After Nemo finished his rolling, another 'interesting' thing happened....
Nemo swam back towards the far left corner of the tank, and hung motionless in the water (disclaimed: I'm not 100% this is indeed Nemo, however, the other whale exposes his underside, and there are no ridges, so I'm fairly confident this is the whale I've been describing as Nemo).
You can already start to see in this image, how the water surrounding Nemo starts to get murky (PS: both of these whales are female- I'm told by a visitor to the Vancouver Aquarium).
This is the snapshot that makes me believe, Nemo is at the far end (notice the lack of ridges on the underside of this whale- i.e. probably Wake).
The water around Nemo, continues to look murkier, whilst Wake ignores whatever is happening.
Next couple of images are meant to show how the water continues to get murkier. Nemo also seems to curl up: kind of like the fetal position.
With this sreenshot you can really start to see how the water around Nemo is clearly getting whiter i.e. murkier- as if something is being added to the water.
Throughout, whatever Nemo is doing, Wake seems to be quite content to repeatedly swim past the exact same position (nonetheless, I don't believe this to be a repeat of Nemo's circuit swimming).
Murkier and murkier.
Nemo is still in an un-extended position.
Really murky...
Wake's changing up the swimming pattern- I've never actually seen either of the whales swim down towards the left front corner- interesting.
Nemo's changed position slightly.
You can really start to see the murkiness spread out in wisps from Nemo (who seems to be the point of origin...)
Continuing to emit murkiness, and Nemo's starting to roll again.
Curving around
And another full roll.
Mission accomplished.
Wake swimming towards the camera.
Nemo has disappeared around the boulder. The murkiness remains.
Nemo finally reappears, and starts to swim away.
I'm not sure what the murkiness is, what I'm thinking is it is probably excretion from Nemo- however, I'm not sure if it would linger as long as it did. I will have to look into it.
However, what it may also be, is a human additive. When I worked at a zoo, every day for the seal tank we added a powder mixture to the water, from above. This mixture was white in color, and would linger for a few minutes, producing a similar murkiness that I've seen here. So I think this may also be a good explanation. However, what would be odd, is Nemo's apparent comfort with staying in line with the powder mixture (which is used to prevent algae from growing in the water). The seals would always stay a good distance away from the powder mixture, however, they are seals (which are known for being timid creatures), thus this is not enough evidence to base it off of.
