[azn4114]

i noticed today my convicts are both swimming right at the top of the tank.my water levels are fine.im new to fish and im wandering if this is normal or not?there not breathing any heavier or anything and my other fish are fine and doing usual behavior.

What other fish do you have with them and what size tank?

[azn4114]

Could you test your water and give us exact readings for Ammonia, Nitrite and Nitrate.

What is your tank maintenance routine?

It is strange for Cons to swim near the top as they are usually bottom swimmers, is your Oscar harassing them.

im new to this and i dont know have my own test kit my friend brings his over and he said its all fine.the oscaris not harrassing them at all

What filtration do you run on the tank? ..and are they staying up the top kind of leaning sideways or do they look fine just hanging around at the top?

[azn4114]

my filter is really good,i thought it might be to powerful but my friend said oscars are messy and its needed.there swimming at the top and they look fine not on there side but its like there facing up so the tip of there heads are touching the top of the water

[fnesr]

Is your filter breaking or disrupting the surface of the water to provide adequate airation? ..and do you know the actual brand/model of your filter?

[azn4114]

its an aquaone and yes its breaking the water.they have just gone back to the bottom of the tank now when i went near them but when i walk away they eventually go back up

[Maddy mad man]

Doesnt sound right at all.  How is the oscar?

My first impression is that you might have an ammonia spike.  How long has the tank been set up for and was it cycled correctly?

[fnesr]

If it's the large aquaone (canister) your filtration should be ok (2200Lph on 200L tank). They are quite a good filter, sort of a copy of an Eheim pro. How long have you had the convict's exactly? Are they at the stage where they are comfortable when your around the tank or still a bit timid? If it's not a water issue it could be that they are trying to stay out of the Oscars way, they may of gone to the bottom when you approach as they'd rather take their chances with him then with you but when your not around it's best to stay out of his/her way. Have you got much decor for cover in the tank (caves etc.)? What's the layout?

[azn4114]

it seems alright now.they havent cone up since my last post and both are now in a cave with the oscar they seem to have a bond with eachother 4 some reason.thanks 4 your help guys,your legends
