I cannot say enough good things about these fish. They always come in great and I've never seen them with bacterial infections. Wild discus have a reputation of being prone to disease but I have the exact opposite experience. Domestically raised, line bred fish from Asia or even local breeders can often succumb to bacterial infections out of nowhere and once it starts there is very little hope for treating them. That is why i am proud to offer these fish. They are quarantined and eating medicated flake food to ensure good transit experiences for you and the fish.
