Sorry i should have said that the 4ft tank will be to house Oscar. And when i get the tank i will buy another oscar to go with the one i have.Even with the four footer (which im not sure how many gallons that is) you still may have some problems with the oscar and angels. It would problebly benefit the whole tank if the oscar was sold or given away. And be careful, the silver dollars may freighten the angelfish with there fast movements and skitishness. Other then that it'll be fine with the 4ft, or maybe even the 3ft if I knew how many gallon that was![]()
What kind of plecs are they? If they're commons, the min tank they should be in is 4ft x 18" x 18", and that would be for one - preferably bigger for two as big plecs (they can and do get to 12-18") can be quite territorial. And two oscars would need an absolute minimum of 75g (which would be the 4ft x 18" x 18", but most oscar owners would recommend 90-100g min as a better size) with no companions - with two plecs, you'd be looking at at much bigger (say 130g+) - but then you could get away with a shoal of silver dollars too (maybe 6-7).
If they are commons, I'd rehome one, and put one in with one oscar in a 75g/4ft x 18" x 18". If you went for a 4 x 2 x 2ft, you might get away with two oscars provided they were a bonded pair, but still only one plec. You might be able to squeeze in the silver dollars then too. It'd mean a lot of tank maintenance though - possibly twice weekly water changes (not your little 10% ones either, more like 30%), and some really good filtration. Many oscar owners recommend filtering for the tank size x 10 (ie if your tank is 75g - get filtration that will cover for a tank up to 750g!), but I think that might be a bit OTT. I'd certainly get enough to cover double the tank size though at least.
Good luck - post more piccies please - especially of those plecs![]()
