Well, I am a freshwater guy as of now..But I want to try out saltwater. I was thinking of starting with a 2.5gallon aquarium with live sand, softies and maybe a fish if there are any that can be in a 2.5g. What are the best hoods/lights, filters, heaters for a 2.5 gallon? And also how do you cycle a 2.5gallon aquarium? Any help would be appreciated!
