I’ve had this candy cane Coral since March I think. It’s always been two heads. But for a while now one has always been bigger than the other and the other one won’t open up because there is no space. Also not sure how candy canes grow but I’ve had two heads since March which kinda sucks. Not...

Back in April I got this Gonipora and for months it's been enjoying life. About 1 week ago it stopped coming out and completely retracted. I noticed this brownish green spot on it, with a small tube coming out and what looks like whiskers growing all around the base of the coral. I saw this same...

yesterday i noticed 2 white spots that weren’t there before, could it be shedding?

Hi all.. I've had this candy cane for around 3 months now. Its not opening up well. Looks partially open. But sort of shrivelled up. My current parameters are as follows. I had given a frag from the same coral to a friend and its doing so much better in his tank. I don't exactly know...

Can someone help me narrow down possible causes for this? It’s been this way for about 4 days. It isn’t lighting and I have nothing to pick at it. Just conducted a water change last night and maybe it’s helped a touch? Can’t really be sure. Flow is mild. Could it be a pest or disease? (Sorry for...

I have a hammer coral with two branches. One head on each branch. One is fully extended and happy. The other - which receives equal light and similar flow, is only about 25% open. Up until two days ago they were both doing great. It had been there for at least 3 weeks without an issue. I’m new...

Hey everyone, My toadstools have been in this repeated shedding stage where they open not all the way for about a day, and then go back to being closed up for 1-2 weeks. It’s been like this for a few weeks now. Anyways, I read threads of people saying to increase flow in the tank for the...

I've had this torch about a month and it has been doing well up til now. It is usually extended a lot and swaying in the flow. But now, its open but its tentacles are really short. Its been like this for 4 days. I also have a frogspawn thats been acting similar, but it is splitting to grow a...

Hi, I have a 20 gallon tank and I got this meteor shower and a xenia about a week ago. My tank is relatively new (a little over a month) and my xenia is thriving but my cyphastrea wont open. I have it at the bottom of my tank and its been this brown color ever since I got it. Please help.
