that sure looks like aipstasia. good luck. I've seen the sediment of Kalkwasser work when placed on the aipstasia. Tried it myself, and no luck. I've also heard that Joe's Juice is good for eradicating aipstasia. like i said, good luck. Mine haven't completely taken over the tank yet, it's been a month since I noticed them. They have grown larger.
joes juice works very well, and easy to use. is that the only one? if so, try to get rid of it asap. also, pepermint shrimp usually work well, and will get the ones that you may miss with another method.
Yup - that's aiptasia. I bought some Joe's Juice a few months ago and I've had good luck with it on my aiptasia and majanos. Kalk paste or boiling water might work for you...if not, give Joe's Juice a try.
I found around 8 aptasia on some rock I bought from my lfs. None were visible at the time of the purchase. I picked up 6 peppermint shrimp and luckily they took care of the problem. I was told if they didn't take care of the problem, to inject them with kalkwasser (sp?). Good luck.
If you want something that works everytime, try lemon juice. You will need a syringe that you can get from a pharmacy (same one diabetics use). Stick the aptasia with the syringe and dose the with about 1cc maybe less if it is a small one. The aptasia will draw up into itself which serves to concentrate the lemon juice in it even more. In 2-3 days the aptasia will be dead and it will not affect anything else in the tank. When you go to get the syringe be prepared to answer a few questions about what you want it for.
Yep, they look a lot like aiptasia. Mine are slightly smaller than aiptasia and have little bubbles on the end of the tentacles...similar to a bubble-tip anemone.
Hate to be the party pooper but I dont think that is aiptasia. Looks more like heteractis sp. Which would classify this as one of the many "rock" anemones. The tentacles are offset from each other creating multiple rows which in Aiptasia, this is not so present. The tentacles are also thicker and the base is not typicly extended as is the case with Aiptasia.
