Wrangy - still has all its tissue, except for the areas where I broke off branches. Most polyps are closed up, some are partially closed up. No changes in maintenance, 4 gallons weekly water change, no supplements, lights were changed in March, replaced w/same exact bulbs as before which were 7 months old (3 T5HOs at beginning of month and the other 3 at end of month).
Here are the changes that occurred and what has been added:
April 11th - Added new frags to tank
Acropora
Pink Sniper (A. selago)
Moonbean (A. yongei)
Limelight green slimer (A. yongei)
Purple rain
Stylophora
ORA Green
Cotton Candy
Tyree Rainbow
Echinophyllia
Red Firestone Chalice
Pink Mink Chalice
Over the following week slowly moved the new frags up from sand bed. On left side of tank, moved the large green monti digi from the rocks to the sand bed (it is on a flat piece of rock you can see in pic above) to allow current to newly placed acros higher up on the rocks, this monti does fine at lower light levels and is still doing well. Placed the firestone chalice at the base of the rock under blue monti digi. Ended up breaking off two large branches of the blue monti digi while digging into tank. Now it looks a little lop-sided. All seemed well in the tank. No issue w/Ca, Mg, KH levels, I've been monitoring to see if the extra sps would start to suck them up. Didn't think to monitor K or other trace elements, I figured the weekly water changes would cover those.
Then on April 25th I received these two corals from DianaKay.
Duncanopsammia - Giant Green Polyp Duncan (D. axifuga)
Briareum- Green Star Polyps (B. violacea/violaceum)
The gsp was a baseball sized mound and I placed in on the right side of tank as you can see in the photos above. After a couple of weeks it was large soft ball sized, it grew really fast. Around the weekend of May 10th I split the gsp into two and placed one in the center of the tank as you see in the photos above. The end of last week the blue monti digi was not extending many of its polyps. Last Friday I tested params, still fine on Mg, Ca & KH, did a 4 gallon water change and added a bag of new carbon to tank. Sunday I moved the gsp back to the right side of tank. Today I noticed the other three little blue monti digis (frags from the larger parent) are not extending polyps now as well.
All the new corals are still alive today. Only my older blue monti digi is not happy right now.
Now there were current changes by moving the large green monti, but I don't think that is the issue as these monti digis are pretty forgiving w/different current levels (I have some growing in size under overhangs w/little current). The addition of a predator may be the problem, but only one type of monti digi is being bothered and I have three different ones (blue, green and orange). Also been looking at night and not seeing nudi, pods, worms or eggs (yet). The placement of the chalice may be an issue, but it took a month for the blue to become unhappy if that was the case. Once the gsp was moved near the blue it became unhappy the following week. But, there also may be the potassium issue that I wasn't monitoring levels of so maybe that is creating complications? Remember I'm only changing out 4 gallons weekly, maybe this isn't enough to replenish the potassium?
So Thoughts?
