if you do go cichlids stick with smaller ones around the 4" range(some get huge) some pretty suggestions would be sp44, christmas fulu, demasoni
rams are not that bad but some are very touchy. (electric blues, german glue, german gold are very touchy)
if you want plecos i would wait atleast 6 months to add them. stick with bristlenose or smaller dwarf plecos.
for bottom feeders i prefer the action and personality of cory cats. i especially like the panda cories.
