She is kinda right at adult in a year or so down the road they will fight and die.
for now you could add a school of tetras like black skirts or benous aries may be serpa tetras (tough tetras only)
A red tailed black shark might work just make sure its bigger than the jewels.
BTW what it a 33g tank never seen one before.
tanks with a 24"X12" foot print are one of these sizes 15g,20g,25g,30G
IMHO the Xtra tall 25 and 30g will not hold more fish than the shorter tanks.
So basicaly you need to stock for a 20 gallon tank.
You might want to think about switching to a african tank there are a lot more size appropriate fish to chose from.
Other wise start a SA dwarf tank.
To your defence buying a 55g tank to house your current stock is stupid they will be fine in your tank for a long time just dont add any more SA cichlids.
