That dog sure has them hoomins right where he [?] wants 'em ... I can't imagine what the aquarium inhabitants insist they do =oO

And if you liked that, read about this 4 foot sea worm that digests fish hooks and is covered with nerve-murdering barbs!

Yeah really inaccurate >> ^ponceleon:

Very cool video, but the title is entirely inaccurate. The ray was just climbing up the side because they had food in the little plastic cup and it must have figured out over time to do that to get it...
More obviously, that's the wrong side of the stingray...


Seconded. I know from visiting my local aquarium a lot that they know exactly what's going on and are trying to get the food.

Cool critters. I have a conch in a reef aquarium myself.

These giant African snails have apparently become an invasive species in Florida... probably started by some idiots who decided to 'let their pet go' because they were too cerebrally challenged to comprehend the consequences.

Next thing you know they'll try to teach themselves to say Octopus after seeing one in that aquarium book =o)

I started with an 80 gallon that now has 8 discus, 1 endlicheri and 1 senegal bichir, and a synodontis eupterus "featherfin squeaker" catfish.

Now I've got 2 additional 50 gallons that I set up with a Diana Walstad / NPT configuration with a layer of topsoil for substrate topped with small gravel in one tank and sand in the other. Danois and neons in the gravel and tiger barbs and corydoras in the sand. Those tanks work great for strong, heavy planting, and can go for months without any water changes or other maintenance -- quite the opposite of the picky discus!

Always fun to hear about another aquarium lover.

This one ?

Wow that's a large wall of text, @newtboy.
But yes, it appears that:
"Calleja has developed a lighting system that requires no electricity for power. Instead it draws CO2 from the atmosphere and uses it to produce light as well as oxygen as a byproduct. The key ingredient to this eco-friendly light? Algae."
I guess that's why the video empathized that Calleja has been a biochemist for twenty years. i.e. years of research have helped developed a strain of algae with such properties
Apparently the electricity the algae produces is stored in a battery underneath the unit.

The written description said 'with no electricity for power', but the video clearly shows an electric light in the center of the tank...not bioluminescent, electric. They tell you it only works 'in a lighted aquarium'. You even see the operator plug it in and the light turn on at :32, and again at :40, with the electric cord also clearly visible. The audio never claims the device or the algae MAKES light or electricity, only that it takes in CO2 and releases O2. The video of the garage version also shows this clearly, with the plain fluorescent lights turned on while they add the algae to a fish tank. If the power is supposed to be coming from the algae, not the grid, how is the light supposed to be being powered without any algae in the tank? There is never ANY mention of POWER being produced from the algae in the video itself, and the few ways I've read this could be possible are NO WHERE NEAR being financially viable, just possible. They require specialty genetically altered algae (expensive) and reactors with exotic materials to capture electrons from charged algae (also expensive), and the algae must be exposed to light to become charged. If, as the written description claims, they have solved this problem and ARE generating electricity from nothing more than an anaerobic reaction without external heat/light/energy required, you would think they would have said so in the video itself, and made a HUGE deal about it. They did not.
If this really worked without outside electricity added, they could put panels of the algae and reactors outside and run the white light (now inside the algae tank) indoors as a living solar panel/light setup, I note they did not do or even suggest this.
Without the 'magic', unmentioned light/electricity generating portion, this is NOT a new idea in the least as he claimed, people have advocated using simple algae and micro algae to scrub CO2 for decades, and usually in sun light rather than electric light so it's better than carbon neutral. What this really seems to be is a filter you can put OVER a light to make it produce some O2, but it also gives off far less light. There is no indication whatsoever from the video that this is intended to produce light or electricity itself without external power. I can't see where the poster got that idea. Perhaps they are involved in the project and want 'investors' that can't see the difference and can't do any research?

If you follow the chain of reposting and adding more sensational claims that goes through shashdot and their source geek.com you eventually arrive at this site, which has already redacted it's claims about the algae in the lamp producing any light or power.

Going only from what's said in the video, I think the entire point is carbon sequestration. But keep in mind the algae is also absorbing some of the light from the lamp, requiring the use of more lamps to light the same area.

What's the opposite of aquarium? So the mother whale takes her calf to the aerium to see humans?

I have outdoor koi ponds, and I'm into the fish-keeping hobby with aquariums also. With the right ecological setup and filtration/circulation system, I think this would make a great visual element / water garden area for a home, plus providing a swimming area that is cleaner and clearer than your average pond/lake.

If you're squeamish about swimming in a lake or pond, consider that your average public pool is saturated with chlorine/bromine and kid-piss... Pick your poison.

What the fuck is this? TorutureAnimalSift? Next we'll have a shit-ton of videos with assholes poking lions with sticks through the bars of their cages and tapping the glass at the aquarium.
Bullshit. Video doesn't belong here.

I don't find this video anymore objectionable than this for example.
Sorry if my tags and title sounded like I'd find it amusing how those little ones react when captured. I assumed they were treated well in general.

Fair point, but it's the old "Two tortured animals doesn't make a right" quandary.
Also minor difference- the cat was terrified, which is understandable considering the circumstances and surroundings- it was probably confused, disoriented and scared but nobody was deliberately hurting it. In this video the frog is being goaded by someone poking the container with their finger- you can see this on the left side through the translucent plastic.
I stand by the assertion that this is animal torture and doesn't belong on the sift.
Footnote: I've flagged the video on youtube for animal abuse. Hopefully that will take care of it.

Oh, I missed the finger. This puts it in the torture category for me, too.
I just found it hilarious, how the other frog "complained" about the noise
