I have an 80 gallon mixed reef which is in series with a 20 gallon grow out tank and 55 gallon refugium which has been established for 20 years. This year I have had trouble introducing new fish. I introduced a small school of fire fish gobies (4) which all died by the next day. I assumed the fish had an issues, later introduced a wrasse (same deal), then 3 more fire fish, 1 made it. I managed to catch the wrasse and put him in the 20 gal. grow out tank just before he died, which is in the same water column and he is thriving. I added a ground to the 80 gal. show tank and increase water turnover to add more air. Still not working. I put the Wrasse I had in 20 gal tank back in the show tank and he tried to die within 4 hours, back in the grow out tank and fine now.
Temperature in Show tank is within 1 degree of grow out and chiller is set at 78 degrees.
Show tank has several fish which have been living there for years, Hippo Tang, Coral Beauty, Mandarin and Citron goby, etc. About 8 fish total and a fire shrimp.
Any ideas on what may be the problem adding fish?
Thanks for any help.
