cause the small air bubble hose came out..

Bro, what do you mean by " small air bubble hose came out " ? Pls advice.

aiya.. the hose for the bubbles(air pump) got loose la.. Then no oxygen in the tank.. it died due to suffocation.

Usually this fishes need super duper clean water in order to survive.

Possible Causes: Pseudomonas Fluorescens, Aeromonas hydrophila

Infectious: Yes
Reoccurrence: Yes

Symptoms: Fish floats to the surface, often upside down, and is unable to swim down. Alternatively the fish may be unable to swim off the bottom of the tank or fails to swim upright instead it rolls from side to side.

Other characteristics: Poor nutrition [may subjected to appear thin even though is eating well], body near the swim bladder organ may appear swollen, disintegrating of colour [may appear blackish]

Introduction Aeromonas Hydrophila

- Is a pathogenic bacterium
- Bacterium can be found in marine, brackish, fresh, chlorinated and unchlorinated water supplies worldwide
- Resistance to chlorine, cold temperatures
- Able to survive in polluted or poor oxygen environments
- Travels via bloodstream to the first available organ (my guess would be the swim bladder organ)
- produces Aerolysin Cytotoxic Enterotoxin [ACT]

Introduction Aerolysin Cytotoxic Enterotoxin [ACT]

The toxin binds to high- affinity receptors and undergoes oligomerization to form a heptameric pore- forming complex which allows passage of small molecules in the plasma membrane, resulting in permeabilization of the cell, cell death, and eventually tissue destruction [taken from

In English, basically the bacterium produces ACT toxin which forms polymers aka oligomerization (consists of two, three or more monomers). It means that the lining of the swim bladder organ thickened, thus interfering with the exchange of gas into the sac or reduced sac elasticity.

NOTE: A fish may use its swim bladder to move up and down in the water by taking in and release air through its sphincter (I think found the anus maybe?). That’s why swim bladder problems have three types of problems. There are Headstanders, Tailstanders, sitters and Sleepers problems.

Headstanders type are fish which ‘stand on his head’, Tailstanders type means refers to fish which are ‘sitting on his bottom or anal fins’ and lastly sleepers are to those fishes is ‘sleeping’. [Taken from http://article.discusnews.com/cat-02/swimblader.shtml ]

Bro Rocfreaks explanation is very detailed and well researched. Good to understand and to adjust our feeding regimens for goldfishes.

For arowanas, i use injection method by releasing the gas from stomach. this is done by many aro farm and needs experience fellow to do it.
