Q) In my aquarium, I sometimes find dead Cardina japonica in the morning.
What do you think is the cause?

A) Lack of oxygen is suspected unless that particular Cardina japonica was weak.
Aquatic plants perform photosynthesis during the day in the presence of light
and CO2, and respire during the night without carrying out any photosynthesis.
Haven’t you ever observed slightly clouded tank water or fast-moving gills of
fish in the morning? These symptoms are seen more frequently on a tank with
densely grown aquatic plants, and you need to pay extra attention if a large
amount of stem plants has grown all over the tank. You are advised to do
aeration using Lily Pipe or an air pump after turning off the aquarium
lighting. In addition, a decline in dissolved oxygen level during the night
leads to a shortage of oxygen in the filter and affects the microbiota. This
may create problems of imbalanced aquariums, which may cause algae to bloom.
