I have a 100g tank in a print shop (4 years old) with a few softies and 120lb of live rock. We have a trickle filter, a very good venturi skimmer (Deltec 600 which replaced a far inferior Turboflotor - best skimmer money can buy IMHO)
i used to look after it myself , but a guy from the LFS looks after it now and over a perios of about 6 months he put in 7 anthias. We also have 5 fat green chromis, a yellow tang, a Hippo, a Firefish, a lawnmower Blennie, a tank bred Percula. All but the Hippos, the anthias and tang are recent additions.
The tank is not fed of Saturdays or Sundays because we're closed then. Chistmas did not pose a problem either (fed 5 times in 10 days)
We have had no problems with the Anthias, although we lost 2 gobies soon after they were put in. I was very surprised to read Fenner to find how he says difficult Anthias are.
To me they seem no more difficult than green Chromis. Perhaps the ones sourced in the UK are better than those in the US.
