I have a piece of large 'Green Mushroom Rock' which I believe looks very much like a Ricordea. It has been in my tank for over a year and thrived. However, I have noticed that over the last couple of days, one of the mushrooms has developed a number of brown patches on its skin.
Does anyone have any idea what could have caused this and what I should do?
I have a question about Xenia. I bought a lovely piece the other day and for the first week it was out fully. However then it started to close down and is now fully closed and has been for 4-5 days. I tested the water and my Ph was about 7.9 so I am slowly bringing this back up 8.2 / 8.4.
My question is - will this blip negatively affect the Xenia long term or will it back to its best once the Ph is re-aligned?
Hopefully, I am worrying about nothing but thought I would check. I was fragging a coral with a razor blade when I dropped the blade and it fell to the back of the tank. I would have to dismantle my reef to get it back, so I would only like to do this as a last resort.
I have googled the razor blade in question and it is made of rust resistant stainless steel. Should I be worried or just leave it be?
Hodgey - I have kept a six line wrasse for about 5 years now, great fish! But I did not get him to decimate a flatworm population, so I don't know if it will work.
On the subject of a mandarin, I know that a lot of people who keep them or similar fish that are hard to maintain (blue cheek gobies etc) keep an upturned plant pot somewhere behind the rock structure. If it has small holes in it - the copeopods can breed and enter in and out without being preyed upon. Never done it myself, but just a thought.............
