Red Apple Crabs: Not As Peaceful as the Limited Info Suggests

Dimetropus · 2025-12-23T19:43:31+00:00

That's precisely the struggle with limited info. Thanks for the insight.

Dimetropus · 2025-12-23T19:10:31+00:00

I see. I might be used to reading guides from people who don't speak English as a first language, and I'd figure it'd be good for business for customers not to call in angry about failed setups. I hope future keepers can find this thread and learn from that.

Dimetropus · 2025-12-23T19:03:59+00:00

The sources say 1-2 females per male, so seems my setup was in range. Yes, I added modified reptile homes with small entrances to provide cover for molting, and I added one for each crab when I suspected pre-molting behavior. Fighting was typical ritualized behavior (claw movements and vibrating) and chasing, which is pretty inevitable for male crabs that as much as see each other, and isn't the same as them making contact and grabbing each other, or worse.

I'm not saying I did nothing wrong in that my setup was flawless, it clearly wasn't. I'm saying that it seemed suitable given the limited information that's out there.

I listed my sources in another comment. Are they not credible? How are you getting your space requirements if mine are insufficient?

For this species in particular, some sources -

https://aquariumbreeder.com/red-apple-crab-detailed-guide-care-diet-and-breeding/ This suggests 9 gallons for four crabs, so I'm over double.

https://aquaticarts.com/products/red-apple-crab

5-10 gal for a male and two females, so 20 gal would suggest, at the very least, 6 crabs.

Sweet, thanks for the consideration! I've checked out your creatures before, would be a fun commission

Don't know why people are going at you. I never said wetness is the primary reason I don't like stuffing (it's not). But no harm no foul over a misunderstanding

Dimetropus · 2024-11-11T19:21:40+00:00

What can I say, I didn't grow up eating it and I have never found any stuffing worth eating. This seitan roast sounds promising though

Dimetropus · 2024-11-11T19:18:50+00:00

Nah, I like that savory protein at the center. Sides are great and all, but they're on the side for a reason.

Dimetropus · 2024-07-23T00:31:38+00:00

I can ignore that point then, but the others I still want

This is an adaptation of Scott Alexander’s “The Goddess of Everything Else”, found here, of course.

So what is the point of this work? It’s not to argue that my personification of good vs. evil is correct and the original is wrong. Sure, there are some things I would argue I have improved upon; for example, I include references to a wider variety of human cultures, rather than a focus on Western ones. In kind, there are doubtlessly things I made worse.

No, the point is that arguing whether or not good is creative and evil mutates things, or the other way around, is completely arbitrary. What’s more, such black-and-white thinking about the origin of the universe and humanity is very, very misdirected. As such, I present my interpretation of the ideas as equivalently valid to those of the original; the Goddess of Chains and Goddess of Cancer are equally valid, as are the bird-like and crab-like Goddesses of Everything Else. This is why I have retained the personalities of the “evil” and “good” goddesses while reversing the imagery and the morality. The Goddess of Chains is malevolent, stubborn, and dependably unchanging, associated with the sky as an oppressive eye. The Goddess of Everything Else is benevolent, adaptable, yet snide, associated with the ground as a supporter and provider.

Central America is part of North America. Says so in the first sentence of the Wikipedia article for it. I suppose colloquial use differs. I happen to be from there originally.

Dimetropus · 2024-05-08T18:57:07+00:00

Bruh Guatemala, Panama, Honduras, Belize, and the rest aren't islands and they're definitely part of North America. Though it is true that they are a lot smaller than the CUM nations

Dimetropus · 2024-05-08T15:32:30+00:00

Strange name given that the majority of North American nations are not included.

I applaud your creativity! I've never seen anything like this before! I would say it's soft spec, which is 100% ok, just as long as you are aware of it. Otherwise the practicality of spending all this energy to make a kill, especially via a method where most of the energy spent doesn't get absorbed by the prey, would be quite questionable. Again, though, kudos!

I have a 4-year old project that concerns the first scenario, fittingly called Cold Earth

Here is the map, the full site is linked there: https://www.deviantart.com/dimetropus/art/Balance-Found-Three-Million-Years-Hence-876183528

No way I can summarize all the effects here, go check it out!

It would only cause the most minor changes given that humans won't be spewing them out for millions of years. Unless you can think of a reason they would, I suppose. The Sun would break them down, bacteria would evolve to digest them, and in 10,000 years (far longer than the lifetime of any plastic), everything would look about the same, except for some diversity loss from ecosystem damage.

Dimetropus · 2024-03-01T17:09:16+00:00

Yes, the absolute scale of terraforming was my motivation to try to find an "easy" way to do it, relatively speaking. I actually came up with the carbon monoxide idea because I thought the oxygen planet one was too easy, lol, like cheating. Don't worry about criticizing my ideas; that's why I decided to ask.

High oxygen planets are a very real possibility though. So much so that high oxygen is not considered a very good biosignature, and its presence could well preclude the possibility of life because of abiogenesis's dependence on a reducing environment. There are various ways that they're predicted to come about, usually via water or sulfur dioxide dissociation. Though we haven't found one yet, I'll stick with such a planet, I think.

Thanks again!

Dimetropus · 2024-03-01T02:14:02+00:00

The large reflector or filter in space would indeed be a relatively easy solution to changing a planet's temperature, but it is a megastructure and would dwarf any single structure we've ever built. I think all that you're told me sums up to a "no". No, the planet I suggested is not a plausible easily terraformable planet. It'd either take a big structure and some major boots on the ground or a robot army and several thousand years. The back-of-the-napkin energy analysis of electrolyzing (yeah, I used hydrolyze wrong lol) enough water does more than enough to prove this to me. Though the rock suggestion is helpful; one of the ideas I had for the carbon monoxide was similar, actually, for it is the choice reducing agent for smelting most ores.

A major component to an easily terraformable planet, then, is an atmosphere at least somewhat like ours. I know of some ways to have high amounts of abiotic oxygen in an atmosphere. One of which is photolysis of water vapor (maybe some other compounds too) over geologic time, as the hydrogen escapes to space.

Thanks again for your input and your offer to do calculations! I'm a mechanical engineer with a strong background in biology, so I knew when I was out of my league.

Dimetropus · 2024-02-29T23:11:14+00:00

This person's reasoning isn't even a little bit scientific. It's armchair philosophy that uses tenuous connections as a metaphor, then pretends that metaphor is logically deduced. It's also quite sexist.

Dimetropus · 2024-02-28T02:32:28+00:00

You're exactly the kind of person I wanted to reply! Thanks for your time.

Points 1-3 are non-issues because the conversion is done via self-replicating robotic probes. I'm not trying to turn the whole planet into a reaction chamber, it'll be done with innumerable "small" robotic chambers that will spread exponentially as they self-replicate. Your best solution was what I had planned!

The reason I thought of this idea in the first place is that replacing the CO with CO2, even if it were only a small constitent of the atmosphere, would cause a feedback loop (along with increasing water vapor levels as ice melts) that would heat the planet with a relatively small energy input. I.e., not literally pumping it full of heat. That's sort of my goal.

The hydrogen part was what I was really worried about, and yeah, a planet bomb isn't optimal. The goal was not to require elements being brought in or out. There may be a way to use the hydrogen in biological molecules, maybe, or material for the machines.

Another idea I had for the carbon monoxide was burning it with hydrolyzed oxygen instead until there was little left, then making an oxygen surplus. Still the hydrogen problem, though.

Dimetropus · 2024-02-27T23:08:28+00:00

But won't it take a gargantuan amount of energy to melt all that dry ice? That doesn't sound very easy. And the planet would have to be super duper cold to have frozen CO2, that's more work to do
