Hi all, i am new here, i have a 120gallon tank that has been running for about 8 months. i have 1 bicolor angel, 1 bluegreen chromis, 1 fire goby, 1 diamond watchman goby, 1 sixline wrasse, 1 pair of false clowns, (all are at least 4 months old, ) 1 electric blue hermit, some turbo snails as well as some zoas, green star polyps, 1 toadstool leather, some hammers touch and bubble corals. my nirate is 0, po4 is probably at 0.1. however my corals are opening up properly and the fishes are feeding normally. however i can't seem to add anymore new fishes. 2months back i tried to add 1 pair of flame anthias both did not eat and 1 died 5 days later, the 2nd one lasted 2 weeks. i tried to add 1 lawnmower blenny 3 weeks back but it died last week, 1 coris wrasse a few days back and he died the next day. i use the drip acclimation method on all my new fishes for at least 1 hour. anyone has this problem too? i cant seem to figure where or what has gone wrong.
