So a few months ago I was taking pics of some of my stuff and found in a pic I took with a macro lens that a purple cap that had never really taken off in my tank had little black dots the size of pin heads on it (pic below). From there I searched and found a couple posts here and there that said there were small black bugs that seemed to like montis.
I inspected my other montis and moved a few digis to the front of my tank so I could keep an eye on them. I dipped the purple cap in TMPCC and used a baster to blow the little black bugs off. Several weeks later I *think* I see them on two digis.
Last night I looked around and searched for several hours and not one post I read seemed to have any real suggestions on what they were, nor how to get rid of them. There were a few suggestions about interceptor, but nearly every time it was suggested some one else would pop in and say that it didn't work for them. A few other suggestions were made, but most said that the coral nearly died or did die.
There corals have been in my tank for 8 months to a year and these three that seem affected have never really grown. I do have a green and red cap that are like weeds and I don't see any on them at all. So I do think they are coral specific on what they chose to inhabit. None of the affected corals are *covered* in these things, there are just a few here and there.
Does anyone have any suggestions? I was planning on taking out the three affected corals, purple cap, yellow digi and a red digi (all from the same supplier) and do another TMPCC dip today.
