In the past week I have lost two of my dart frogs very unexpectedly. I have had one of them for about six months and the other for about two months. They were in seperate tanks and came from different places. The tinc was in a tank with one other tinc and the azures was in a tank with one other azures, two auratus, and two "singing" dart frogs. The only things that they shared were fruit flies and their water came from the same RO unit. Other than a dominance issue, what could be the problem here??
