Saskia ~ For me for leos it is the length of the tank which makes it easy to achieve a thermal gradient. Never saying it is the only way. Too many inquiries to post ALL the ways. A 20 gallon LONG (30 length x 12.5 width x 12.5 heighth in inches) also gives leos more floor space to play. ;-)
Does that make 375 sq inches of floor space?
What is the recommended gradient for AFTs?
