CBB did the job for me. It is a great fish that keeps my display aiptaisia free and featherduster free.

I have a file fish that cleaned up my tank fully, willing to part with him for $20.

Does anyone know where to get a Nudibranch in Edmonton?

My peppermint shrimp cleaned up my problem (I assume).

Keep an eye on that Xenia though! I hate it worse than aptasia! It grows like an invasive species.

If you have peppermint or cleaner shrimp and most wrasses they will often eat the bergia nudis. Not all peppermint shrimp will eat aptasia. Only certain species.

my peppermints havent touched the aptasia

but what i found that works is nitric acid

i tried the lemon juice and sure it kept it at bay for a day or two but always to return

i use standard issue general hydroponics ph down it has a ph or 3 so its pretty stong apply the same as lemon juice

hasnt hurt anything yet i did have a large aptasia on one of my clams and the clam wasnt bothered when i shot the aptasia full of nitric acid

I'm not sure what nitric acid dissociates as, but I'd guess not something you want in the tank. A better choice might be muriatic acid (diluted hydrochloric acid), as it dissociates as H and CL ions. Both harmless in the tank (within reason, don't use a pint of it :)) I've used a couple of small syringes at a time without affecting pH in a 155g tank.

edit: looked it up, N becomes NO3 in water....HNO3(aq) + H2O(l) --> H3O+(aq) + NO3-(aq)

Nitric acid is none destructive to plant cells used in low doses. When I use it it's a ml at a time. I have used it for years in horticulture. But u are right it may upset chemisty in water. Though I think it 200 gallon 1 ml is minor. I shall look into it

I threw 5 peppermints in my 20 gallon and within a week it's been cleaned up, not one aiptasia to be seen.

Peppermint's and Cbb non effective in my tank. Not severe but I will address it soon, Haven't tried nudi's but I think my wrasse's may take those out. Has anybody tries injecting them with "Joe's Juice"? Heard good + bad about it.
