Two questions, Oops I mean three

1.I tried to get just Chaeto for my fuge, but there seems to be some grape caulerpa in there as well. They are all intertwined, so separating them would be a difficult task. I've heard that the caulerpa will go sexual on you and release their stuff into the tank unless lit 24 hours. What exactly does their "stuff" do to the tank. Will It just start growing everywhere or what?

2. some of my zoos have become very picky. I'm doing everything the same, but they just decided to not open very much. It's not all of them just one patch. I've read about nudis eating them and I have all kinds of bugs that seam to love that Rock, but I don't think they're nudis. Nudis are like slugs/snails right? The bugs in my tank look like copipods and amphipods. could these guys be disturbing them?

3. OK.. so Nudis. I've been told that nudis can't live in aquariums because they eat sponges. I've been told that certain nudis eat algae. And I've also been told that some nudis eat zoos. Can someone give me the low down on the different types or at least point me in the right direction? It's confusing hearing so many different things about the same bug.

Thanks Much and I hope everyone has a fantastic weekend.

1. I have never tried macro algae so I can't tell you for sure but what I have heard is that the plants practically disintegrate. I'm sure Jesse can answer a bit better

2. Have you checked all of your parameters? Could be something that's off. How's the temp, pH, lighting. How old are your bulbs?

3. Might as well give up on nudi's. Most aren't really suitable for an aquarium. There are species that will survive but I wouldn't chance it.

i don't think the caulerpa will pose an issue - just harvest it as it grows if it goes sexual it'll turn white and you can pull it then

zoas are finicky for some people - could be that you have nudis but they are not that hard to find. pull the colony out and check it out really well, also look for sundials. you could go ahead and dip it while you have it out in TMPCC or lugols.
if you don't find anything and it is just one colony then it is unlikely that it is a systemic problem like water q or bulbs - try placing it somewhere else in the tank. if it is multiple colonies then you may have a systemic problem and you need to figuer out whats wrong

avoid nudis period - not worth the trouble, they are all very specialized feeders and identifing to the species level and thus their specific requirements is very difficult.
the sea slug (also refered to as sea hare) is the algae eater you've probably heard about, but it gets quite large and i wouldn't want one of them ending up in a power head in my tank

1. I'll keep an eye on it. If it does go sexual and I don't catch it what could potentially happen to my tank?

2. My parameters are fine. My bulbs are under 2 months old. I'll try moving them but they were really happy at this location for a long time. If moving them doesn't help then I'll try a dip. They're on one of those branchy pieces of Rubble LR that I got so I might brake it up and glue them to a different rock.

3. OK maybe I'm thinking something is a nudi that isn't. you know the little hitchhikers that look like slugs, but they actually have a hard shell on their back. They come out at night and eat all the algae off the rocks and glass? Are they not nudis?

Thanks for the responses. :D

It's half way between that and a snail... No spikes but pretty close. I have a ton of them so if they're worth that wow. however I don't thank that's it.

Thanks for trying.

I read this in the link about abalone haliotos that trogdor posted.
though technically cold-water reef organisms they will last for several months in tropical conditions
I think it is pretty s***** to sell or to buy an organism that 'will last for several months'. If I put someone in an airless dungeon with a few crusts of bread and sips of water every other day they might last for several months too--what a life.

John nailed it. for some reason I thought those were called Nudibranches. Don't know where I got that from. while we're on the topic of Nudis.....



How big are these guys? I think I saw one on a new little frag that I got. The zoos wouldn't open up. I sucked it off with a turkey baster and they are opening up now but I couldn't tell what it was.

there are quite a few little clear colored bugs running around on them but they don't look anything like these guys. Is there another type of bug I need to worry about?

Very small, I'd guess about 1/8"- 1/4" MAX. You'll want to do a freshwater iodine drip.

The little clear bugs are probably copepods... harmless and beneficial.

I found a nudi hitchiker recently. I'd say he was nearer 0.5 than 0.25 inch long. I haven't seen it for a week or two so it may have succumbed or been eaten.

See that's what I'm talking about. What Kapenta Kid posted is also called a nudi correct? even though it appears to be very different than the dreaded zoanthid killer nudi. It's confusing.

nudis are by definition mollusks with exposed gills. they are "slug" like in that they have no shell of any type but are different because of the frilly exposed gills. if you look at both your picture and kapenta's you will see both of these features.
there are 1000's of species varying in size from nearly microscopic to inches. they all have very specific diets and many eat cnidarians, some only a specific coral. the nudi eating zoa looks like your picture although many report their color to match the zoas they are on. this is likely due to the fact that many also can incorperate the zoaxanthelea from the coral into their own tissue and thereby become photosynthetic in part themselves. the monti eating nudi ave. about 1/4 inch and all i have seen are white but some say they too can incorperate the algae from the monti into their tissue.
either way kill on sight - dip in freshwater, iodine or some other coral bath eggs can only be killed by brushing them off as the shell is impermeable to all dips we know of

I get it now. Thanks all. The picture I posted didn't originally look like a slug to me but after further review I now see it.

not so confusing anymore.

Thanks.
