Brutal Sunday

[kien]

I had an infestation a few months back. I started by sucking them up one by one with a turkey baster each time I saw one on the zoos. They are much easier to spot at night when the lights are out as you can shine an LED flashlight onto them and they will fluoresce (since they take on the zoozanthellae of the zoa that they consume). Anyway, that made a dent in their numbers but I would still see the odd one now and again. I read a list of wrasses that will hunt them and ended up getting a leopard wrasse (they look cool to boot). Since putting the wrasse in I have not seen a single nudibranch. There are other wrasses that will possibly hunt them like the canary wrasse, six line wrasse, green wrasse, melanarus wrasse, etc.

I was thinking about getting a wrasse, however another question popped into my head. I've heard that some wrasses are aggressive towards other like body fishes and I have a blue assessor that had that same torpedo like shape. I would hate to add something that would constantly bully the assessor around.

I think in general most of the reef safe wrasses are pretty peaceful, like the fairy wrasses, canary wrasse, melanarus wrasse, leopard wrasse. There are exceptions though, like the reef safe 6 line wrasse can be pretty aggressive. Most if not all of the non-reef safe wrasse are the ones to watch out for, they are quite territorial and aggressive. Lunare, Banana, Pink Face/five stripe, sunset, Red Coris, etc.

I can only speak from personal experience here as I have a Solar Fairy wrasse, Leopard Wrasse, Canary Wrasse and Melanarus wrasse that all get along and show no signs of aggression towards any fish.

I have a blue assessor and a six line with no probs.

Just a tip. When I buy my zoas frags etc I add a few drops of Flatworm Exit to the bag the zoas are in. mix it up and let stand for 10-15 minutes and any nudi,flatworms,fire worms,small bugs ,snails ....ok basically anything is done for, but without any effect to the zoas at all. Give it a rinse with some aquarium water and your done. As for eggs I find using a soft tooth brush takes the egg sacks off the zoa in one swoop of the brush.

I have switched to this method of nudi removal as I have lost too many colonies to freshwater dipping. It works well but I find it stresses the zoas out in my experience anyway. If you are going to fresh water dip make sure you buffer the water as well.
