Hey liz!! Can´t PM you, quick question, with Leos the rule of thumb is 20 gallon long tank for a single animal, however, 20 gallons measures capacity, and since leos can´t climb I was wondering how many square inches of floor space did an ideal tank for a leo had ...?? I know I am no newbie to this but I acquired 3 AFT receintly and I bought new tanks and they seemed to be perfect size for them (accordingly to the measures and advice given here in the AFT subforum) and they are bigger than my leos and my leos have more space but I believe I have them in 14 gallon tanks..... am I making any sense???? I achieve temp gradients just fine in 14 gallon tanks (maybe the environmental temps helpe me a bit)... to sume up, how many square inches of floor space would be ideal for a single leo???
