I have a 10g with 3 confirmed aiptasia anemones, possibly more. I have read of several ways to deal with them but i would like some advise. A peppermint shrimp is often recommended but with such a small tank im sceptical and i dont know if my not so LFS would take the shrimp back if it did fix my problem. My favorite "fix" is injecting with lemon juice. That way it dies but im not taking another creature from the wild but ive read that you need a rather large anemone for this to work and thankfully mine arent very large yet. If anyone has any ideas that would be invert safe and better than me trying to stab rather small anemones i would appreciate it.
