairs, can be effective. Try each countermeasure one by one, without rushing, while checking the cause.
