Unfortunately, BC does not protect against a chytrid re-infection. It treats it once, like antibiotics for a strep infection. If you catch strep again later, you need antibiotics all over again. Since you have chytrid in the house, and potentially in your water supply, you will probably never be able to save your toads from the disease, unless you constantly treat them with BC day in and day out. Unless you physically isolate them from the ACFs, as in other sides of the house, and go to such extremes as washing your hands and arms with straight ethanol alcohol after playing in either tank, you will reinfect the toads again.

As for your bullfrogs, since they've been in with the ACFs, they can be assumed as having chytrid in their mouths, which will spread to the rest of their bodies as they metamorphose and begin to develop keratin in their skin all over. So you now have even more chytrid-infected animals that will not die from the disease, and as of yet, we have no approved treatment for. Please be aware of this, and what it means for their long-term care. Plus, it limits what other amphibian animals you can bring into your household now.

As for "researching tankmates for your ACFs", we've repeatedly advised that we recommend putting no other animals with them (for good, experienced, documented reasons, previously highlighted in this thread). We are happy your plecos and tadpoles are working out with your ACFs, however, our research and collective knowledge suggests this type of arrangement does not work out. Therefore, it is not something that we recommend. I am going to re-iterate for any visitors who come looking for chytrid information, or ACF tankmate information. We do not advocate mixing ACFs with any other animals besides other similarly-sized ACFs for reasons of the risk or injury to the frogs, predation, and the risk of chytrid fungus spreading. But we also realize that you are free to do whatever you want, and all we can do is merely educate. It's up to you what you choose to do with the information.
