Adding a cardinal fish?

[pgreco]

I have a ten gallon with a biowheel and a skilter that i have had for over a year. I currently have a sebae clown and a purple and yellow pseudo.
i would like to add a cardinalfish.
Any thoughts?

i think by adding the cardinal you may be pushing the limits on your 10g. smaller tanks are not as forgiving as larger ones and will be much harder to maintain if a problem arises.
