I have an empty 30 gallon that I've been wanting to set up with the best looking arrangement possible. The setup I've been thinking of is 3 angels, a group of blood red swordtails, and a pair of blue rams or keyholes. I haven't bought anything yet and I've never owned these particular fish types, so I thought I'd ask around to see what more experienced people think. If this won't work, then what are your ideas for a great looking and compatible combination? Thanks!
