Corailline's JBJ 28 gal. Acropora polyps.

Thanks m2434,

It may very well have nothing to do with the GSP. I agree with trying to keep sps or any corals for that matter from different geographically locations does have it's challenges.

 

I'm so sorry to hear about your clown and tank in general. I hope things get better! You have such a beautiful tank!

 

yeah collection location is really important, but we hardly think about it. Really to keep corals happy, we need to know what their natural environment was, but usually this is a guess. LPS will tell you when they are happy with the environment, but with SPS the only indicator we have is PE, but that isn't actually a great one as really all it means is that the coral feels safe enough to feed.

Also BTW I didn't say GSP doesn't have anything to do with it.... May or may not, idk. By itself It would appear it isn't enough to do damage as other corals aren't effected. However combined with other factors such as stress from an incompatible environment or pathogens it's lineage was never exposed to, may just be too much for it.

Thank you.

Well I will just consider removing the GSP as a little experiment. Although it will not prove conclusively it should be a good indicator as to whether the it does have a negative effect on sps.

Having a nice clean black back wall again will be worth it in it's self.


;D

 

Certainly will help with the minimalist thing ;D

Polyp extension doesn't even mean the coral "feels" safe enough to feed. PE is used by hobbyists as an indicator of the supposed quality of a specific coral food. Unfortunately, this belief is not accurate. Chemoreception is NOT an indicator that a particular food is good. If you don't believe me, empty a packet of sugar into your tank and see what happens. The C (Carbon) in that sugar is not in a useable form yet. It might be ingested, but it won't be digested. Chemoreception will often cause them to react. This is why Marine Biologists don't examine polyp extension. They take representative samples and examine their guts. That's how I know that phytoplankton feeds VERY FEW corals but it will feed them indirectly.....based on the work of Marine Biologists and their "coral gut" studies.

 

When you use the term Chemoreception, I would have to think not only chemoreception, by the coral to said additive but also, chemoreception, between corals, a cascade effect so to speak


LOL Curt way to muck up a currently depressing thread with scientific gobbly gook. This is why I like you. :

 

by "feels" I am referring to "feeliance" this occurs when there is an availability of food and conditions which correlate with a lack of predation. This is a technical term though, so I used the less scientific root of the word






J/k.

I completely agree with you. I'm sad about your clown. I'm concerned about your two corals at issue but I believe Dingo addressed that well. We (reefkeepers) are the biggest scientific studies there are. Why do you think Marine Biologists pay attention to us? There is soooooo much that Marine Bioligists don't understand and only a very small percentage of this info filters it's way all the way down to the hobby. They pay more attention to us (SADLY) more than hobbyists pay attention to them. I think it would be better if there was a SHARING of info. Unfortunately, reefkeepers have driven so many amazing scientists away. They don't leave the hobby. They just leave talking with the hobbyists.

 

The problem with sharing data is while we have a lot of data, we do not have good data. One of the worlds leading biostatisticians once told me, "we can do a lot with data, but we can't make it better". Marine biologists have much better data, they just don't have enough of it. This is because marine biology is a very low funding priority. We have a lot of collective observations, and experience, i.e. anecdotal data, however, it does not come close to being useful data from a scientific perspective. Perhapse if we understood the existing scientific research better we could help formulate testable hypotheses based on our experiences. However, no researcher gets funded without a good prior and no good prior is based on anecdotal evidence. Not many hobbyists have the know how to produce valid empirical data...


Sorry Cheryl, mucking up your thread again I do agree that corals can sense each other through chemoreception. There is scientific evidence for this. Also, though, I think some corals are like vacuum cleaners filtering out everything in the water column.
