Should I place coral a bit higher?

[Icryhard]

Probably an odd question, but my coral seems to be growing. However one head seems to be more (or almost) in the sand. I assume not receiving light or being near/in sand will kill it? So should I put it on a rock?

If something is growing and looks ok, I tend to leave it. As long as the heads are not IN the sand they should be fine.
What you DON'T want to do is take something from a place it's happy in. I used to have a HUGE frogspawn colony for like 10 years and several heads touched the sand but were always fine.

Is that an apitasia colony next to it?

Unfortunately it is. As much as I am fighting against it, it's not becoming less. I sometimes use lemon juice to squirt some away, but it's a lost battle. Right now there is a Monacanthidae in the tank and I am hoping it'll eat them, but it rather seems to be a shy fish which comes out at night. I tried 3 nudis (yes I know, not enough for a 120 G tank, but I wasn't sure whether someone would attack or kill them so didnt want to invest too much) and I haven't seen them do much. I honestly think they were killed by a fish or coral bandid shrimp

Even if they're being covered by another head and they do not receive light?

If that bothers you, you could always tilt it up a bit so the bottom gets the same amount of light as the others.

Is that whole hammer colony one piece or is the right one separate from the left one?

If it is separate I would take it and mount it on a piece of rubble to elevate it.

I'm constantly trimming and remounting heads of my hammers. One was growing slow and seemed to be annoying the one next to it. I removed it and broke it up, remounted onto rubble, and moved it to a place where it could literally stretch its arms.

Another hammer I have tends to overgrow the lower heads which eventually die off.

The most success I had with Aiptasia was peppermint shrimp. I would move the corals away from them.

Okay, I'll try that. Any downsides to peppermint shrimps (in your personal experience?). I've read they're hit or miss and could attack corals?
