question

I’ve noticed a branching like pattern coming up from my sand bed on the glass that looks like little hairs once in a while the past few months. Looking closer they seem to be 1-2cm single worms moving in a group like an ant colony. They don’t seem to mess with any coral or my pod population but...

Hello all! On March 18, 2025, I moved my reef from my 40g cube into a 75g aquarium. Move was successful, checked water parameters at two fish stores and was given the OK, sand didnt mess water up and no heavy metals or anything bad. Using a canister filter with mostly sponge, some charcoal and...

As I get older, I’m starting to struggle hand brushing pumps, power heads, and other aquarium equipment. I’ve been thinking of getting a cheap, small dishwashing machine (new) and using it solely for my aquarium equipment. Nothing would ever be washed in it except aquarium hardware that doesn’t...

I got a plating montipora about a month ago. It has grown a little to my eye. I am just wondering if this monti looks healthy? It doesn’t seem that the polyps are as open as they were the first few days in the tank. If not, what could be wrong? Parameters are good. All other corals are happy...

I saw this fish at the Baltimore aquarium and figure it’s some type of wrasse. Its gorgeous! I’d love to know what kind of fish it is and how to keep one.

I’m in love with the water box 125 and/or 155 frag tank. I have a 2 year old generic 100 gallon in my office at work that’s been running well. It helps kids focus during some hard counseling and offers a distractions for kids when a parent may be there in counseling with me. So it’s fun and...

I recently had an outbreak of brown jelly disease (BJD) on a wall frogspawn i purchased back in November. Long story short, i didn't know it was a wall when i bought it otherwise I wouldn't have because I know they have low success rates and don't ship well. When it arrived, it had some sever...

Sorry for the crappy photo quality, looks like small plate like algae that is growing all over a rock. Also small strands coming off of it. Thanks for any help!

Found this guy in my nano tank. Is it an aiptasia or some other type of pest anemone? Will berghias eat it? The polyp is about the size of a dime and the markings are a brighter white in person. Thanks everyone for the help.

My lawnmower blenny has been breathing strangely recently and as of today has started breathing with his mouth open.sometimes the breathing has been fast and other times it’s slow and hard. Tankmates are a single fire fish goby and a pistol shrimp that were added at the same time with the...

Tl;dr: I have acquired a new 15 gallon aquarium, this will be replacing a 5 gallon aquarium, but i my only option is a hot swap rather than letting the new tank cycle on its own. Any advice to make this go easier? I'm also curious about media, as it stands in the old tank I've just got a pile...

Hello everyone. I am new to the hobby and have been doing a lot of reading and video watching and im still not 100% confident in my setup, and I have some questions. I was recently given a 40 gallon cube tank with about 50 pounds of live sand and some dirty water and maybe 10 pounds of cycled...

As you can Imagine I inherited this tank and all its content, and learning as I go. There are several piece like these, can someone tell me what they are? TYIA!

I’m not sure if this exists somewhere in the forum or how other people have learned this but I’m having a harder time picking it up. How do people know what a coral will look like when more grown out? Being new to the hobby I find a lot of coral that look really good, and that my tank can meet...

These little white coils are growing all over my base rocks and my back glass, any idea what they are? I’ve tried picking them off but they won’t budge.

Hello everyone i was looking into buying two wavemakers for my red sea reefer g2+ 200 and i was wondering if i should buy 2 jecod-dlw 10's or 2 jecod-dlw 20's. I was wondering if the 20 was too powerful for my 50 gallon tank? Greets

Conducting a survey!! Based on your experience what is your sps and lps coral success rate on the first 1 year of a tank preferably to more sensitive ones ( torches, acros etc) (dead rock, starting from scratch). Also if you would like to comment what after how many months you find you tank...

Could you house a Klein's butterfly in a macroalgae tank? I am aware that they aren't coral safe, but I cannot find any info on them with Macros.

I know this is a pretty odd question but I've been looking into the Ruby Scats lately and found very little beyond the basics. I know they get pretty big, do better in groups, and do tend to eat quite a bit of greens, but I was wondering if you could do a few in a macro tank? I've noticed that...

Long story short. When I started up my tank, I added too much ammonia because I was misreading my API test kits. I have since switched to Red Sea. Ammonia was sky high, I did about a 1/3 water change. Went away for a week. Came back, ammonia was even higher, Red Sea test came back blue, and...

So I just started up my new tank. As a source of bacteria, I used Ocean Direct Live Sand and Dr. Tim's One and Only for Reef tanks. For ammonia, I used Dr. Tim's Ammonium Chloride. Tank is filled with saltwater at 1.025 specific gravity. Original water is RODI. I added the bacteria and ammonium...
