Good work! As Hulon stated...higher temp is neccesary for juvie cichla. Good to hear he got eating. Live black/tubifex worms is a good alternative to guppies. The fish hammer them and they can live for quite some time as long as you keep them clean. Since your feeding bloodworms you should start crushing pellets into the mix so they develop a taste for them. And gradually up the amount of pellets. Eventually they will be eating nothing but pellets.
