Recently, a Talbot's Damselfish I acquired from LiveAquaria died a few days after introduction to a QT Tank. I'm not sure what killed it but given that it's a damselfish, I'm wary that it might've been uronema but I never saw any of the trademark uronema burns on it before or after death. It just kinda got paler and eventually I found it on its side in the tank corner so maybe it was ammonia poisoning? The reason I'm worried is because I'm not sure if I need to sterilize my QT Tank for uronema since I know it can persist without a fish host. Worried also about how I'm going to deal with my snails and pistol shrimp since I wonder if they were exposed as well and I'm wondering if a prevantative metronidazole dosing period would be alright with the shrimp in particular since I know they're sensative.
