Disasters and Lessons:
A compendium of tips, hints and idio(t)syncracies.
I am afraid I am going to be veering off track a bit from the "usual article" this month. I have been far too annoyed and saddened and mad at myself for still not having learned a couple of valuable lessons, even after all the years of keeping reefs. It occurred to me that perhaps my awful experiences this week can perhaps save some others from the same fate. Perhaps it will also let others see that those who write articles for really great web site aquarium magazines are not necessarily any less exempt from problems that brand new hobbyists. For some of you, this will be a "been there, done it, got the T-shirt," and for others it will be a "holy shnikes, I need to think about that." For me it was a ""I can't believe I am such a jackass to have done it again!"
My past week started off poorly, though inanely. I lost a baby clam (Tridacna maxima) I had purchased several months ago. He had once againfallen out of his "cup," again been picked up by my Golden Headed Sleeper Goby (Valencienna strigata) for use in building the "reinforcement wall" of his burrowed underwater fortress, and again been jostled, tossed, turned, and left in the dark for at least 24 hours before I could finally locate and extract the hapless clam . Unfortunately, this time he was no longer alive.
After all, this was about the ten thousandth time this had happened since I got him. I don't blame the poor guy for giving up He refused to attach to anything, and his growth had slowed and its mantle expansion has become progressively less over the past few weeks. It was a beautiful little Maxima, and my own negligence killed him.
Lesson #1 Make sure there is a proper location for clams (and all specimens, in general) before adding them to a tank after an impulse buy.
Lesson #2 Clams prefer to be sort of "burrowed in," and like to have a rough bottom to attach themselves. Such a location ensures their protection and welfare, allows for proper byssal attachment, and prevents them from falling. These stresses cause internal damage, tearing of byssal fibers and/or tissue trauma, failure of mantle expansion, loss of a stable and healthy environment, and increased susceptibility to disease, attack, or predation.
Lesson #3 If placing clams into little molded shapes, like old shells, etc., make sure this object is securely stable on the rockwork. Snails, especially Turbo and Trochus species, are very prone to dislodging unsecured clams and other specimens.
Lesson #4 Valencienna gobies and many other substrate burrowers and sifters may take all sorts of small objects from the reef to build a burrow, including coral fragments and clams, and may inadvertently bury them or injure them in the process. Even if "saved," repetitive trauma like this will eventually be quite deleterious.
Lesson #5 Dick Perrin, of Tropicorium, rightfully pointed out that baby clams really need to be undisturbed/dislodged for at least six months for good health and growth.
There are more lessons here, but these are the main ones. Please allow me to continue.
The saga continued when another clam was dislodged. Fortunately, this one was placed properly, had attached to his "cup", and the entire assemblage of clam and attachment had fallen mysteriously overnight. I (wrongfully) had *assumed* that this assemblage was glued to the rock work with the brittle but usually effective bond of cyanoacrylate adhesive, which I have found to be generally better for such applications, especially coral fragments, than the remarkably non-adhesive silly putty-like underwater epoxies that have a theoretical application for hundreds of uses, but in practice are good for maybe one or two. Of course, it took a flashlight and almost an hour of peering through the rockwork to discover it had fallen into the Murphy location...lodged deep inside the rockwork, where only a four foot long pencil thin arm broken (or at least dislocated and fractured) in several places would be required to rescue it. A miracle would also work...or complete disassembly of the rock. Well, I was feeling just a touch guilty for my negligence of the previous clam, and this one was nicer and bigger still. So what do I do? I reach for him! Carefully standing upside down on my head, using my curled toes like an owl attached to a branch to secure my position, I snaked in my arm, and tried to somehow reach the clam, while scaring my fish, being attacked remorselessly by a gold bar clownish (Premnas biaculeatus), and in general really causing myself great pain from the pressure of the tank top on my inner arm. I could just touch it with my fingertips...as if the accomplishment of mere tactile engagament was going to do any good. I certainly didn't have any small suckers on my fingertips to just pull it out. I should've pulled something else out (if you know what I mean), because like a sub species cretin, I remained determined to reach this clam with my big clumsy hands. Trying in a final attempt to rescue him by squeezing another inch out of my already distended and progressively numbed arm, I rotated my hand and jarred a rock. This happened to be a rock where my clownish harbored his pet Rose anemone (Entimacea quadricolor) ofwhich he is very proud (he just finished some additions and remodeling). He was engaged in the most annoying practice of alternately attacking me by ramming up against my hand and arm and taking little nips of my skin. While it is not painful, this type behavior is always surprising, and causes little flinches like the one that cause to all too soon to be described disaster.
Little Premnas had also been showing off for months, staking his claim to this healthy anemone (in the process of dividing, too, I might add) by vigorous back and forth waggling around the area. . No corals were nearby, since he would promptly butt all specimens with his head or grab them with his mouth and throw them off the rocks. Bastard swine. The anemone, of course, has a perfect location with his foot lodged securely in a hole near the rock/sand interface. Thus, the motion of the clownfish constantly stirred up a cloud of aragonite that covered all nearby rocks. This little behavior had undermined the rockwork and destabilized the entire side of the reef, not to mention the sifting and burrowing of the Valencienna. So, the slight jarring of a rock following a particular violent attack during the clam rescue caused an avalanche to end all avalanches (or would that be landslide...or even reef slide?). I called desperately for help, as I now had every limb of my body inside the tank holding up rocks and corals while using my teeth (I think) to anchor myself and prevent my total dismemberment.
