Heres a couple of pictures of my O's with the new pool table slate I put in.
And my Red O' turned albino now and the darker one turned into a red.

beautiful aquarium and fish you have!
p.s. my fish hate floating pellets too

if you have a male and female there they will have a great breeding tank with all that rock.

looks good.

just keep in mind that you will have to upgrade fairly soon if you plan on keeping all the fish you presently have

great set up and good looking oscars.
