this is important because honestly they prob. would have picked each other off in time in your tank, ESP. in your size tank for that matter. ive never kept a school of them, though i think it would be nice, ive heard thats what they do. pick out the weaker chromi until your down to 1.
I guess I really had the wrong idea when I thought chromis were the peaceful alternative to damsels. I seem to recall reading many times that that was the case. For instance, Drs. Foster Smith goes on about chromis as if they were the most peaceful fish in the ocean. Saltwater Aquarium Fish for Marine Aquariums: Blue/Green Reef Chromis
Have you known somebody who's chromis picked each other off or read first hand accounts of it somewhere?
I personally use the interchangable pad that comes with the Whisper filters. The one that is a mesh bag full of carbon...
I change 50% of the water once I transfer a fish from the Q to the Display.
Thanks, Jeff. The quarantine tank's HOB filter came with a mesh bag/pad, but I removed it since it contained carbon and had read that the carbon would render the PraziPro I added to the tank as a preventative measure ineffective.
Something I don't think has been mentioned here but is worth noting. Many healthy systems do infact have some ich parasites living within the system but the fish never show symptoms because they are healthy enough to fight off the infection themselves.
I've heard something similar (or the same), that most fish actually have ich all the time but it doesn't manifest/become an issue until their immune systems are compromised. Do you think it's possible to rid a system of ich altogether?
That said I agree with the more experienced folks that you should leave the tank as is and continue to carefully monitor your levels. In the future when looking for fish if you want some that will shoals and are less likely to kill each other off take a look at Cardinal fish in the Apogon genus.
I don't plan on adding any fish to the display tank for 4 - 6 weeks. I may add a few more inverts in the meantime to keep things somewhat interesting, though. Thanks for the idea about cardinals. I'll keep an eye out for them when the time comes to add fish to the tank again.
