night

Hello all! I have had my RBTA for 5 days now. So far it has been great: he found a home on my rock & has had his foot anchored there since day 1. During the day (actinic & daylight cycle) the anemone looks beautiful; he has bubbles on his tips, has inflated tentacles, & is a deep beautiful...

Sorry, I know a picture would be preferred, but my critter is impossible to photograph. I have only seen it maybe 3 times. It is thread like and inches over my rocks. It is clear and smooth and appears to have a head. I would say an inch long and only a millimeter wide. It is free moving but...

What inverts (shrimp, crabs) are fun to watch and are out during the day? :blob:

there are little spots of green algae that is not filamentous, but glows at times at night! need help identifying this organism. It is a neon green at day.

Hey, i dont have any sort of moonlights on my tank and i dont want to shock my fish when all the lights turn on. What kind of moonlights from ebay or DIY ones are good. I also want to make sure that they aren't too bright but you can see somewhat clearly, Thanks

This worm comes out after the lights go off. Its shaped like a piece of spaghetti. About 1.5" of its body comes out of a small hole in the rock. Its NOT a bristle worm, I don't think. :) There is another smaller one that I've seen too. This video is not the best but you can see about .5' of...

well I have this purple rock in my tank but at night it looks like its on fire or something I really can't get a pic because I only can see it when the moon lights are on and the camera can't focus that much.. but some parts of the rock looks like its burning inside and it looks cool but weird...

should I leave moon lights on all night? or should I turn complete off all lights and give them some time in the dark?

Hello, I'm still fairly new to reef keeping. My question is: Can I put the skimmer on the same timer as my lights? The problem is the pump running the skimmer is a little too loud at night to the point where I can still hear it in my bedroom down the hall. Turning that one off got rid of all...

Why do corals shrink when the lights go off?

I have added my first stony corals the last month and notice they all shrink and withdraw at night. During the day they are expanded and eat well but they shrink down and look unhealthy at night. Is this normal? I'm talking about bubble coral, frogspawn, hammer, and an elegance coral. Actually...

Ok its amazing how the questions are pouring out of me concerning this tank. I have done nothing but read and read and read and I find alot of varied information online and love the feedback I get on this forum. Case in point I tried to google what a bubble coral should look like at night and...

I have plenty of creatures that only come out at night and I want to be able to check them out from time to time. I know some ppl have special lights just for this purpose but have no idea what they are or where to get them. Please let me know.

It is known that the pH of your tank will change from when the Lights are on, to when they are off... I know you can run a Light on your sump/refug. opposite time schedule of DT to help maintain pH... If you are running Lunar LED Lights at night, will this be sufficient enough to maintain...

I took some pics tonight of our new friend (still haven't named him yet) a fire goby and of one of our acans we have hope you guys like! So how do you fish/corals look like at night?

The other night I was looking at my tank a few hours after lights out. I noticed what I first thought to be aptasia. Upon closer inspection, it just doesn't look like any aptasia I've seen before. I'm thinking anemone but what kind? Good or bad? It only comes out when completely dark and...

theres only 2 blue led moon lights. its was hard to focus in complete darkness. my eye couldn't tell when the pic was clear.lol there are all the same settings 30sec shutter time and F stop 5.6 the last pic my bro turned on the room light for like a sec becasue he did not know i was i the...

Quick question, lights on or off at night?
