So, I got an ADF and ACF the other day from a neighbor. They've been swimming in their own filth since she's had them, and I cleaned their bowl for the first time in forever earlier today, after I commandeered them. I just noticed that the ADF's limbs are quite red. Now, he's apparently been being fed red goldfish flakes every day, so I don't know if that's the problem, but I also know that there's a Red Leg Disease, and I'm worried. The ACF might be *vaguely* tinged red on his front legs, but that might just be because I'm paranoid. Any ideas on determining if they're really sick/treatment?
Thanks!
