I know this is going to be a highly subjective topic, depending on species and such, but I'd like to know what size outworlds you guys use as a general rules... I've seen some very small, and I've seen some rather large... In another topic I see someone turning an 18 gallon aquarium into a 2 species vivarium.. which initially I thought was way too small... but I'm rather new to this, and am probably wrong...
I am founding 3 colonies currently, and none have outworlds currently... I have tons of dry aquariums around (ranging from 2.5 gallons up to 30 gallons), and plan to turn them into outworlds as needed... But, what's too much space vs too little? At what point do you determine you need to expand to a second outworld?
Anyway, just looking for everyone's preference and opinion on outworld size?
