Err strictly speaking, E3 is the one who started it first when she promoted Happy Mama to Ermei Zhan Men Ren.

Excuse me, sir, I address Happy Mama as 师太 out of respect cos of her seniority in rank. Then dunno who hor, prefixed it with 灭绝, then after than dunno who...like nick starting with Capital F promoted her to 峨嵋派掌门人... 小女子 here is innocently filled with awe at her super speed promotions to grand grand grand master. :udawoman:

Err strictly speaking, E3 is the one who started it first when she promoted Happy Mama to Ermei Zhan Men Ren. I only ask whether she looks like 周芷若 but then you have to suggest Botox for the older nun (which we all agree no way is Happy Mama going to be look like her, kekeke). Nevertheless, I have to be honest and admit that *ahem* I'm too young to have the opportunity to watch shows of that era.

Huh Try to Bluff Your way thru? Even I Can't Remember Exact Names like 周芷若 .... Either U Lifted the Name Error-Free from Your Super-Search Machine Or .... U R Smitten with Her? :laugh: :laugh:[/quote]Hmmm now, all of you are trying to confuse me. :? :? :?

Wld someone pls enlighten me how can air enters into the stagnant water in setup A?

Hmmm....I cannot answer you on the fish breathing on the surface stuff because I have absolutely no idea. On the O2/air into water, I rem, long long time ago, I ever read from a text before that air does enter into water w/o pump. But, the solubility of O2 is low in water. For an aquarium, I think pump is used to filter, and pump in more oxygen to supply the fishes. :lol:

How oxygen is dissolved requires in-depth scientific explanation which might need the expertise of a Scientist. However, oxygen in the water comes largely from the atmosphere. Faster moving water absorbed more oxygen compared to still water.
[quote]I was told I needed an air pump for our fish tank, else the oxygen in the water is not replenish and the fishes will die. Was I tricked by the shopowner?[/quote]The fish that my dds brought home from the Pasir Ris Farm can survive without an airpump for weeks. I think they died one by one due to neglect.
[quote]I am always under the impression that fish will swim near the water surface to gasp for air when there is insufficient oxygen in the water (again told by someone).[/quote]Fish do not \"gasp\" for air unless their gills are damaged. They only take in dissolved oxygen in the water.
[quote]but knowing how fishes in water take in oxygen via their mouth n passing the water through their gills, how do the fishes then breathe near water surface?[/quote]My assumption, they swam near the water surface because the movement they created at the surface will cause more oxygen to be dissolved into the water so they can take in the dissolved oxygen near the surface.

Yes, the concentration of dissolved oxygen in the water will vary so there is a need of an air pump or an aerator to maintain the oxygen level in the water. I am no fish rearing expert though. This is what I read and understood.
