No problem, I love to help new reefers! one more thing keep in mind that you are limited in fish that you can get. I actually started a 3.5-gallon SPS dominated tank a couple of days ago. I do have a fish in it that really good for tanks that sized. it called a spiny head blenny and eats little foods called daphnia. those fish would be great for a tank that sized. The fish gets a maximum size of 1.1 inches and is not aggressive. I would suggest these to a new reefer due to how easy they are to keep. However they do have small mouths so small foods are needed (daphnia, baby brine shrimp). Good luck and happy reefing!
