I have two Magnificas in my tank. One was from a local, who had it a year, but under insufficient LED's as well as low flow. This nem was on the very top of the front pane when I got it. In my tank, it enjoys the added flow, but I have slowly acclimated to my light, which is a dual 400W Sfiligoi, where the bulbs are side to side, so basically 800W. I currently have this nem high, but on the outer edges of the tank, where the PAR is 600. This nem has short stubby tentacles.
You can't see it in the pic, but the tips used to have a dark spot on each one. Now the tips are getting yellow, with the dark spot in the center of the tip.
My other Mag, was a replacement for a DOA SPS colony. They happened to receive a half dozen of these, and they held them for a few weeks to make sure they would send the healthiest one. This nem was placed on a rock that I could move and acclimate to my light. Because this one never showed any signs of stress from my light, it currently sits directly under the 800W, where the PAR is over 1300 just above the oral disc. This nem has long thinner tentacles...
Both these nems are in the same tank. Both have been able to capture food and bring it to their mouths in 15 minutes or less, without shutting off my pumps. Both securely footed within a few minutes of placing them in the tank.
One was shipped, looked horrible when it arrived, was temp acclimated and dropped into my tank, where it inflated, and hasn't deflated once. The other came from a local who had a tank with insufficient flow and lighting. That nem has inflated and deflated once, and that was early on, and I felt I stressed it by having it too close to my light. Since I moved the rock to the bottom, and slowly brought it to the surface, the nem hasn't deflated.
My question is why do these nems have different types of tentacles? Is the shape of their tentacles a sign that they are stressed at all? At first I thought it was lighting, but the one with the longer tentacles is directly under 800W. While the short tentacled one is in lower lighting. It can't be flow, because the short tentacled one was subjected to the most flow while I light acclimate it. Both have excellent feeding response, having no trouble grabbing and moving their food to their mouths with both a MP60 and MP40 at 100%.
Here is how they sit currently in the tank.
My parameters are pretty solid, with Ca 420 Alk 9.0 Mag 1350 PO4 0 Nitrates, and Nitrites 0, tank has been set up for close to 3 years. Been planning to get magnificas for over a year, even removing SPS to make room. The tank was algae free, until I got some dry rock that was perfect to have the nems foot to. Instead of having them move, and possibly killing my sps or themselves, I chose to have rocks that I could move for their benefit, such as was the case with the light stressed nem.
