Hello there! My name is Jared and I have just finished setting up my freshwater tropical community tank equipped with a power filter and a nice adjustable heater. I do have one question though... The lady at pet smart told me to start out my tank with a few zebra danios. They have been in my tank for 2 days now and I was wondering how long it will take before I can add other fish I desire(glofish, guppies) Any advice would be great thanks!
