Only stn on one frag, yellow tips.

Curious if I have a bunch of sps but only one of them is stn from the base, would you do anything about it? Or is it better to just leave it and hope for the best for a comeback? Not sure if the aiptasia is stinging it either?

its been in the tank for a month plus and noticed it got pretty pale. I figured it was due to my high lighting since I have two radion g4 xr30w pros over a mr aqua 22 gallon. So the only thing I’ve changed recently is the light intensity since I was running the ab + at 30% which I figured was just too much since all my corals were looking a little pale. Since I raising the light and lowering to 20% I noticed more polyp extension on everything else however I’m not sure if the stn or maybe even rtn happened over the last day or it’s been slowly happening with the yellow tip.

other parameters are all stable. Not enough sps for swings in the alk.

would you says it’s the lighting or the aiptasia?

Do you have a pic of the tank (not under blue light, but daylight so we can see the details of the animals in question)?

Here is a photo of it under no light

Possibly lighting and low nutrients. That tissue looks pretty dry to me. What are your current parameters? Alk, N & P being the most important to me, followed by salinity and temp. How old is the tank and did you use dry rock?

-Salinity 1.026
-Temp 78 but it does slowly swing 2 degrees between day time and night time
-alk 8.7
-nitrate not sure
-po4 .03

rock is years old and so is the tank came live from Florida. Like I said all my other sps are great.

Personally, I like to keep N & P higher when possible. If it’s just that single piece that’s not doing well, then I wouldn’t change anything. How many fish and how often are you feeding them?

I feed a ton. Frozen, pellets and live. Twice a day. It’s a 22 gallon sumpless. Currently housing a yellow coris wrasse, two full-size clowns, and cleaner shrimp. I seem trouble getting high po4 and I don’t want to dose anything to raise it since things can go wrong quickly in such a small tank. Maybe I’ll lower alk to around 8

You may want to feed the whole tank, as twice daily isn’t a ton. Unless they’re huge portions? Which isn’t good. I would consider using phyto, reef roids (or similar coral food) on top of your regular feedings. You have very little bio load/mass, so there’s nothing that’s contributing to feeding the corals. Corals need to eat, even sps, that’s why they have polyps, so if you can’t help provide more food, then you need to introduce more nitrogen and phosphorus to the tank. Add some snails to help with algae, which in turn, feed the corals.
