D/T undoubted residual Cryptobia chronic infection in the 210G discus tank and the introduction of a new healthy discus from NADA meeting, I will treat the current discus stock/tank with Dimetridazole to help decrease the risk of the new fish being infected. Previous introductions to this tank have resulted in 75% mortality with confirmed Cryptobia. Interestingly, the Raffelesia discus have been resistant to any signs of Cryptobia infection.
210gallons + 50 gallon sump= about 1000L
dimetridazole 80mg/L=> 80gm
This is difficult to sustain at this volume, but capturing discus in this planted tank will be difficult. I'm considering options.
