  • behavioral features – it will not be possible to keep slow and mobile individuals in one aquarium, since the latter will injure the first during movement, touching them;
  • tendency to spoil corals – some fish species will not allow creating a wonderful coral world in the aquarium, as it will nibble them.

The filtration and aeration system needs an external flow-through system. This will maximize the saturation of the water with oxygen and ensure sufficient flow. Also, with such cleaning, many beneficial bacteria will not be lost.

Lighting should be available according to the needs of the fish. For some, it needs to be very intense, while others are quieter in the presence of areas with shading. Depending on the inhabitants, a standard aquarium lamp is used, or a special one that works in a certain light spectrum.
