Well, one of my relatively new frags, an Acropora "millepora" (could be one or two other species) began showing bulging, white polyps. After observing for a bit longer, it began literally popping eggs out. The first thing that goes through my mind is, "okay, this doesn't usually happen unless the corals are stressed." So basically, I have been racking my mind to find out what the deal is. Nothing has been changed on my part, all tests come out like usual, temps and salinity in range, etc. All powerheads are working properly, etc. All other corals and animals look great. I also noticed that we are very close to a full moon (or may have already had one or something--I don't keep track). Otherwise, I am at a loss as to what would cause it to suddenly spawn. Keep in mind that it is only this Acropora, not the other two pieces I have, which also look fine.
, so no pics--I am kicking myself for not taking any (if there is a next time, I definitely will). I've had the Acro placed for just over a month, so it is the most established of all of them. I'd really, really like to think it was because my tank is doing so well, but for some reason, I don't think that's the case, lol. That is one reason why I am skeptical--I haven't heard of too many spawning events in corals in average aquaria that didn't involve some sort of stressor. That is why I am trying to find out what, if any change occured. Also, I am not entirely sure it is the actual moonlight that the corals are able to sense--like some birds, etc., it may be some sort of electromagnetic "sense." Anyway, I'm not complaining by any means--just making sure there isn't going to be an imminent crash or something (if you can't tell, I am now paranoid about these sorts of things).
