I have a 55 gallon tank that has been cycled for 2 months now. I'm keeping it pretty simple, nothing extravagant. I have 2 clowns, a pajama cardinal, and a green chromis. I only plan on getting 2 more fish, and then I want to start getting corals. I do have a cleaner shrimp, a few snails, an emerald crab, and 3 hermits. Up to this point I haven't quarantined anything, and so far everything's going good, although I know it's risky. I've just started researching corals, and it makes me a little nervous to just stick those in the tank without going through some sort of quarantine. I'm also concerned that at some point, 1 of my little buddies may have an issue that may need to be quarantined. I don't really have a place that I could put a big tank, and was thinking about just getting a 5 gallon tank, but thought that may be just a tad small. Any thoughts? Thanks.
