So years ago i started a saltwater tank that was 10 gallons and it did not go well because I was trying to be cheap which doesn't always work in fish keeping. My 29 gallon tank is almost empty and I was considering jumping into saltwater fish again. This time i want to do everything right the first time. I used to be quite knowledgeable on saltwater fish but again it's been a while. Basically I am looking at two options. i want to either do a FOWLR community tank of some sort(crabs, shrimp, small fish, etc.) or if it's possible maybe a single predatory fish? Suggestions on both combinations. Looking for fish that are interesting to watch more so for the first option. Since i am not doing corals will i still need a protein skimmer and "special" lighting? the filters will be an aquaclear 50 and an xp2 canister filter. So I think that's it for now comments?
