As per the subject really.

I haven't got an Oscar yet. What would be suitable and can you add tank mates at a later stage or do they need to be added at the same time as the Oscar?

whenever you mix large cichlid together its alway a hit or miss kinda thing. all you can really do is add the tankmate and hope for the best. as for when to add a tankmate to an oscar tank i beleive that if they grow together the odds of them cohabitating long term increases but like i said you can never really tell.

as for what kind of tankmates to add to your oscar tank the list is long indeed. all i can suggest is do you research on what you think you might like and find out before hand if it can live with oscars and if your tank is large enough to accommodate it.

I've just seen a video of an Oscar tank with Silver Dollars in which looked very nice. I assume those are ok? Not sure how many would be a good number though.

Read through the recent topics man... there are at least a few threads on this subject... I have a Jack Dempsey with mine..

Sorry, I am reading through them but obviously the choice must depend upon how much free space is available in the tank and everyone has different sizes hence why I added it to the subject line

Sorry... Wasnt trying to bust your chops.. Just trying to help you out... What does 97UK gallon translate into for US gallons?

No worries It equates to 117 US gallons.

oh thats right(other thread... duh...)
You could get away with one Oscar and maybe 4-5 fish that were 5" maybe? I like that one on you tube with the silver dollars.. I also like Jack D's... Just make sure they are all about the same size to start with...

You could add 6 or 8 SD's. Make sure they wont fit into your oscars mouth or they will become lunch

I got 6 Silver Dollars with my O and they're an excelent addition.
Please check the info at the Tankmates section.
There's not much to add there.
I love my Silver Dollars and can say that they're a good help in tank maintenance.
They'll eat anything and quarrel with eachother over any food-particels in the water.
Any leftover will be eaten, al well as any Oscar Poo...
Very funny fish!

Are there any alternatives similar to silver dollars? I've been ringing round this morning and found a place that sells Oscars that will also take my snakeheads for me. They will only give me a credit note (£60) and don't stock silver dollars so I need a few alternatives in mind for when I go on Thursday.

So what do you guys reckon? If I can't get silver dollars what would look nice, shoal and obviously fit in the tank.
