First of all, I do want to apologize for asking so many questions about my ADFs, I'm trying to do as much research as I can in order to ensure a good living situation for these little guys and figured this is a good place to get answers. As an update to my last post, the ADF who was floating ending up recovering from whatever problem he had been facing, and another one of my frogs very suddenly passed away (which at the time I had contributed to the heater possibly malfunctioning but now suspect dropsy given the bloat she had when I found her). Yesterday I introduced 2 new ADFs to the tank, and the 4 have been seeming to get along. Although, I feel like I'm running into a new problem after checking on them this morning. For starters, the one who was floating last time was having trouble staying on the gravel this morning, often floating up to the surface. He wasn't attempting to escape the tank, and was actually trying to stay on the ground, but it still gives me concern. And my second concern goes for one of my new ADFs. When I picked her up yesterday, I noticed that she had a little hunchback, and at the time I wasn't too worried because I had been told that deformities in ADFs are normal, but researching more into it made me a little more concerned, talking about calcium deficiencies and other stuff. I can attach a photo if needed, I just wanted to ask for some advice on possible courses of action if I need to take any. I'm looking into an exotic veterinarian that is situated a few towns over, although I'm unsure if they take ADFs. Thank you guys for helping me out.
