hey all, i just bought 3 emp scorps today, first ones ever for me... at the moment, i have them all together in a 10 gal terrarium, 3 hides, a water dish, and a water bowl. i have anywhere from 3-5 inches of substrate (3 on the warm side, 5 on the cool). the cool side has 2 of the hides, the warm has 1 and a 3x5 mat of moss. water dish is in the middle.... there is a bit of room for them to borrow.... the only thing is, the 10 gal tank has a fitting lid... i have a 20 gal which isnt being used atm, but it only has an aquarium lid. should i switch them into the 20 gal so they have more room? any advice would be great. thanks.
