coral advice

I’ve been struggling with this colony for nearly 3 weeks now. About a month ago, these heads were beginning to split, which they did. But seem to have never recovered, and now I’m worrying about polyp fallout. When I feed about 2 days ago, the bottom head perked back up and looks half normal...

Will Xenia rob a tank of nutrients if allowed to grow out large? I read that in another post on another forum but that sounds like crap to me. Dad had a bunch in his 180 that just disappeared one day. Just trying to make sure these dudes won’t rob my tank of all nutrients and kill my Zoa collection.

I’m about to get some pulsing Xenia that’s loose. How the heck do I attach it to a plug or rock or whatever? Not sure about the size of the frag I’m getting.

Ok so I am not new to reefing. I’ve been doing this like 8 years. I am however new to leather corals. I’ve got a line on a great little toadstool leather frag I’m picking up Thursday. My question is do these dudes sting other corals? And what about the toxin they release into the water? Do I...

So I just watched the tidal gardens video on Duncan coral and their Duncan’s polyps were al stretched out and flowy like a torch coral. Does anyone know why mine looks like little stubs? Or how to make it look more opened up?

Hello I am new to the hobby i have a fluval evo 13.5 it has been running for 7 weeks i was wondering what types of testing methods incan use for the water and what i am aiming for to grow sps ect? I have attached a few pics of my current tank.

Hello I am looking to set up my fluval evo with a coral garden, i am more interested in corals than fish i owned a planted tropical tank a few years back and with the extra time on lockdown have decide to set up sat water nano tank. I will post pics of thank now 8 weeks after setting up . I...

Hello hello.. I've decided to take a stab at some montis recently, but im having some trouble. I added these two frags on Dec. 30th and they looked great. Now, the flesh is lightening up quite a bit, but the polyps are still extending nicely but the color is dull. Any help/tips would be...

One of my Zoa colonies won’t close not for some reason. I’ve blown food on them and touched a little with a sea squirt and they won’t close. They look like small umbrellas. Is this cause for concern?

So I’ve got a biocube 32 led coming after my old one cracked. I ordered two frag rocks that hold three plugs each to make zoa gardens. I want to know about this possible combination for the two rocks. I plan to make one bam bam/Rasta/GB packers+Utter chaos (combo plug). The second I plan to make...

Are the ceramic zoa frag stations safe for my reef and my Zoa? I’m thinking of getting two smaller ones so that my Zoa can grow out to big colonies and create sort of a small zoa garden.

Help, I bought too many frags during the JFox Sale live sale last week. The long story, please feel free to skip this part and go straight to the coral section- I upgraded from a 20g AOI to a used RSR 170 a few weeks ago. Cycled the tank in a few days using rock and media from the old tank...

Hey reefers. I’m looking at how much coral I can keep in my biocube. I currently have three zoa colonies about 15-20 heads a piece, a really small hammer with two heads, a set of candy canes with about 7 heads, one with two heads (bad shape), a set of paly grandis (three small heads) that I just...

I had this new coral, I don’t understand why it is not open up, all my water parameter are fine, what should I do? And I have move the coral to other side of tank so it would be by itself.

I’ve just picked up AF vitality, amino mix, and energy I have a 10 gallon tank and I can’t dose 1/4 a drop per the instructions could I dilute the product in aquarium water and pour it back into my sump (I’ve already heard you can’t with RODI water I was just wondering )

Hello all, I'm posting to get some guidance about my complete inability to keep any coral or invertebrates (reason I got into saltwater) I have had a 75 gal + 20 gal sump (filter sock, biologic media, skimmer and UV light) for over 1 year now. I have a pair of clown fish, blue tank, foxface...

I bought this coral from my LFS about a week ago and have some concerns about it I'm hoping someone could help me out. I was told this is an acan echinata correct me if I am wrong but there seems to be a spiky white growth in it that doesn't seem to be part of the coral because the flesh recedes...

So I swapped my evo to a waterbox cube 10, straight swap except changed to fresh sand bed. This was about a week ago. My Gsp have not opened at all and neither have my clove. I tried to change flow and have added a reduced % lighting via acclimation mode of my AI HD 16 but they remain shut. Ive...

I'm wondering how I should go about this and any help is greatly appreciated. My LFS (totally cool people) hooked me up a zoa frag with my order. 2 days later I'm seeing what I believe is aiptasia but I wanted to confirm with the more experienced. If it is indeed aiptasia I have read these are...

I’ve kept many corals over the years attempted an acro in a 100 gallon 1 year old tank a few years back and failed miserably just curious why they require an “established tank” as I haven’t really been able to find a good explanation other than stable parameters but if anyone that has long term...

Was looking at the tank today and noticed that my hammer coral skeleton is whitening. Anyone know what's going on?

Hi I got a new hammer coral two days ago and it hasn’t opened that much as you can in the photos. I don’t know if I’m overreacting yet or something wrong and it’s dying. I put it in one of my lowest flow in my tank my water parameters are: Salinity: 1.025 Nitrates: 2ppm Ammonia:0 Ph: 7.8...
