My mom wanted to buy some corals for my aquarium. So she went to the store and bought a colony of buttons and the worker asked her if she wanted anything more, then he pointed to a mushroom on a rock and said he could sell it for $15, the bad part is that the rock had aiptasias all over it. Now i'm trying to get rid of them ASAP! We ordered that thing to kill aiptasias. But well need to wait 1-2 weeks until it arrives, and the aiptasias are starting to spread! I know that one store is selling aiptasia eating snails, but i can't buy them because they cost about $96 and my emerald crab would probably eat them. I also think that peppermint shrimps eat little aiptasias, but as i said, i have a emerald crab in the tank, and for some reason i don't think it's a good idea to have them both in the tank. I searched for creatures who could eat the aiptasias, and then i found the aiptasia eating filefish (Acreichthys tomentosus). I could buy him, he's very cheap (only 3000-4000isk). But i am wondering if i could keep him. I know he wouldn't eat the emerald crab, but i am scared that the emerald crab could eat him. I am also worried about the coral nipping. According to live aquaria, he needs a minimum of 30 gallons, i have twice his demands, a 60 gallon so i know i could keep him.
