in my rio 240 i have 2 smallish angels, 5 mollies, 3 swordtails,2 guppys, 2 corys and a small plec
my tank is sort of an rspca tank with fish that i took on from ppl i knew as they were selling their tank, fish was getting bullied etc.
need to sort the numbers out and decide what i want to keep
Ok, if you want to go for the rams I'd say that you should rehome mollies, swordtails and guppies, maybe keep them in another tank.
Get at least four more corys of the same species as they are shoaling fish. If you can get their numbers to 10 that would be great.
Get another couple of angels. They too are group fish, but I wouldn't get any more, as you'd be pushing it.
In such a setup I believe you'd be able to have six rams.
Remember, they are soft water fish, so start doing water changes (after removing the livebearers) with pure RO water until you reach the desired hardness, don't hurry it, be patient, it may take up to seven or eight water changes, depending on your schedule. The rams are common fish, and they will be there at the store waiting for you.
If your tank planted?
