Terry I enjoyed your editorial re: angelfish in reef tanks. I have had a Koran and a flame angelfish in my 170 reef tank for several years. Which corals are displayed in this tank has been a joint decision between myself and the Koran with the Koran always having final say and the Koran has set the feeding schedule which presently is at 4+ times a day in an unskimmed sumpless tank. Recently the Koran trimmed the gowing edge, poyps and skelaton, all the way around an orange Montipora capicicornus (an established coral in the tank) and then proceeded to snap off the distal 1/8 to 1/4 inch of a M diditata (newly moved to this tank) I have responded and upped the volumue of food that I'm feeding and the coral eating has at least temporalily stopped. All of my tangs and angels are very plump and heavy. I maintain a contious supply of live Macro algae for grazzing and rotate macro speicies as they get near the end of their supply.

Do you have any suggestions as to how to satiate this Koran as it switches to adult coloration pattern without totally overfeeding the tank??

About 18 months ago I net fed the tank for about 6 wks and the Koran would eat out of the net but I misssed when I finally tried to catch it and it has been very skiddish ever since, at this time it is nearly impossible to try to catch it and besides I really kind of like the fish and would like to be able to keep it in my reef and be able to keep all/or most of my corals.

bgdiving,

You have to get that angelfish out of your tank; it has developed a taste for too many sessile critters. Leaving the net in the tank for a week or so may help the angelfish forget about it, and you can try to find where it sleeps at night and if accessible shine a bright light into its eyes when the lights are out, then net it, or push it into a clear container.

:( Terry that's not hte answere I wanted to hear. I was hoping for the magic food :wink: that would satisfy him and meet his needs to graze on things. Unfortantly I've probably know for about 18 months that he needs to come out. He'll be real hard to get out, he's the last to come up to feed and the first to flee with any motion. He's real skidish when people are near the tank. It'll agressively take food from the tangs when they get it lower in the tank. The tank is 30 inches deep and he sleeps under a huge stack of rocks all the way down at the sand, well back from the edges.

Great article Terry! I also have a juvenile P. navarchus in my reef and it behaves exactly as you described. I had to remove my T. geoffroyi, and my Favia sp. corals. Everything else, so far so good. Thank you for the informative and accurate article.

Regards,
Kevin

Do captive raised angles dietary habits and or needs shift as they mature in a reef tank setting? and if so what would be the typical change in eating habits. The Koran is in my primary display tank in the house but since I have several other reef tanks in the garage, I do not feel compelled to keep any particular coral that may be incompatable in THIS tank.

I think you're fairly safe with SPS corals, especially Acroporas, but one can never predict with 100% accuracy what a particular fish will decide to eat.

sometimes the only answer is to remove rockwork, while yes it sucks worse than anything.... the angel eating your corals is gonna really piss you off after a while.
