Maintenance and Care
01. Cleaning the Aquarium
If there are stains on the surface of the tank, use a soft cloth dipped in a small amount of
clean water to wipe them off.
If stains or algae appear on the tank wall during use, please use a professional algae scraper
(purchased separately) or biological algaeremover (both sold separately) for cleaning.
Note: Do not use gasoline, kerosene, ammonia, bleach, or other corrosive, volatile chemical
solvents for cleaning, as they will seriously damage the appearance and internal structure of
the tank. Do not directly rinse the cover (containing electronic components) with tap water.
Ensure that the aquarium is powered off and the power adapter is unplugged during
cleaning to avoid electric shock or serious malfunctions caused by water entering the
electronic components.
It is recommended to clean the physical filter module once a month or replace it every three

Fish Care Tips
For beginners, it's recommended to raise fish such as zebrafish, danios, guppies, molly fish,
platies, pearl fish, and swordtails, which are hardier species more tolerant of environmental
conditions.
Your pet store’s fish specialist can help with any questions on maintaining a proper mix of
fish and environmental elements.
2.
Cleaning the Aquarium

02. How many fish are suitable for the tank?
03. Proper Tank Setup
11
The maximum capacity of the Jengu Aquarium is 20 liters. It's suggested to keep 10-15 adult
fish with a size of 5-6 cm, 6-9 adult fish with a size of 6-8 cm,or 3-5 adult fish with a size of
8-12 cm.
7. Remove the turbine and rinse it with clean water.
3.
Filling the Tank with Water
It is recommended to use a small-capacity independent container and pour water slowly
multiple times.
4.
Introducing the Fish
When introducing new fish to the tank, they need to be acclimated to the water temperature
and conditions to prevent stress and potential death.
• Temperature acclimation: Place the fish bag in the tank and let it sit for 30 minutes.
• Water acclimation: After temperature acclimation, transfer some water from the tank to the
fish bag.
04. Handy Tips
1.In the following special situations, it's recommended to change the water promptly:
12
2.Feeding Frequency: It is recommended to feed 2-3 times per week, with each feeding session
lasting about 3 minutes. Feeding sparingly but frequently is advised; avoid overfeeding.
Tips: Adjust the frequency of water changes based on actual conditions. lf the temperature is
too high, more frequent water changes are advised. When changing water, complete it over
3 days, replacing one-third of the water each day.
• Dead fish should always be promptly removed, as their bodies decompose, causing the
water to become fouled.
• Multiple fish deaths that occur within a 5 day period.
• A large amount of algae grows on the tank walls within 3-5 days.
• There is a large amount of foam or parasites floating in the tank.
For example: for 15 zebrafish measuring 3-5cm, feed powdered food every other day (rotate
the feeder once).
lmportant for beginners: Pay attention to the frequency and quantity of feeding.Overfeeding
can lead to fish bloating and uneaten food polluting the water.
Note: Do not use fish food, live food, or wet food with a diameter larger than 2mm to prevent
clogging of the feeding port.
3.The feeder has two settings, which can be adjusted based on the amount of food consumed
by the fish in the tank.
4.Avoid keeping the light on for extended periods or placing the tank in direct sunlight to
prevent algae blooms and potential fish deaths due to the impact on the filtration system.
