Hi, I have a 6 and a 12 gallon JBJ Nano Cube Reefs. I bought a moonlight fix from nanotuners so the lights are on timers. For both tanks, one of the LED night lights has gone out. Nanotuners doesn't sell those. Where can I get replacements? Thanks.

My 14-month-old nano cube reef had one Oscellaris clownfish and one regular firefish in it. The firefish vanished a few weeks ago, presumably died among the live rock and was consumed. Should I get another fish? I was thinking about a purple firefish. I am a bit worried that the clownfish...

My 12 gallon nano cube reef is 14 months old. I have not added any animals in 8 months. I was surprised to still find a new species in my tank this morning, especially one this big. I am not sure what it is. It is worm-like, very soft. The body can range from one to three inches depending...

I have a 6 and a 12 gallon nano cube. The 12 gallon's fans have always been fine. The 6 gallon's made racket and died when I got it new so I got the manufacturer to send me a new lid. In the last month, the fans are making a ton of noise. You can hear is over the noise of those two tanks and...

I got a pink dwarf Hawaiian feather duster for my 12 gallon tank today. One of my first animals was a tiny feather duster that came with my first coral. It was a hitchhiker. I now have Dusty, a bigger feather duster. His tube is about 4" long and feathers open to 1". He's been opening and...

I just got a green clown goby today. He didn't look too good in the bag (mailed from Live Aquaria) but seems to be mostly recovering now. The SG in that bag was only 1.021. Anyway, his tummy looks awfully sunken. Is that normal for clown gobies since they wedge in corals? He likes the fake...

I've had my 12 gallon nano cube tank for almost 5 months now. Today, after doing the weekly maintenance, the pump stopped moving water about 5 minutes after I turned it back on. I tried another outlet and then took the pump out and took it apart. Well, the drive shaft for the magnet is metal...

A few days ago, I noticed a few intense red spots on the live rock, pretty but unusual. I couldn't figure out what they were. They never seemed to move. I haven't added anything new to the tank in a few months. I finally saw one move today. I guess they are the dreaded red flatworms...

I got a 6 gallon nano cube on 8/8/08. Yesterday, when I got home, the fans were buzzy abnormally. Today, when the timers turned on my 4 tanks, the 6 gallon was dark (nothing, no flickers or anything from the fluorescents). The fans still run, and if I turn the switch, the LED night lights...

I got my first saltwater tank a few months back, a 12 gallon nano cube. I had a rough start but things are going great now (I'm an expert! Yeah, right!). So great, that I want more (bad me, bad! I have no room or time for another tank.). In that time, I've pulled an emerald mithrax crab...

I thought the surprises in my 3-month-old 12 gallon nano reef were over but I still find new animals! A month ago, I moved an Emerald mithrax crab out of there and put him in a 3 gallon tank because the star polyps were always closed while he picked at them. Today, I got home and WHAT? A CRAB...

I'm always finding new stuff in my tank! I now have found 5 little feather duster worms, 1 bristleworm, 1 little snail (that I didn't buy, who knows what that is but he sure moves fast!), and some lovely planaria (I'm being sarcastic of course; as long as they don't overbreed, they should be...

I got some new corals and snails last Monday for my 12 gallon nano. The guy told me that for my algae problem, I should get an Emerald mythrax crab. I asked him if they'd eat my other animals. He assured me that he was reef safe. Well, half my tank is full of algae but the crab just sat in...

My "12 gallon nano cube" has one fish in it, a regular Ocellaris clownfish. He's been in there two weeks now. The day I got him, I got a black and white version too, for $50. Six days later, the regular one finished off the fancy one after slamming him one too many times. I had been told...

A few weeks ago, I got my first nano reef animals - 6 hermit crabs and 7 snails of 3 species. The hermits survived and did well. All the snails died instantly despite an hour of drip acclimation. The store said it was because the salinity was too low (1.023, now it's 1.0245). I also brought...

I got a new test kit for phosphate today. My 12 gallon nano cube is a month old and had had 6 tiny hermit crabs (only animals so far) for almost two weeks. I've gotten pH, alkalinity, and salinity under control and come to find there's a phosphate problem. It's 2.5 ppm in the tank and 1 ppm...

Hi, I will be adding fish to my 12 gallon nano cube sometime in the next month. I planned to have 3 total fish eventually - a regular Oscellaris clownfish, one black and white one, and a firefish. Then, I read in my book that the Hector's Goby is great at sifting sand and eating hair algae...

I just set up my new "12 gallon" nano cube. I put in 7 gallons of saltwater and 8 pounds of live sand. The tank is totally full. So, how is it 12 gallons? I'm a chemist and measured very accurately. It makes a HUGE difference in how much of various things to add if the tank is 6 gallons in...

I'm sort of an expert on all sorts of animals, freshwater aquarium animals, and ponds but I've never had a saltwater tank. I've always been too petrified. Yet, I'm a chemist so the chemistry part of it shouldn't be scaring me off. I just don't want to be killing lots of rare animals. I...
