Ben,

I like the salt water bath idea or maybe some other treatment used by the aquaponics guys to treat various ailments?

Shorty,

Aquarium temp is a pretty constant 68 F. I don't think it was ick as I saw no tiny specs on the fish and there was no rubbing on objects observed. Might have been some other parasite though.

Snrub,

The FHM were mixed small to medium size. The RRs were all smaller. In general, the smaller FHMs were the first to die.

Probably should have added this in my original post but I was focused on the larger 20 gallon test. I also had 4 small RRs in a 5.5 gallon tank and I added 4 small FHM to that tank as well. The FHM all died and so did 1 of the RRs. I did not monitor water quality in the 5.5.
