peppermint shrimp in the display and sump. No more aptasia.

What are the requirements to keep a Mantis in a tank by itself (maybe with some LPS and softies) ? I know the flow doesn't need to be great, neither does the light, but is there a water volume requirement, sand bed depth?

Amazing photos!

I think it's funny you mentioned Elephants. I was recently reading some articles about how scientist now want to declare that various Elephants are subspecies because they've observed significant differences among them. I should add that evolution isn't always genotypes but can be phenotypes (Pepper Moth anyone?) which is the case with Elephants therefore significantly reducing the "evolutionary time" I'll see if I can find it again. phenotype: The observable traits or characteristics of an organism, for example hair color, weight, or the presence or absence of a disease. Phenotypic traits are not necessarily genetic

Fantastic post! But I don't agree with your definition of evolutionary time being millions of years; bacteria and viruses can evolve rather quickly. Look at MSRA for example, H-E-double hockey sticks the Flu is a decent example. In only a matter of years they have evolved resistances to common medications. As for Darwin's birthday? Keg party!

Cool, I'm not familiar with Roozen's but it might be worth going up there just to have a look around

Wow, this is a lot of good info. I wanted to make a small mantis tank but all the information I ever got from hobbyist or LFS was that they're super dangerous, break fingers, etc etc. Are there places around here to find them?

No, I definitely don't think they'd be called racist, I was referring to our current time with our modern technology and abilities to analyze DNA. One of the greatest researcher of genetics was recently roasted when he suggested that those from the African continent were a subspecies, he came forward with his observations after reviewing the DNA and from simple observation (Compare the modern world to Africa). If I'm not mistaken, during Darwin's time they already thought those from Africa were inferior I believe what I was trying to say can be demonstrated in the Pepper Moth. Anyone who has taken biology has heard about the Pepper Moth. In a relatively short span of time the Pepper Moth went from being light colored to darker to adapt changing conditions due to the rise in pollution from the industrial revolution. It remained the same species only with a morph. The peppered moth is one of the most commonly used examples of evolution but it never involves the evolution into a new species. All of this information is found in my very basic college biology book. To some extent I see what you're saying, but this is survival of the fittest. Regardless of whether the initially adaptation occurred 10 years or 10 million years ago, the species, subspecies, or morph which is better adapted is surviving while the other's numbers are declining. You're talking about geographical isolation which is only one time. "Adaptations are structures or behaviors that enhance a specific function, causing organisms to become better at surviving and reproducing."

We don't consider them a different species because you'd be labeled a racist and killed. Additionally we never do subspecies within the human race, everyone gets labeled a Human. Darker coloring in humans, birds, moths, etc is considered an evolutionary trait. Darwin observed Finches, all the same bird, who had adapted and evolved for their particular situation. But if we went by what you mentioned before, it wasn't evolution because they were still Birds.

Well that's basically cheating. I'd definitely want one of these, but I don't want little shrimp corpses hanging from trees in there. I wonder how these things are made, they need to cover them on How It's Made...

I've always been interested in these, on their website under the order section it lists the replacement period. Is this the suggested replacement time frame, the "warranty" period, or what?

I have to agree with MOT, adaption is a factor in evolution. Darwin's original observations were on the adaptations of the finches for the particular location on the islands and the food sources available. "In biology, evolution is the changes seen in the inherited traits of a population from one generation to the next. These changes are relatively minor from one generation to the next, but accumulate with each subsequent generation and can eventually cause substantial changes in the organisms." These changes are brought on the by the need to adapt to a changing environment. That's the basic survival of the fittest. You adapt or you die.

Last longer by days, weeks, months?

What's the consensus around these parts? I'm purchasing a AC III and I want to pick up a pH and Temp probe but I'm not sure whether to get standard or lab grade.

That's what the son of a gun was doing? SOB. I had a tang who used to swim in my hand when I had it in the tank, I thought he was just being friendly. Thankfully he never did any harm.

Definitely a nice piece. When I have my tank up and running I want to try and get my hand on maybe 2 small brown out colonies, sure it's a gamble but isn't everything in this hobby?

I forget which user it is on these forums whos doing the CADlight 39g but I've been following their RC thread and I was curious how the 150 HQI lights hold up? I vaguely remember someone telling me to stay away from 175s but would a 150 be enough for a 30-40 gallon tank or is that trying to cut too many corners?

I don't have a tank yet, I'm in the planning stages. I'm trying to spend more time planning (and plotting) than I do in the actually execution. This way I can eliminate a number of unnecessary surprises and know that the end product will be exactly what I want. Right now I'm looking into 24x24x? cubes and wanted to ensure that the pendant would provide the necessary light for SPS at all places in the tank.

As I'm planning my new tank I've decided to minimize the number of lamps I need to keep around and hopefully be a little friendly on the power bill. I love the look of pendants, so for the time being I think I've decided to go with a reef optix 3 250w 14K. (I'm open to suggestions, this will be my first MH tank, I've traditionally relied on VHO setups or CF) What tank sizes would this setup suit? For an SPS open tank, what is the deepest and widest you could get while still ensuring that coral at those ends of the spectrum are still receiving adequate lighting? It's an ugly question I apologizes I'm not sure how to phrase it more better.

I agree. I found if my zoas weren't directly exposed to the lights and slightly higher in the tank that they would "stretch" to get as much light as possible.

Well now that you told him I'm going to kill him for telling him, he'll know I'm going to do it and will be prepared. I thought we agreed to keep it on the down low and you get half of the loot..thanks

I did, but the checks are so secret only I know about them.

Just curious, how long does it usually take for your paid membership to register? I went ahead and took care of it yesterday afternoon but I still haven't heard anything. Any idea? Thanks!
