I just finished my 125 gallon viv build and I want to get more frogs for it. Currently I have two D. tinc cobalts around the age of 6 months and of unknown sex. I wanted to get more of them, but I do not want to deal with female aggression and obviously I wouldn't be getting other morphs of the same species. Let's say that I have a group of six. Would that just be asking for trouble? If it would be a bad idea to get more of them, what other frogs are good to keep with these?
