Wow there so tiny! You may have to repost a picture of them in a couple of month's there so small there still translucent. Very hard to tell at this size.
wow those are really small.. i would lean towards monos or ocellaris. make sure your water temp is 87+ for sure and pump them with live blood or black worms 3 times a day if possible at that size. these are in a very delicate stage right now, you have no idea and probably shouldn't have be sold at that size. with proper care you shouldnt have any problems.. welcome to the cichla family, dont let cichla take over your life and if you have any other questions this is the spot
lol geez they are small Sara..
Being in AUS im gonna say Mono or Ocell.. just do as b00st says and keep the temp high and plump them up with feeders.
re post pics once they get a little bigger.
