I sent him the image.<br />He recognized it but didn't know what it was. He was going to contact<br />friend he sees as an expert. <br><br /><br><br />And that was the end of that search trail. I never heard back. <br><br /><br><br />Beginning again I searched [ saltwater aquarium problem pearl-like ] to<br />go to <a href="http://www.advancedaquarist.com/2010/4/corals" rel="nofollow">Aquarium<br />Corals: The Bubble Corals: Species of the Genera Plerogyra and Physogyra</a>.<br />In the article they mention "pearl bubble" coral so I search for [<br />"pearl bubble" coral ] and then [ pearl bubble coral ] and don't really<br />find anything useful. I take a gamble at looking at the images. Way<br />down on the page I found 1 picture that looked slightly similar to pics<br />in the post. On a page of pics called <a href="http://delargy.com/2009_04_Cozumel/Coz_Shore.htm" rel="nofollow">Cozumel Shore<br />Dive</a> and half way down the page I see a picture that is labeled<br />"sea pearl" aka "sailor's eyeball" - a one-celled algae.<br><br /><br><br />Search [ "sailor's eyeball" ] and the knowledge graph shows it as<br />Valonia ventricosa and the picture looks familiar. Search [ Valonia<br />ventricosa ] going on to the Wikipedia page <a href="http://en.wikipedia.org/wiki/Valonia_ventricosa" rel="nofollow">http://en.wikipedia.org/wiki/Valonia_ventricosa</a><br />So I think I have the name. <br><br /><br><br />Search [ saltwater aquarium bubble algae treatment ] and find post on <a href="http://www.reefkeeping.com/issues/2002-02/hcj/feature/" rel="nofollow">Bubble<br />Algae</a> in Reefkeeping magazine. The article lists 3 controls. Only<br />one of them fits biological agent 2. Suppression via appropriate<br />herbivores. I went back to beginning of the article and something<br />caught my eye "there is this added twist: the much-cited 'Valonia' of<br />our nightmares is no longer Valonia, but, thanks to Olsen & West<br />(1988) now has its own Genus, Ventricaria." Interesting! <br><br /><br><br />Search [ Ventricaria ] followed a few links but not much info gained. <br><br /><br><br />Back to finding a biological agent for controlling this aquarium<br />problem. Back to Bubble Algae article and it lists certain types<br />of snails, crabs, fish and urchins. I went back to the SERP for [<br />saltwater aquarium bubble algae treatment ] and take a look at the<br />video where there is a lot with suction tubes and finally gets to a<br />biological agent 8:19 mark <a href="http://youtu.be/MeqtPe3XukM?t=8m19s" rel="nofollow">4 Ways to Remove Bubble<br />Algae From Your Reef Tank - YouTube</a> An Emerald Crab! <br><br /><br><br />Searched [ emerald crab ] and the scientific name matches the crab in<br />the Reefkeeping Magazine. The article mentions that the crabs may eat<br />other things in the tank and the video said that the pincers of the<br />crab could pop or pierce the algae causing it to spread. <br><br /><br><br />1. Either Valonia ventricosa or Ventricaria aka sea pearl or sailor's<br />eyeball<br><br />2. Mithrax sculptus aka emerald crab<br><br />3. Two possible problems - The crab eats other things in the aquarium<br />you don't want them to eat or they can pop the bubble and spread the<br />algae. <br>krossbowhttps://www.blogger.com/profile/07877826327758153784noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-10880441742116406942013-09-25T14:27:46.672-07:002013-09-25T14:27:46.672-07:00I think there is something about my answer that th...I think there is something about my answer that this comment system does not like.

I figured that other people diving in Bonaire probably took pictures of similar creatures, so I threw a bunch of terms at a Google image search: Bonaire diving coral reef pearl pest. That didn't turn up anything useful, so I added the word "algae," since the big bubble thing in your picture looks like it has something algae-ish on it. Not much there. I removed "pest" and tried again, and got a bunch of image results that looked like a match. ATJ's Marine Aquarium Site (http://atj.net.au/marineaquaria/default.html) confirmed the scientific name. A quick Google search of the scientific name provided more common names.<br /><br />2. A Google text search for "valonia ventricosa control aquariums" (no quotes) turned up a common biological control agent: the emerald crab. One of the earliest hits was a 2008 article in the Journal of the Marine Biological Association of the UK entitled "Efficiency of using emerald crabs<br />Mithraculus sculptus to control bubble alga Ventricaria ventricosa (syn. Valoniaventricosa) in aquaria habitats." Subsequent searches of "emerald crab bubble algae control" (no quotes) confirmed it.<br /><br />3. It seems like introducing emerald crabs to your tank is a trusted way to get rid of the bubble algae, but searching "emerald crab problems" (again, no quotes) turned up a couple of accounts of emerald crabs being so good at eating all of the algae that they ran out, got hungry, and started munching on the coral in the aquarium.RI Curmudgeonhttps://www.blogger.com/profile/05733812059947019261noreply@blogger.com
