I don't really like the look of the smiling acaras... I would rather have an angel fish. I don't want to have a pair of dwarf cichlids with corys, because I have read a few reports where the dwarf cichlids rip the corys to shreads during breeding. Even though it isn't the most common thing in the world, I don't want to risk it. So that is why I am going with a lone instead of a pair of dwarf cichlids. I also prefer the look of Cockatoo apisto to the look of the Bolovian rams. Picky, I know.
So here is what I am planning so far.
1 Angel fish
1 Cockatoo Apisto
10 Larger tetras
8 Corys
1 Male Swordtail
I am messing around with Aqadvisor. I have figured out that not all of their infoormation is accurate. But, I'm not sure on this part. It says that the APistogramma Cacatuoides is too small to co-exist with the angel fish. I have read where they will work out fine. But, I'm not sure about the sword tail. It says that I should have atleast 3 swordtails. I only want males so I won't have to deal with fry. So could I keep a lone male okay?
I'm not trying to contridict what Wills said, but aqadvisor does not state any warnings when I add a Keyhole to the tank stocking. Does anyone else have any opinions on a lone keyhole in this tank?
Here is the link to what I am looking at. You can take a look at it, and have a go at messing around with it yourself.

EDIT: My LFS usually varies on what kind of apisto that they have in stock, but most of the time they have Cockatoo Apisto. They also usually have Panduros. It usually depends on what they order. They seem to vary the apisto that they order.
