I have a 30 gallon. So far i have 2 tetras. And no there not neon tetras, they have the same body as a silver dollar except not as big and they one has a blue line at the top and the other has a yellow. 2 sunset gold guppies and 2 salt n peppers guppies. I would like to add platys or dwarf gouramis. Is that ok and how many should i add. The fish are about 7-8 months old and the tank is fine. Crystal clear is pH is rockin 
. Btw should i add an algae eater or no?
Sarah, i said my Tetras look like Silver Dollars there not actually silver dollars -.-
