Suitable Additions

[Linchy]

I am in the process of setting up a new Juwel Rekford 800 aqaurium, 110L.
I am moving an Oscar and 2 gourmies into the tank.
Being a relative novice of fish compatability I am after advice as to what fish would be suitable to add to this environment.
I hear Oscars can be very territorial and agressive towards fish in their 'space', but I have a larger Oscar in another tank who is very docile?
I was thinking along the lines of a Red Tailed Black Shark or a Parrot, but this is only because I currently have them and so I am fairly ignorant to other options!
Any advice would be appreciated!
Also........Sand or Gravel?!
Thanks in advance!

It's your choice on the substrate. The Oscar will out grow the 110L in a matter of months. Depending on the species of gourami, they could do the same. Neither the parrot or shark are good for a tank that size. I would start over with small fish that stay small. Such as tetras and dwarf cichlids, or some of the rasboras, livebearers, not mollies.

I appreciate what your saying but the Oscar and gourmies are being transferred in so I need fish that won't just end up as an expensive treat for a hungry Oscar? When they outgrow a tank I move them on but until then I have to transfer them unfortunately.
