Hi, sorry about this... As Tony said, you will need to start a Lamasil treatment asap for your frogs, all of them. I will stress out that everything they came in contact with need to be sterilized as Tony described: the tank, the bath container after each rinse, etc...
If you were using any sort of tools, either to clean the substrate or pick up crickets, likewise.
As for the Lamasil AT, I've recently treated a small group of frogs as a prevention using Lamasil. Here are a few pointers, though, to make sure everything is done correctly:
1. The treatment "bath" was usually not deep - basically enough that the stomach and base of the legs/hips would be in it, but not up above the chest which could be a drowning risk.
2. Size of the container is also important, to try and make sure they are in contact with the solution, and not spend most of their soak climbing up the sides not in contact with it.
3. Make sure it's properly diluted. A friend had a frog lose an eye after a treatment. Water level as stated above shouldn't be too deep to prevent contact with the eyes.
4. One thing to think about with the treatment of your White's maybe giving them a really good rinse in plain water after the treatment (particularly if they get it in their eyes) and before they go back in the tank to rinse off any extra medication. There may be some alcohol in the Lamisil that is irritating the eye and causing the issue. Rinsing would help, but also letting the alcohol evaporate.
5. As Tony mentioned, try and keep the stress level of your frog to a minimal. It was reported that a high stress from treating for Chytrid may have driven the bacterial infection out of control.
Good luck!
