I have a 55g that has been established for over 1 year. I have had all the same inhabitants until recently. Original stock was 8 cories, 2 BN, 2 guppies, 4 ottos, & a pair of Bolivian Rams. Last Saturday I added 12 Rummy Nose Tetra's and as directed by Rivercats I used half dose of Paraguard, within 24 hours 2 died and 1 died the next day (3 rnt died within 48hrs). Well the last one that died, I did not remove it nor did I do a 50%PWC that I would normally do when I see a dead kiddo...the next morning I found 1 of my cory cat just sitting at the bottom right next to it. So I decided to take the rnt out and that's when I noticed something was wrong with that cory so I put him in my floating breeder box to watch him closely. Well about 1 hour later, dead. He did not have anything visible to see. I checked parameters, 0-0-10 or 20. So today I was doing a head count and noticed another cory doing the same thing AND I noticed my 2 inch albino bristle nose D.E.A.D.. Test parameters again, same as above, 0-0-10/20 and did a 75 PWC. I also took the filters apart, cleansed thoroughly, added new floss, rinsed biomax with new tank water, boiled all utensils, nets, etc...and letting them dry. So what did I do OR not do? What can I do to prevent further lose?
