I have been doing reef tanks since January, so I am fairly new, but I keep losing Green Chromis. I am wondering if they are a weak species or if I am doing something wrong. I have 3 original that survive but all new ones that I add die off. 0 Ammonia 0 Nitrite 0 Nitrate 0 Phos 8.2PH 11dkH 1.023SG
Unfortunately from my experience that is normal with those fish. I know a few reefers with larger tanks that like to have a school of around 10 and they say they usually have to replace 3-4 a month due to deaths. I guess they are just a weak species or somehow are stealth killers and take out the weakest at night. I know my neighbor who had a 75G had just 2 of them and they lived for about 5 years and his tank was definately not what I would consider well maintained by any stretch of the imagination. So not sure what to make of it, maybe you just have to get lucky or maybe only 1 out of 10 actually make it in a shipment.
