So I was moving rocks around in my tank yesterday and found some hitchhikers. I'm pretty sure they are Majano Anemones but would appreciate it if someone who has actually seen these before could take a look. I have heard of people that keep these, and people who kill them asap - are there actually any pros to keeping thesa? I already see approximately 10 that are the size of my thumbnail - if I should get rid of these, can anyone tell me how? I've been lucky and pest free so far.... TIA!
