I just noticed this worm coming out the other day ( now I've seen 2 of them ) and it almost looked like it was taking bites out of my torch coral. I'm not 100% sure if that is the case but I've definately seen one taking bits out of my live rock. Any idea what it is? From the pics I've seen...

I have a Royal Gramma that I bought 3 weeks ago and its belly is now white and it has a patch on one side that was white but has now darkened.. It also has been rubbing that side around the aquarium a bit. It has been eating fine although it doesn't like flake and seems active enough. It's...

I'm in the process of setting my QT back up after losing my new gramma in it and I'm wondering if adding a bunch of macros from my main tank would help suck up ammonia and make it less stressful for the fish? I know in fw tanks that the plants take up the ammonia before the bacteria but does...

Well I lost my first fish :( I set up a QT tank (10gal) about a week ago. Then the day before I bought the fish, I changed out about 25% of the water with water from the main tank and filled up an AC200 with bioballs that had been in the main tank for 6 months. This seemed like a pretty...

A little while ago I noticed that all of my spaghetti worms disappeared. There used to be about 10 or so in there and now I can't find a single one. I thought it was my recently added pistol that did it but then last week I cleaned out my canister filter and found a spaghetti worm in there...

I have a pair of juvinille TR false percs that I've had for about 3 months now. About a month ago I added a cleaner shrimp into the mix but the TR clowns don't seem to know what the shrimp is for:( Even now whenever the cleaner makes an attempt to clean them they just swim away. Even without...

I just got a pistol shrimp a couple of weeks ago...very cool animal to watch. Its quite the little sand moving machine. The one "problem" I'm having is that it steals every single empty shell I dump in and uses them to build its Fortress of Solitude. Its using them all the way down inside...

I see a lot of posts on DSB where people say that they must be done "properly" or else they can crash. I think I have it right but wanted to verify that this is what you would consider a proper DSB. I have a 2.5 month old 25Gal setup with about 45# LR about 3.5" of aragonite seeded with LS and...

Woke up this morning and noticed this black area under the surface of the sand and was wondering if anyone knows what happened and what to do. Everything else in the tank is doing great except this small colony of what I think are zoos that didn't open up today. Tank is about 2 months old...

Yesterday I noticed two instances where a large blue leg hermit appeared to be attacking another smaller hermit but instead I now think that they were protecting the newly molted hermits. In the morning I noticed a large hermit holding onto another's shell while hiding under a rock. It just...

I'm having problems with either getting all the salt disolve or with something precipitating out of my water when mixing sw, not sure which. I'm using IO salt with RO water from a commercial water company. I'm only mixing 3 gal at a time but I've always got white "stuff" left at the bottom...

I was wondering if there are any general rules to tell you if a crab will cause problems in a reef tank? Like the claws or some behaviour. I caught this one last night cause he looked pretty mean. TIA edit: you can't tell from the pic but it's bigger than a quarter.

Does anyone know what this is and if it will be taking over the tank? I can only guess that it is a sponge but I have no idea. At first I thought it was dead but I noticed yesterday that it started growing over a small community of polyps. Thanks for any help, Ron.

I just bought a jar of cyclop-eeze flakes from my LFS and when I opened it up I noticed that they are kinda greasy and soft. I'm used to FW fish with really crunchy flakes so is this normal? I'm guessing that its just the fats in the food that make it like that but want to be sure. Thanks, Ron.

To further enjoy my new-found addiction I decided to see what kind of night life I could find in my tank. I found these two and wanted opinions on them. The first one scares kinda freaks me out. I think its a crab? I'm using my nightshot video camera to try and see if he'll come out more...

I don't know how else to describe this thing. Wondering if anyone knows what it is. Same color as the coraline algae.

I just wanted to see what you think I should be doing next with my new tank. I have the following: 25Gal tank 2-3" aragonite seeded with grunge from lfs 12 lbs base rock 16 lbs LR (mixture of indo and fiji) 5 blue leg hermits 5 astria snails I plan to add over the next 1/2 year: more cleaners...

I just got my first ever load of lr and found something on it that looks to me ( from looking at the hitchiker faq ) like aiptasiidae. What do you think. Also this is my first attempt at posting a pic so my appologies if this doesn't work.

I just picked up some base "reef rock" from my lfs and wanted to see if there is anything I should do before adding it to my tank? Thanks.

I finally filled my 1st sw tank and added the aragonite playsand last night. This morning I noticed a few specs of what looks like rust in the sand against the glass. How big of a deal is this? Has anyone else ever noticed this in their tanks? At first I panicked thinking I'm doomed but now...

I'm thinking of getting a yellow goby and pistol shrimp since their interaction seems really interresting. I was wondering though if there would be any problems with a cleaner shrimp as well. If this would cause problems then which shrimp do you think provides the most benefit for a tank...

Does anyone know anywhere in Canada (specifically I'm in Ottawa) to get dry base rock and aragonite? I tried the HomeDepot play sand but it failed the vinaiger test. I could order the base rock on-line from the states but I think after shipping etc it will likely cost as much as the lr from my...

I'm starting out a new 25G FOWLR tank which will likely end up as a reef ( this is quite an addiction and I don't even own anything yet!) My question is on how much light I need for the 2 setups. For the FOWLR I've read a bunch of times that the basic NO lighting will do but I want to make...

I'm just starting off my 1st sw tank and just want to make sure I have this right so I don't waste $$ converting live rock into dead rock or killing fish. Here is what I'm planning on doing: Set up the tank with salt water and argonite. Order my LR and LS from lr.com Once it arrives add it all...

Does anyone have any experience or thoughts on this lighting system? http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&category=46314&item=4313419059&rd=1 TIA -Ron
