My mom is a science teacher and has asked me to stock her tank again. Its a 15gal with lots of fake plants and a few decorum pieces. I've got my cichlids but I don't know much about community fish. I was thinking maybe some dwarf cories, shrimp, lyre tail danios and some male guppies. Like I said I know almost nothing about stocking a small community tank so I'll take any suggestions and pointers.
