R.I.P., my favorite coral.
My hitchhiker Lobo decided to celebrate 20 years in my tanks by starting to die, and today I declared it completely gone. I'm not sure what happened. It previously had issues when nitrates and phosphates bottomed out, but that was not the case this time. The only alarming result of a Triton test was the iodine was about .24ppm which is quite high, but I don't know if that would kill corals. I did a couple water changes to bring that down some. I also tried a witch hazel bath, and ultimately I put it in a QT tank with antibiotics in case it was a bacterial infection.
Here is what it looked like back in January 2003. If you're thinking "that looks like a clam", that's because it is, but somewhere on the shell was a larva or tiny polyp of Lobo waiting to grow. The clam died after about a year, then the Lobo started becoming noticeable, looking like a mushroom at first.
Fast-forward to March 2011 and this is what it looked like. (I'm so mad at myself for not taking any pictures of it in its early stages.)
A year and a month later, it was really starting to take off.
Here it is March 5 of this year when it was really starting to go downhill. Look how wicked that skeleton is. I don't understand how evolution favored an animal that can rip itself to shreds so easily. Imagine if our bones were like that - every movement would be excruciating, plus we would probably bleed to death internally pretty quickly.
And here it is today (and a Scoly that also didn't make it).
Usually when you buy these big LPS corals, you get a lot of flesh with a small skeleton, but this one built up a pretty impressive skeleton over the years. You can see it has three distinct layers, where it had started dying in the past, but recovered and started over with a new layer. On the lower right you can see half of the clamshell that it's still attached to after all these years - the other half broke off when I moved.
This is so depressing, not only because of the loss of a cool coral, but having this one live so long and grow so large from almost "nothing" is the one thing that made me feel somewhat worthy as a reefer. Without it, I'm just another guy who kills corals.
