for the last three to four days my oscar has been sitting in the corner of my tank on the bottom he comes up for food but imediately heads straight bak to where he was. i also have a green texas in with him. they have lived toghether for at least three months and there has been no aggression till now. is this the problem or something else. i have a short video attatch any help would be greatly appreciated. im really worried he might be sick..

No video Hun!

And I would separate the two as the Texas IS NASTY!!!! Not a good pair!

sorry should be vid now guys thankyou

still no vid.... Where are you putting it? Or how are you uploading?

no video yet. the vid would help us understand what was going on.

The easiest way to post a vid is to post on youtube, then just copy the link directly in the subject.

while waiting for the video to work... any info about your water?
ammonia level?
Nitrite level?
nitrate level?
pH?
tank size?
filter capacity?
water maintenance?

having fish for three months and sudden change in attitude requires
knowing your water parameters...

there is 2 possible reasons

The most likely is that the texas is bullying your oscar, any marks on the oscar and have you seen the texas chase and hassling the oscar

The least likely reason is poor water quality

So we need water tests for ammonia, nitrite and nitrate, and also that vid
