There are several types of salamanders, and it´s important to know the habitat of the species you have, if it´s semi-aquatic, aquatic or terrarium and so on. And if it can live with another types of salamanders and so on. And if the their housing is secured against escape.     Semi-aquatic Is an aquarium which is with one dry part and the another part is with water, see picture below   Strictly aquatic fFor salamanders who lives in an aquatic environment. The aquarium is just like an ordinary fish tank with good filtration   Terrarium Is a terrarium with rocks, roots and so on and with a water dish to soak in.     Water Quality and Aeration The water quality is very important to the salamanders who lives in an aquarium or semi-aquarium. The aquarium should be filled with crystal-clear water that is filtered with at least one filter-systems. Some people use up to three filter systems one undergravel system, one outside power filter and a high-efficiency inside filter. Aeration is also very important, it prevents pollution and stagnation and increases the oxygen content of the water. Aeration can be provided with an air pump connected to an air-stone. This can come in handy when the outside temperatures gets higher. The salamanders prefer temperatures between 60 and 70 degrees F or 15,6 and 21,1 degrees C but check the habitat for your amphibia to get the correct temperatures.
