Hi All,
This should cover a few things that have not been touched on.
When you get a new frog (or frogs) the first thing you should do is quarantine. This should happen with every, single frog purchased with very little room for movement. These are some of the reasons:
If the frog/frogs are not adults you will want to monitor the food intake and wieght gain/loss.
You should get fecals done on every frog group you buy/trade for. Every frog group. If you have a tank of nice healthy Leucs the last thing you want to do is throw a Coccidia infested frog into your beautiful established tank. Fecals cost about $15. One fecal from an established tank will give you a very good idea of what parasites and potential problem are in the tank. If one frog has Coccidia, they all do.
Frogs of different size and age can potentially deprive each other of food or make new little ones a bit stressed. It sounds like you have kept a good eye on him and have recieved good advise to pull him from the tank.
Quarantine your new acquisitions and get fecals done on all of your tanks. There are a lot of potential parasites and other nasties that can/will/do infest tanks. Some of these parasites take years before you can actually notice an adverse effect. Sometimes that is too late.
