Just one more thing, I took the ranchus to the vet. They had hemorrhagic septicemia and none of the pet store antibiotics were working. I tried tetracyclene, triple sulfa and tetra lifeguard. It turns out that the antibiotics from the store only stop the bacteria from reproducing. It does not kill the bacteria. I did not want the bacteria to turn into dropsy and cause the ranchus' kidneys to shut down, so i took them too the vet. They got 5 ceftazidime shots each. Ceftazidime is a prescription antibiotic that kills the bacteria.
