Lps need to be fed for sure. they wouldnt have such a hugh feeding responce if it were not nessasary. Brain corals, duncans, candy canes, acan, are very high up on the feeding list. Torches, frogspawns, hammers, etc do not need to be feed as much.

From what I've been reading, open brains need feeding a few times a week, or they tend to die from attrition in 6 months to a year... I'll find the links in my history in a minute, but I'll share my experience first.

My open brain I've had for 2 months, has rejected anything other than finely chopped mysis. I tried larger pieces but they were regurgitated at night as was white shrimp and scallop (both finely chopped). My brain is 1.5 x 3 inch so size may make a difference... but consider that they are zooplankton feeders so they probably consume a lot of 'pod sized creatures. I haven't noticed any marked growth, but there has been no tissue recession and the color is as good as the day I bought it.

Now to find that article (if it was an article :mrgreen: ).

thanks for the useful info myka. i have had horriable luck in this tank with acans previously and the only colony i have left is tucked under a rock basically. well i think i can find somewhere to tuck this guy under and will be looking into setting the 20gal back up. any advice on lighting? think 4x24watt t5's will be to much?
