-Open Brain-
-Trachyphyllia geoffroyi-
The open brain is a Hard Coral.The care of this is relatively easy.They are generally semi aggresive towards of the tankmates so space should be given if not it can sting other corals.The open brain is considered by many as a medium maintence coral.They require moderate lighting and a moderate waterflow.They like to eat filter feeding invert food brine shrimp and micro-plankton a few times a week when it is open. Symbiotic algae zooxanthellae are hosted within this organism.If you get a healthy specimen from the beginning and give it moderate to high lighting and a moderate flow rate this is one of the most hardy specimens in the LPS group.Open Brain Coral has large polyps with a mantle that can be expanded more than three times the size of its skeleton during the day. Generally this is a nocturnal feeder, producing rows of tentacles to capture prey by the dark of night.Colors vary from with pink to reddish to tan to brownish to gray to greenish, blue.Being able to adapt to a wide range of lighting water rate and quality the Open brain is a good beginner or starter coral because this is the hardiest of all the hard corals/true stonys.Keep water quality high.The placement of this coral should be the bottom of the tank.
Hope to make this a sticky

A good choice of corals for those with established systems and adaquate water levels. I've kept a couple of T. geoffroyi for the past few years and both continue to thrive. The smaller of the 2 I keep was purchased at a discount due to tissue damage(it honestly was near death)...it now is in excellant condition and has nearly tripled in size. I try to direct feed each of mine at least once a week....preference is mysis/krill/silversides soaked in zoe/zoecon. My experience has been a moderate current and moderate lighting are adaquate but stable water levels are important for long term survival. Information indicates they do not tolerate stress well and sudden changes in water chemistry could induce problems. Also current is vital to remove debris from the tissue...and some fish that disturb the substrate could pose problems for keeping this coral.

I would try to stay away from using the "Watts-per-gallon" rule. For all we know, 4.5wts per gallon could be anything, from your standard home depot bulb, to your metal halide lighting. Watts-per-gallon is not an accurate way of measuring lighting intensity. PAR values also plays a very important role in lighting. It's not just the number of watts you have on the aquarium.

I have an open brain coral ( a green one ) and it is actually kinda strange. I will describe this as best i can and post a pic if i get a chance. The coral is perched just below the midline of my tank, and is at a slight (maybe 20 degree) angle. The part that is up top is nice and healthy looking, the other half however is not so. It is almost completely white. Could the inch or so difference between the two ends really make that much of a difference? I cant see ant skelton yet, and i keep checking for it. I tried feeding it at first, but now for the past couple weeks, i have not seen its feeders at all. i tried moving it, but there arent any real other spots in my tank to put it where it will be happy. Either unstable, or too much current, or not enough light. I am kinda lost with this one. any ideas would be great here.
My two clowns do pick at it on occasion, from when i used to feed it, they would try nd steal the food so they think that its hiding something. however they really don do it nearly as often anymore.
My water levels are as follows:
Ca 430-440
Alk 3.4-3.5 meq/l
pH 8.2
Salinity .025
Temp 79-80
trates 10 or less ( i dont have a real precise kit so its probably less)
Everything else as far as i can tell is normal. It has been this way for about two weeks now.

Unfortunately this one is now DOA. I woke up one morning and it had been half eaten by my Emerald Crab and it never recovered. I tried to catch the little@#%$ for weeks. I finally had the last laugh. When I was changing my 55 to a SPS tank I pulled a bunch of rock out and the emerald was attached to one (I didn't know it). Unknown to me he jumped off the table I had the LR on and was walking on the carpet. I steped back to see how the replacement of my rock looked and crunch - Justice was served!! (albeit unintentionally of course)!
