I assumed as much for the coloring, I just wanted to be sure that I shouldn't be expecting that brighter green unless they're active. They're not BROWN, more of just a really dark foresty-green, but they get brighter at night time as mentioned. As for the dechlorinator, I'm not wondering about the film or the bubbly water really (those were just notes to show the difference between the topfin brand and the flukers+aloe). What I'm really wondering there is if the aloe in the dechlorinator is ok for my little guys. I know I've heard that additives can be harmful to frogs (i.e. the pain reliever in Neosporin), so I wanted to be sure that it's safe to continue using this. Thank you for the feedback though .
