I got a 8month old Oscar, but during the past few weeks now he has been busy carrying stones from one end to another , does anyone know why is that?, also just got another osgar today and i split the fish tank or awhile so the other one doesn't pick on him

This is very common O's love to move there tank around. You should remove the divider and see what happens just keep an eye on them for a couple hours. How large is your tank?

O BTW welcome to OFL!

hi , tank is 4foot and 2 foot high, I got rid of the old 5ft tank moved house.by the way thank you,

how big is your tank, and filters? This is common behaviour for Oscars. They will decorate the way they see fit. lol

And Welcome to OFL

mine do it all the time dont worry about it, welcome to ofl

thanks for the comments. i got 2 ,2inch osgars and 5-6 inch osgar that why i thought i better put i divider just in case or should i just leasve them and see what happens, they do say 3 osgars are better than 2

That is normal. My O's take all the rocks and pile them up on one side of the tank. I purposey bought real heavy decor for my tank so they would not push and bust glass. Enjoy your O's and your tank. Have a great day!

im not sure who they are but 3 is not a good number for oscars. if by chance you happen to get a pair then they will make life very difficult for the third one.

also for a tank that is 4x2 anything more than 2 oscars will be overcrowding and make keeping your water in good condition very difficult when they reach full size.


and also welcome to the site

Oscars will rearrange the tank how they want it. This moving of gravel is why you should push any rocks deep into the gravel.

3 oscars can lead to trouble, if you get a breeding pair the third will get battered, if you get 2 males leads to fighting

normal thing for oscars to move substrate... and when you do have
a decent size rocks, lifted by the fish, and drop it...can break the
bottom plate of your tank...it happened to me twice....
