color

Hi there, I am a researcher, and I need to know why do the color of fish change when they die? What are some of the scientific reasons? Thanks.

Thought this would be interesting to some people. This porcelain crab used to be completely red, then it turned pale and now it is marbled with both coloration. No clue why it is like this, my other red porcelain crab never changed colors.

Hey everyone, I’m thinking I want to pick out some new coral for my tank. I’m running a 75gallon with an ati 48” dimmable 8x54 t5 fixture. I really have no experience with sps corals and usually stick to lps and softies. I had been out of the hobby but recently got back in and so far have some...

Hello, This is a brand new item designed and fabricated to be 100% custom. The Stock Break Out Box can be an eye sore, especially if you take pride in your cable management. This break out box is completely customized by you. No one else on the internet has this option for a Neptune Apex Bob...

I am about to do the second wave of stocking in my 100 gallon tank and decided I'm going to make a bulk order of smaller fish on LIve Aquaria. I want to get a Longnose Hawkfish but when I went to add it to my cart I saw they offer two options the same size and the same price. The only difference...

We have two sleeper banded gobys. In our reef tank. We have noticed that every once in a while they have new spots or their colors are brighter. Today we noticed one of them now has a black line on his face, kind of like a mustache. Anyone have any insight on this?

I have two leopard wrasses 4 inch and 3 inch roughly. They both have the speckled female color pattern and look roughly the same except for size. They are active, eat well, and get along great. Usually they are within a foot of each other at any given time so they seem to prefer to swim and hunt...

Background Classification All of the hard corals fall under the order, Scleractinia, which falls under the subclass Hexacorallia. Hexacorallia is under the class, Anthozoa, within the phylum, Cnidaria. So, when we talk about SPS coral, some people say, "small polyp stony" coral, while others...

Hello, My anemones colors are not as colorful as these in this picture: This is what my anemones look like, they are colorful but not like these. My camera is not good so that has some to do with the colors in the picture, but they are not as colorful as these. Here is a picture of my...

Hi all, I'm almost ready to prep and pain the inside of my stand and starting thinking about paint color. My current plan is to use one the appliance-epoxy/Killz/RedGard recommendations and paint it white - it always looks so nice and clean and bright with a door-triggered LED. :) That said...

There are some crazy pictures of yellow and orange Acropora on the internet. Maybe I am colorblind but I have yet to see a true yellow Acropora in person. Online it is often hard to tell because everyone is using PS or camerafilters. So I'm talking >yellow to the eye under blue LED< no cheats...

hey guys, so I have this red table acro, it was red at first and then it started to turn green on the base. is this from having nutrient or low light? Alk 7.7 Cal 440 No3- 0.25-1.00 Po4- 0.25 I'm running AI Hydra 52hd about 8-9 inches above the water line. 1st and 2nd is picture is about 2...

I have 4 Hydra 26 HD's and I'm looking to see if anyone knows which colors affect certain colors of a coral and if raising or lowering that color enhances or reduces the coral color. I would like to get the most color "Pop" as I can. Thanks for any help.

I use ATI bulb on my 55 gallon and right now I'm using 2 blue+, 1 aquablue special, and 1 purple+. which ATI says is 10K-14K. I'm wondering if I should keep that and put a reef brite actinic blue lumi lite strip on id have that run 3 hours in the morning and 3 hours at night. or if I should do...

I have a 180 gallon mixed reef with mostly SPS. Lit by LED and flow by two Tunze 6105 powerheads and a Waveline DC-6000 return pump. My current params are 8 dKH Alk, 420 Ca, 1250 Mg, .10 P04, 5 NO3 I'd like to see if I can get more growth and color from my SPS. I also cant grow digitata...

Hey all - I have a Jack-O-Lantern Lepto that I've had for about 10 months now, the growth is outstanding- it's spreading like crazy...but the color isn't recognizable at a Jack-O-Lantern. No green eyes, no contrasting colors...it almost just looks like standard red/orange lepto's I've seen. Even...

Curious to see if anyone has photos of their progress with nutrient dosing. I see many threads of discussion of how to go about this but I have not seen too many discussions with photos of "improved coloration and growth" that many people claim. Please post your results. Thanks in advance!

First time here..... Hellow R2R I was wondering what are ideal Par values/numbers at top, mid & bottom for a mixed reef to include softies, LPS & SPS. All this Par, light intensity & color talk is confusing to me. :) I would like advice & recommendations on a 12 hr lighting schedule from dusk...

I'm scratching my head about an issue in my tank that's been going on for a while. My forrest fire digi is light pink-ish. It's lost the deep red it once had and I can't figure out why. Other pieces of acro and the general health of the tank seems fine and stable. The digi sticks out as the most...

My entire life I grew up in a muted world. I grew up in a brown brick house, didn't understand why street signs were so dull, and never understood why people were confused with my fascination with neon colors (neon pink being my favorite). Then one day while at the doctor's office it all made...

Hello everyone! I finally did it. I purchased a jawbreaker mushroom and I couldn't be happier. Lets call this an early Christmas present to myself. So currently my little beauty is bright orange and the size of a pencil eraser...I believe it is an original jawbreaker (orange, red, green) and...
