Hi everyone, I have had a single ADF in a 5 gallon tank for the past three years. He is doing wonderfully. About four weeks ago, my boyfriend and I set up a 20G long "Froghalla" and put 3 ADFs in it, with the intention of adding my original frog to the mix after two months. A few days ago, one of the frogs (the largest and thus least weak) turned up dead for no apparent reason. Yesterday I noticed one of the two remaining frogs acting very weak, being pushed around by my (incredibly low flow, barely moves the surface of the water) filter. This morning I found him dead. While the previous frog had looked normal (besides being dead, obviously!), this one had a very dark circle in the middle of his chest on the underside. I now have one remaining frog that is very small, and I'm worried about losing this one as well. I tested my water parameters and they are healthy (0/0/20). What are the symptoms of Chytrid besides the tattered sheds? I only saw one shed from one frog, and while it looked a bit questionable, it wasn't obviously in ribbons. Nevertheless, I'm wondering if this fungus could be responsible for the mysterious deaths. My other concern is that they are not/were not eating enough. I offered HBH pellets, which I've heard frogs can have trouble accepting. But, it was the largest frog that died first, and wouldn't they have been gonners much sooner if they hadn't been eating since I got them four weeks ago? I think if someone else posted this thread I would tell them that ADFs are often very sickly coming from the store and that these things happen with a weakened pool. (To clarify, the store where I got these 3 additional frogs was not the same I bought my original from. Admittedly, they came from a Petsmart-type store which has questionable stock and I don't fully trust the health of their animals. No offense, Petsmart.) But, I want other opinions. Also, what do I do now with the lone frog? How long until I can get more frogs (from a different store)?
