I have one that split and now I have 2 and I don't think they are hard to take care of, but do some research what I read said you are doing good to keep them alive for more than 2 years, and great if you can keep them for more than 5. Also I've seen a lot of people say not to get one unless your tank is at least a year old. I did not know that and got mine when my tank was young. So far so good but I have only had them a little while. Odds are against me what I also read said your clowns will take care of it if they host. I try to feed mine silversides too but usually my cleaner shrimp steal them.
