Hi RR,
Where are you located. The water here in VA changed within the last week. I can smell the clormaine the water comp is pumping into the system. What are you treating your WC water with before adding to your tank. No sense feeding them right now if they wont eat and leaving it in overnight is just not needed. Rule of thumb is if they dont eat within 15 mins vaccum it out. PBs are a bit harder to see the signs comming as they dont darken up as much as other strains. My first advice is dont bombard them with unneeded meds. I would start with the water first though and make sure you use something like prime that takes out cloramines. Hans is very good and his fish are awesome for sure. Did you feed any live foods? Ed
