So I've always been interested in saltwater but don't have a big tank on hand to get fully into it. I do however have a 2.5 gallon tank sitting empty. This would be my first saltwater tank I have about 15 years of freshwater experience ( yes I know two totally things). I was really just looking into doing a mini coral tank I don't know of fish or critters that would survive in that small of a tank.( If there is any please inform). Just looking for opinions and advice not looking to be screamed at about it. I've seen it on YouTube and read some articles and I want real feedback from all of you guys.
