Today's New Year's Eve..


As we bid farewell to 2009 and welcome 2010...

my new year resolution for my aquatic hobby would be to be more disciplined and maintain stringent water quality in my tanks!

SYDNEY – Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal.

The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot.

Julian Finn and Mark Norman of Museum Victoria in Melbourne observed the odd activity in four of the creatures during a series of dive trips to North Sulawesi and Bali in Indonesia between 1998 and 2008. Their findings were published Tuesday in the journal Current Biology.

"I was gobsmacked," said Finn, a research biologist at the museum who specializes in cephalopods. "I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh."

Octopuses often use foreign objects as shelter. But the scientists found the veined octopus going a step further by preparing the shells, carrying them long distances and reassembling them as shelter elsewhere.

That's an example of tool use, which has never been recorded in invertebrates before, Finn said.

"What makes it different from a hermit crab is this octopus collects shells for later use, so when it's transporting it, it's not getting any protection from it," Finn said. "It's that collecting it to use it later that is unusual."

The researchers think the creatures probably once used shells in the same way. But once humans began cutting coconuts in half and discarding the shells into the ocean, the octopuses discovered an even better kind of shelter, Finn said.

The findings are significant, in that they reveal just how capable the creatures are of complex behavior, said Simon Robson, associate professor of tropical biology at James Cook University in Townsville.

"Octopuses have always stood out as appearing to be particularly intelligent invertebrates," Robson said. "They have a fairly well-developed sense of vision and they have a fairly intelligent brain. So I think it shows the behavioral capabilities that these organisms have."

There is always debate in the scientific community about how to define tool use in the animal kingdom, Robson said. The Australian researchers defined a tool as an object carried or maintained for future use. But other scientists could define it differently, which means it's difficult to say for certain whether this is the first evidence of such behavior in invertebrates, Robson said.

Still, the findings are interesting, he said.

"It's another example where we can think about how similar humans are to the rest of the world," Robson said. "We are just a continuum of the entire planet."

Neglect

My fish tank has been in a state of neglect of the past week...

Will have to do major water changes tomorrow!

Oyster shells...

While I enjoy eating live oysters....




My fishes do get some indulgence too!

In the form of the oyster shells used for buffering the tank water!

Missing Pictures

So sorry...

If you have noticed, there are some missing pictures in my previous pictures..

Apparently, some server at Shareapic (where my pictures are hosted) has crashed, which explains the missing pictures..

Hope they solve the problem soon!

Nothing feels as good as being home!


My injured betta back at home at last!

Apologies

Wow...

It's really been some time since I updated this blog.... been quite busy recently... but that doesnt mean that I have neglected my fishes!

They are still doing well..

Will grab some pictures and do some updates soon!

It's amazing to see how much new leaves and shoots there are!



And the best thing is that they are growing in indirect light.. with a cling film on the pot!

Wednesday, August 19, 2009

I am quite pleased..


My injured betta is recovering...

No more open wounds!

I thought anubias species were supposed to be hardy...


Apparently not so...

Not sure why my anubias have been turning brown recently...
Anyone knows?

Just some update on the injured fish...


The infected part now has no more white cotton wool growth, seems to be some healing taking place, there is a sudden recess in the body where he got injured..





It pains me to see a fish that I rescued from ending up as feeder fish, turning into a beauty and getting injured..

Get well soon.. little one!

Betta Updates...

My injured betta seems to be doing better then yesterday...


His colour has came back, and the open wound on the fish does not seem to be 'bleeding' anymore... hopes he recovers..

Trying to keep my water very clean to prevent any secondary infections!

Freak accident!

Discovered a freak accident just in time...

My betta that I rescued from a bag of feeders was stuck in an ornament...

Managed to help it dislodge from the ornament.

However, part of its body has been torn.. god knows how long it had been submerged without coming to the surface for water...




Thank god it is alive..

Isolating this little guy, hope it gets well.. before I can reintroduce him back to his tank!

My Cryptocoryne longicauda is having lots of plantlets shoots coming out....

Signs of good environment?

It seems to be doing well in the bottled container..

Let's hope I can get the plantlets into another container at a slightly bigger stage!

New Growth

Amazing new growth from my Crypto Wendtii...




It has sprouted numerous new leaves, which are slightly different in shape from when they are grown submerged.

Hope to see it flower soon...

Crypto updates

An update on my cryptos that I have planted emmersed in the pot:

More new leaves... more foliage.. new shoots too.. the plants have seemed to have anchored themselves into the gravel firmly.

Saturday, July 18, 2009

Wow...

Wonder if this is due to the Great Singapore Sale!



Got this Oto fish food at just a dollar! Think will be great for the fishes in my planted tank!

Red Dye Leaching?

Noticed that my parrot fish tank seems to be a tinge of red in colour!

Which is weird....

Not sure if its due to the colour coming out from the feed!

Not exactly....



More like oyster shells for the filtration system in my parrot tank..

Added these to buffer the water to maintain the pH of the tank!

Sunday, July 12, 2009

I checked on the status of my newly potted cryptos earlier in the evening...
and noticed that they were indeed starting to dry up.

I guess.. living on a high rise HDB flat, winds are definitely inevitable.

As such, decided to use microwave cling film to spread over the whole pot, hopefully, this will aid in maintaining the humidity levels within the pot, while still allowing light in!

Planting Sunday

Wow...

I spent nearly the whole Sunday preparing the planting of my wild cryptos in a pot today...

This post will therefore be a little more picture intensive..

Here are some of the items you will need:

A pot, of course, get one without holes, since crypto will prefer a little water logged environment.

Next, I used some dried sphagnum moss, since these are pretty good at holding water:

How the moss looks like when dry, and after hydration:

Next added some peat moss to the hydrated sphagnum moss, as it supposedly aids in lowering the pH:

After which, I added a thin layer of activated carbon and charcoal, which supposedly aids adsorption of any toxic stuff:

Next, a layer of lightweight expanded clay aggregate was added, this helps to provide some aeration to the roots area, and also aids in the transport of water from the sphagnum moss area to the soil level at the top:


Final layer, I used a different brand of planting soil mix today, as the usual aquarium shop that I frequent is closed on Sundays, and the neighbouring shop does not stock that brand:

Upon completion, its time to take out the cryptos from their packaging, noticed that some of them have broken leaves, bitten worm hole leaves... signs of really wild cryptos?


The completed pot of wild cryptos... note that there is water filled in the pot.. that the top soil still feels wet, but no dead spots of water, as I do not want to encourage the breeding of mosquitoes!

Hope they will flourish well.. placing them in area with lesser winds and indirect sunlight!
