    Need help. Nudibranch pest?

    I haven’t added any new rock or coral to my tank in months but today I noticed a bright yellow nudibranch about 2cm long moving across the back glass of my aquarium. The back of the tank is rarely cleaned so it wasn’t easy to photograph it through the algae buildup but here are the vest photos I...

    ID?

    What seems like clusters of tube/rod shaped eggs, open on one end, appeared quickly on open sand and a small spot on the base of a rock in shade within a couple square feet.. I thought nudibranchs but the mass is more of a wirey "neuron network" inside the cluster and could be a bunch of bugs...

    Is this a Vermetid snail?

    Hi guys, I noticed this little thing growing on the side of my cane cane coral frag. At first I hoped it was a new head, but after doing some research I think that it might be a Vermetid snail. However, while it has the same general shape of one, it does not seem to have the hard, tube-like...

    Cotton candy foam thing

    Recently, this pink/purple foam thing started overgrowing zoas in my zoa garden. What is it? What eats it or removes it aside from manual removal? Here are photos of it on zoa frags I removed to clean. I'm thinking it is a sponge. I have been removing the impacted rocks and frags and...

    Large Crab ID

    Hey guys. I just picked this guy up at my LFS. Guy said he was a pest hitchhiker so I bought it off him for a couple bucks. His body is probably about 3 inches wide not including the claws/legs. He's pretty big. He's munching on some octopus I just gave him. I bought it for my mantis shrimp...

    Any ID on this Nudibract

    I was dipping a few new frags today in Bayer and a second dip in Coral RX. I found this nudibract dead after the Bayer dip. Is there any way to ID the type? For those that don't dip new corals, this just goes to show why you ALWAYS should. This is a restart on a crashed tank (possibly due to...

    What is a good dipping schedule for a coral quarantine tank?

    Just researching the coral quarantine tank and thinking about the dipping schedule. I am looking at a fallow fishless, quarantine period of 76 days to rid the corals of the possibility of cysts hatching and infecting the fish in the display tank. Within that 76 days, how often, and with what...

    Hydroids?

    In the past month, I’ve been noticing more (what I think is hydroids) cropping up on my rock. Can anyone confirm? Also, noticed some tiny white specks on my glass, but it was hard to get a good picture. Literally look like tiny grains of sand on the glass. No distinguishing features that I...

    Possible Nudibranch. Good or bad?

    I found (What might be) a nudibranch in my tank, after lights out on one of my closed zoas. Photos and video from my phone. Hopefully you can shed some light on this critter! *fork to help focus camera!* Here is a video of it: Is it actually a nudibranch? Is it one to get rid of? Thanks!

    Ok, so after a couple days of searching, I have still not come to a solid determination as to what kind of inhabitants can be safely kept with Zoas & paly's . Other than the obvious zoa eating nudi's and obvious non-reef safe fish, are there any other certain fish / inverts to be warry of ? Or...
