First of all, it is important to find out what technical equipment is needed for your pet. Aqua and humid terrariums require more maintenance. These are tropical plants and exotic animals.
As you will be trying to create a home-like piece of land, this requires a lot of effort and therefore constant care. You must always make sure that it is humid enough, that the sprinkler system, for example, or the heating mat, if needed, is in working order. After all, the terrarium should also provide a perfect little biotope for the creatures over a long period of time.
The overall technical effort in these systems is therefore much higher than in normal terrariums. You should be familiar with the factors involved. The maintenance effort should never be underestimated.
Suitable planting consists of plants growing under the water and out of the water or on the land.
