  1. look like hydroid medusae, or maybe small sea spiders (pycnogonida) .
  2. If you want to make your pot plants produce buds, then use the red "bloom" light. Apologies if this violates forum policy, but that is truly what the bloom setting is for. Macroalgae do not produce flowers, and will want a balance of red and blue, and it does not hurt to have some of the middle of the spectrum as well. I do not expect that the red is hurting your algae, but it is not likely to be helping. I have had Chaetomorpha growing well in near-zero phosphate, and have more trouble with it if the PO4 gets too high. Mine waxes and wanes for unknown reasons, so it may be something like that, or it could have become too dense and had poor circulation on the interior of the clump.
  3. I first thought the title was "Dead Fish Care." I figured you could either cook or toss it, depending on freshness. I have this problem all the time with the FW loaches. They lie in the most unlikely positions in the middle of the day.
  4. I am in a biology department, and have access to RO water and an IT department willing to let me hook up an Apex controller to the LAN, so have it a lot easier than most. Before you set it up, make sure they don't shut off environmental controls on weekends or holidays, and that they do not spray insecticides. My office got to 99 degrees on July 4 this year (saved by the chiller), but in previous years, I learned which animals can take the heat (sea slugs) and which can't (amphipods) before I understood that facilities shut everything off during holidays.
  5. My tanks always sit high, so I miss out on the top view. Good point.
  6. This is why I hesitated to post anything. No matter how bad a businessman is, someone will defend them. I stand by every detail of my story, and have the emails to prove it. I eagerly await additional details. If he has been thrown under the bus, he earned it.
  7. This may sound heretical, but has anyone but me gone back to glass lids on their tanks? I haven't used glass tops on my coral tanks for about 18 years, but have recently gone back. It started in my algae culture tanks, when I realized that growth was not limited by light intensity, and I put the lids back on my 90 reef while I was away this winter. Even with some splash and salt deposits, I only lose about 20% of my PAR, but I'm only using the LEDs at 60% anyway. Cuts the evaporation rate by about 80%, so I don't have to think about the ATO as often. Corals have as much color and growth as ever so far. Anyway, is it time to rethink the topless thing? Now that most people have shifted to LED fixtures, which put out more than enough PAR, and don't have the heat issues of halides, is there a benefit to being lidless? I guess is looks cleaner, especially for a rimless tank, but otherwise it just means you have to top off more and use some form of screen to prevent the occasional fish jump.
  8. You saying I post too often? The anemone never splits unless it's really stressed, so I am hoping not to see a split for a while. You're first on the list, though.
  9. I just installed a Reef Breeders 48" V2 LED light, replacing the old IT2080. Love the low profile and the excellent colors. Thought it was a good time for a long-overdue update. Full tank shot. The anemone now owns about half the tank, with an island of mixed corals on the other half. The clowns love their mcmansion. They were posing, so I played with the macro function. The angels and engineers are being shy, so no photos of the rest of the fish today. Softies and hammer. The 27 cube with turtle grass and Bryopsis (for the slugs) has been enjoying the nutrients from the 90, and is getting overgrown. Time to thin the grass. The slugs are happy, though. This photo actually shows two, but they are squished together while mating. Some eggs from a recent brood. The group is producing about an egg mass per week, on average. Out for a morning crawl. More soon.
  10. Agreed. Also, do you have tridachnid clams or something else that the pyramidellids will parasitize? Otherwise, you may as well ignore them.
  11. I would be comfortable with a lot more fish being "beginner unfriendly." As pointed out in various posts above, it would have two positive effects. First, fewer beginning aquarists would buy fish they are not yet able to care for. We have all made those kinds of mistakes, and they will continue to happen no matter what, but higher price tags will discourage at least some bad choices. On the other hand, this is where a lot of the money is for the retailers, because an experienced aquarist can keep a fish for years, and therefore not buy much of anything once the tank is stocked. I haven't bought a fish for at least 4 years, so am not contributing much to the industry. Second, it will encourage captive breeding. One of the problems breeders like ORA face is that it's cheaper to buy many wild caught fish. They had to stop breeding mandarins because they couldn't sell them, for example. I expect that the number of species available will go up, and the prices will go down, when fish can be raised on a much larger scale. In my fantasy world, rare fish like carmabi basslets, which are very difficult to collect, will be more widely available once they are bred in captivity. I still think there is a big place for sustainable collection, which benefits local communities. The problem is that the industry has never come up with a credible way that we aquarists can be sure of the origins of our fishes. None of us want to contribute to the destruction of reefs for the sake of our hobby, but we have to trust an industry that, by necessity, wants to keep costs down. It's ironic that Hawaii, with some of the best practices, cut off collection. And Happy New Year to all.
  12. Nonsense. They can simply not sell them. By my count, Arking Mark has killed 5 so far in his "studies," with only one survivor so far, and he is more conscientious and experienced than most. I expect the pair will end up dying in the hands of another "expert" who doesn't understand his or her own limitations. Given the hundreds of species of all shapes, sizes and colors, I am at a loss as to why a retailer can, in good conscience, sell fish that are almost certainly going to die. The reefs face huge challenges, and I honestly don't know how big an impact this kind of activity has, but I do know that it makes the hobby look bad.
  13. Has it really been two years since I last updated this thread? Lots and lots and lots has happened in the meantime. The colony is increasingly successful, and we are gearing up for another semester of experiments in the spring. One of the biggest changes in the replacement of the old, narrow slug system, with one that provides better access to everything. The top two tanks are a 20L for Bryopsis pennata, and a 15 regular for sea slug stock; the middle row has half-height 5's and 10's for Bryopsis plumosa, and the bottom has the sump, Apex controller, and a doser for NO3, PO4, HCO3, Ca, vinegar, and micronutrients. The biggest breakthroughs have been: 1) figuring out the conditions for sustainably rearing enough Bryopsis to keep the slugs fed. 2) finding out that the babies will only eat B. plumosa, and not B. pennata. They look very similar, but plumosa is finer. They start out very cute... Soon they have rhinophores and parapodia... and before you know it, they are all grown up (the girl below is about 2 months old). I am still fine-tuning the rearing procedures to be a little more predictable, but I am on the third generation. I just collected an egg mass from which I hope to rear the exact right number of little slugs for the students' experiments. They are susceptible to starvation and attack by protists during their first weeks of life, but at any other stage the eggs and baby slugs are essentially bulletproof. It will be exciting to do some neuroanatomy. Big thanks to WAMAS, by the way, for providing funds for some of the reagents we have been using. I hope to be able to show off some of the results before summer.
