| i house my salty in a 6ft by 2ft by 2ft tank, and hes 80 cms, my freshies are in a 5 ft by 1 ft tank and they are only 25 cms, all are happy, they do all come out of the tank on a pretty much daily basis though.
temps, anything 27 or above in the water they get really active, so i try to keep it at about 26, and then bump it up for feeding, have a basking light, which hits temps of around 35 - 40.
i have fish in both tanks, they dont last long with the salty, and the freshies have had some fish in there for 3 weeks and still havent eaten them all(4 left of 10) its good because they eat whatever the crocs dont,
i think thats all you asked... need anymore info just ask |
