Our 150 gallon reef tank is super healthy, but several months ago we noticed the appearance of some teeny tiny tube worms. At least that is what they look like. Long tubes running along the rock and itsy bitsy feather duster tops. "How cute!" we exclaimed, and they are! Trouble is, that rock is...

When Hurricane Ike came through in Sept, all of the animals in my 50 gallon tank got transferred to my Mom's 150 gallon tank (she had power, i didn't, and we had to act fast or lose them all. The battery backup I spent $75 on lasted about 2 hours and we were without power 5 days ) Once...

My Mom's tank has one rock that is just covered in teeny tiny tube worms - at least that is what they look like. They have loooooong grayish-white tubes that run over the rock or emerge from holes in the rock, and tiny feather-dusterish heads about the size of a pencil eraser. The feathers are a...

I have been in the hobby over a year now, but I have 3 new questions! 1. How do I know if an aquarium decoration is safe for saltwater? If I bought it for a freshwater tank ears ago, should I assume it is NOT saltwater safe? Or is there a way to tell? 2. I added a firefish to my tank 2 days ago...

I have a 48 gallon hexagonal FOWLR tank (closed system), and several months ago I lost all of my fish due to a malfunctioning powerhead. I put in a GFCI outlet, and a grounding probe, and have been rebuilding my tank. My inverts survived the shock. I have a purple lobster, a chocolate chip...

My mom bought a beautiful Jasmine/Fox coral for her 150 gallon reef tank. It did great for several weeks, but now it seems to be slowly shrinking/dying. Anyone have any tips for this type of coral?

I have an infestation of spionid worms in my 50-gallon hex FOWLR tank. Now let me say I KNOW they are harmless, and I KNOW they eat detritus, and I know that one way to try and keep the population under control is to cut back my feeding. Knowing all of this, I still want to know if something...

I had a tragedy this weekend. On Friday I came home from work as usual, fed the tank, everything looked fine. Got a small shock when I touched the light fixture, but from time to time I get an electrical shock when I am dealing with the tank, and have been told that this is very normal, due to...

Ok, I bought a sixline wrasse for my 50 gallon tank. I need him, because I have an abundance of worms and although I know worms can clean detritus they are getting a bit too abundant for me to stomach. Anyhow - I have my new wrasse in a floating isolation box right now because when I put him in...

Ok there is just weird, weird stuff in my 50 gallon hex tank (FOWLR, closed system). I posted awhile back about the uncontrolled "sponge growth" on my live rock. Well, I took the LR out and scrubed off as much of it as I could but it is coming back (see 1st pic below). It just coats. I also...

Minor damage to front dorsal fin and left ventral fin Suspects: Purple...

Just a bit of advice to always research a species before you buy it! My mom was talked into buying a pair of harlequin shrimp this weekend, was told by the LFS dude that they could be fed brine shrimp. The little suckers were $20 apiece! But they are also way cool looking, so she bought them. I...

My mom's sump/refugium has loads of copepods - they are very visible to the eye, and there are swarms of them. Are copepods able to get from the sump up into the tank on their own, or do we need to manually transfer some from the sump to the main tank? I am asking because eventually she wants to...

My Mom's Diamond Watchman Goby, Bob, has suddenly gone missing. He has always been really active, out in front, burrowing all over the place. Is it possible that he burrowed under a rock enough to cause the rock to shift and crush him? Or could he just be hiding? The tank was cleaned a couple...

Hiya My Mom has a new tank that is reaching the end of its cycle (ammonia spike is over, nitrates are beginning to fall). She had a diatom bloom in her sump last week and this week it is being taken over by hair algae - I had no idea the stuff could grow that fast! Every day there is more of...

Hi again :) My Mom just got a 75 gallon saltwater tank - it is about 3 weeks old but 25% of the water came from an established tank (the guy who set it up says this will help it cycle faster). Anyhow, she has developed bad brown algae bloom in her sump underneath the tank (the tank itself is...

I have a FOWLR tank - 55 hex - and I have a really aggressive growth of sponge on my live rock. It started off small - a little here, a little there, but it is spreading and growing especially in the "undersides" and "backsides" of the LR, where not much light goes (I have cheap lights - this...

A strange thing has happened to one of my feather dusters - the head appears to have detatched. I have not removed it from the tank because I thought maybe it is still alive but I do not see any "worm" part at all - it appears to be only the feather part. It is not attached to anything right...

My mother is looking at getting a saltwater tank for her home. She found someone who has a 75-gallon freshwater tank (empty) that he is willing to convert to salt for her. (this person has extensive saltwater experience and several very successful reef tanks). He wants to charge her $1500 for...
