11 Aquaristic beginner mistakes, which you should avoid in any case!

The common aquaristic beginner mistakes are as follow:

1. The size of the aquarium
   1. Too small aquariums are in need of care and cabinets are stocked with
   2. Large aquariums require space and insurance / Dominate rooms
   3. Dependence on desired stocking
   4. Inform before
2. The choice of the aquarium location
   1. Direct sunlight
   2. frequented room (otherwise shy animals)
   3. As a room divider?
   4. Room big enough?
3. Measure water values accurately and keep an eye on them
   1. Buy test set
   2. Check regularly
   3. Especially in the running-in phase
4. Running-in phase not considered
   1. Animals used too early and then perishing
   2. Algae infestation of the plants
5. The fish stocking => stocking density
   1. Fish should fit together
   2. Observe water values
   3. Pay attention to the size of the animals (also height for angelfish / discus)
   4. Size of the pool in relation to animals
   5. number of animals
   6. Type of pool (community pool, species pool)
   7. Pay attention to pelvic regions (bottom/middle/top)
6. The choice of plants
   1. Matching the stock (species tank?)
   2. avoid algae: fast growing
   3. Slow growing not good in running-in phase (algae)
   4. Required space
   5. Divide by pelvic region
7. The choice of decoration
   1. Should fit the type of pool (South America = roots, Asia = more stones)
   2. Decoration as hiding place and for spawning
   3. Too much decoration bad for floor level
   4. Consideration for the swimming behaviour of the animals
8. The choice of the floor ground
   1. How rough? (fine sand or coarse gravel?)
   2. Dependence on tank inhabitants (Corydoras goby in the sand)
   3. Some species prefer dark soil
   4. Dependence on the type of pool (species pools require a specific substrate)
9. The aquarium technique
   1. Light (also illumination time, fluorescent tube or LED, lumen, temperature?)
   2. Filter (internal, external filter, cleaning, with thermostat)
   3. Control heater
   4. Co2 plant
10. Partial water change
    1. Too rarely (pollutants are formed) or too often (withdraws nutrients)
    2. Tap water levels?
    3. Possibly osmosis water needed?
11. Fertilizing
    1. Fertilization essential for plant growth
    2. Especially if tap water is very clean (few nutrients)
    3. Depending on plant species (some need it (often fast growing and red), some do not (slow growing)

Conclusion: Planning and education

1. Absolutely meticulous planning
2. Inform about everything (read books and articles)
3. Procure test set and take into account the running-in phase
4. Plan the type of pool and then decide on the pool inhabitants and plants
5. Precise technology planning
