Heating 



Adequate heating is one of the more important 

 considerations in the equipping of an aquarium build- 

 ing. Certain peculiarities of aquarium buildings affect 

 the type and design of the heating systems. Higher 

 than normal temperatures are often required. Thus, a 

 building devoted primarily to tropical fishes should 

 be maintained at 80 degrees F. Ideal Hghting and ven- 

 tilation of an aquarium building is made possible by a 

 building design with an abnormal extent of outside 

 walls. Such a building even though well insulated will 

 have a high heat loss. This characteristic also makes it 

 difficult to maintain an even distribution of heat un- 

 less a special effort is made to avoid this problem at
