|
I am asking this question because I am really not certain what caused my oscar (7-8") to bang itself to the walls of the tank and try to jump out until I switched off its power unit for filter and heater.
I have got the absolute cheap class chinese filter we easily get all LFS. and a Sobo heater 300 watts.
Not sure if this equipment is leaking some current or if there is something I need to know about the fish's behavior.
Please share your experiences and solutions.
Thanks! |

| Glass does not conduct electricity. Given this, a fish in an aquarium with a live wire dipped into it will not feel an electric shock (because there's no earthing to close the circuit). In the past, I have used broken heaters in the tank with no adverse effect (of course, the broken heaters were used for a very short time till I got a new one). |

+1 on Shankar's reply.....spot on.
How often have you seen your Oscar banging itself , How big is your tank.
Are they getting spooked for some specific reasons like...
When somebody walks into the room
When a light is swithched on
When someone accidentally touches the table a little hard on which your aquarium rests
How often do you clean your aquarium...reason I ask is...more frquent cleaning never allows your fishes to settle down |

Frequent cleaning of the tank does not allow the fish to settle down.
Just a consideration: Why don't you provide the oscars with some natural places to hide or just make the tank a little more natural than a bare bottomed tank? Some driftwood, smooth surfaced rocks etc.? |

Glass does not... but faulty electric connection can? I am suspecting that there is a water leakage on the cieling, causing the wires to go faulty. Do you think this might be the cause?

My tank is 3' x 1.25' x 1.25', fish is 7-8 inches in size. I am not sure what causes this behavior, as I have seen times, when even the room lights are off and he starts going crazy! Its on the floor, so 1 possible reason could be continuos distrubance... or may be not... I am not too sure abt it
I used to clean the tank 1 every 2 months, and weekly 50% water change. In the past nearly 2 months, he was ignored badly on this front.

As just highlighted, frequent cleaning is not done at all... infact its now a days being done least! |

OK. One thing that caught my attention from what you said is this: the tank is on the floor. That def can be the source of your fish's discomfort.
A) constant walking, thumping of foot can be def felt by the fish.
B) the fish always sees an 'animal' peeping from the top, which IMO is not liked by many fishes. I have seen in other websites that sudden shift in shadows too can scare fishes.
Given this, the most inexpensive option for you to try could be to put the tank up on a pedestal. You can also try placing some potted plants around the tank to give more cover and shade to the fish. |

| Fish will not feel shock as already said unless the earthing circuit is complete. |

Actually fish will not feel the shock even if ciruit is complete  because water stays at same potential uniformly around fish's body.
Its we who get hurt because our hands will be in some voltage and foot zero, so pHaAtT!! As current pass through us.
But if U ask how electric eel jolts you down, that's something more interesting to discuss. Also electric rod fishing.
Anyway even I don't attribute it to current leak, but either due to ammonia spike or aggressive fish or foot steps as our members have said. |
