    Rimless 180g "2nd child"

    I can certainly appreciate how frustrating it can be not knowing why a coral(s) die. I am glad to see you post your efforts and test results. As Victoly pointed out there are some serious reservations about ICP testing but having test results along with your observations It's still potentially valuable information others can use to help identify issues. ANd having seen corals from hte same clone line respond differently to what appears to be the same conditions the limited testing we have available indicates the more information we have the better we're going to be able to keep these animals for their normal life expectancies. I am curious exactly where the tin is coming from as my tests of tap water here didn't show any tin. While most of our water comes from lake Travis I know there's a lot that comes from wells or private water utilities that may treat thier water differently than City of Austin.
  2. Anybody seen color change in Montana White Ocellaris Clowns as they age? This male was purchased as a juvenile from River City at C4 2016. Over the last couple months the back third of the body has shifted from bright white to grey. It's behavior hasn't changed any and standard colored ocellaris will usually show some shift in color to brown as they age so I'm assuming this is what's happening with this one. Just wondering how common this is with Montana Whites. If it's typical it would certainly be a factor in getting them in the future.
  3. Saw your FB comment on your shark on Jennifer's post but didn't want to hijack her post. Regarding nitrates and your shark; you definitley want to get your nitrates down. I suspect the cloudy eye is bacterial like in fish but high nitrates will cause other health issues long term for your shark. Nitrates are also not good for your corals either, tending to push the mutualistic relationship between corals and zooxanthellae towards a parasitic one in favor of the zooxantheallae.

    Alkatronics or Aoex

    Autofeeders that utilize a rotating hopper can be an inexpensive option option for adding dry supplements also.

    My First Skimmerless System

    Here's a video from a couple weeks ago. https://youtu.be/cWIEKUsjnYU

    New tank cycle

    From your posts it sounds like you added some live rock that had hermits on it. Between adding bacteria and using live rock I wouldn't expect any nitrites to show up for long even if it was ever at detectable levels. For what it's worth I haven't had a nitrite test kit for 15 years or more.

    Aluminum tank stand.

    Looks really nice! Having seen steel stands for tanks 10X the size use only 1" square tubing it looks like you went for some serious overkill there.

    Reef 1992

    I thought I had a thread on thsi system but just hadn't updated it since it was rehomed 5-6 years ago. Even though I have referenced it in posts in the past I apparently haven't actually started a thread on it so here it is. The system was started in 1992 and has brown finger, Palau Green Finger (Sinularia foliata), Discsoma sp. mushrooms, Tricolor Frogspawn all added mid 90's. Purple Tang initially purchased 1994 and rehomed 2007. FIlter is just a cryptic sump (skimmer was removed ~'97-98). Lighting initially was T12s then T5s then LED bars and currently is 3 "PopularGrow" 3' LED bars. (Notebly the mushrooms that thrived under fluoresents for 14-16 years have never done well under LEDs) System still has a couple pieces of the original Florida Worm Rock which a few old timers might remember. Originally set up in a 75 gallon system the tank has been moved and replaced several times and and rehomed once and it is now in a DAS 110. https://youtu.be/Pc1Ahpyaxb8

    Repairing Acrylic Sump

    In addition, you could also reinforce the joints with acrylic rods. Clear swizzle sticks would be a good diameter I think.

    Hair Algae, a second case study

    Here's a time lapse of a spot showing the changes in algae as the herbivores graze. It can be clearly seen there are spots in the nooks and crevices that have algae the herbivores can't get too but there is no hair algae growing. https://youtu.be/vxMn6YBwIDM

    Royal Gramma larva

    I did get rotifers used for clowns but I didn't see any feeding. Size may have been a factor or maybe species. Benroman has raised clowns and is looking into it. Unlike clowns that lay a large batch every few weeks female grammas lay just a few eggs daily and the location of the male's nest is known getting more eggs to work with should be much of a problem.

    Here's pics of the egg mass I forgot to add yesterday. Their roughly a third the size of clownfish eggs

    Royal Gramma larva

    I've been pretty sure for a couple decades grammas in my tanks are breeding but this is the first time I've seen and recovered an egg mass from the male's nest. The video is shows the larva at about 18 hours old, assuming the hatch at sunset (lights off) like clownfish. They are much smaller than clownfish larva, the faint grid on the background is 1/4" graph paper
  14. It is a very complex picture. Many species are tolerant of each other. Many are not. What's missing is long term data, as in decades, of the successes and failures. What is the mix of species being kept? There are different microbial processes at every taxonomic level, Kingdom, Phylum. Class, Order, Family, Genus, SPecise and even Genotype and many of these microbialial processes are antagonistic. What are the long term ramifications of these processes especially in light of aquarists, often questionably, manipulating environmental conditions accentuate colors of corals? Unfortunately what is apparent is a very high failure rate and reports of supposedly healthy systems going down hill, many very suddenly with significant dieoff in a very short time. It's very rare to find an aquarist that's maintained the same system with the same animals for decades.
  15. It really doesn't matter the genus, species or genotype, if there's kill off the animals should be separated. While the risk infection will depend in part on the immune system of the animal involved, which can vary significantly at the genotype level¹˴², there's still going to be an increased risk. Depending on the environmental stressers the animals are also exposed to (increased nitrates or phosphate defiency are two obvious ones) once an infection gets started in a colony it can not only kill off the entire colony quickly it can also spread to apparently healthy animals whose immune systems have also been compromised. It's also a mistake to assume a corals microbiome is comparable to a wild coral's, one of the surprising discoveries is a coral colony's microbiome is significantly altered just by placing it in an aquarium³. 1) https://www.nature.com/articles/s41598-017-02685-1 2) https://nsuworks.nova.edu/occ_stuetd/467/ 3) https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.1462-2920.2009.01935.x
