Today I noticed that my Green Star Polyps were not opening like they should. It also looked as if parts of it were ill. I picked it up and moved it into better view, and there were small whitish patches on one side. They have a weird, hole-covered look to them and when touched with a skewer they...

Since I started my tank I have used a hang on back filter which came with the tank alongside my canister and refugium. It is pretty much backup at this point, and barely causes enough water flow to matter. I want to remove it and use something more affective, like a skimmer, but I'm worried that...

About a month ago, my dwarf angel went bananas in my tank and began picking at most corals, causing a good bit of stress for them. I quickly removed it from the tank, and now everything has opened back up except my zoas. They open about halfway at most, and aren't open for very long. Parameters...

Hello everyone. For the past several months I have been having a recurrent problem with my BTA. I purchased it about seven months ago, and it acclimated well to the tank with good tentacle extension, color, and little movement. It did great for about a month, until I introduced a pair of percula...

Yesterday, I received an online order of what I had been told were photosynthetic gorgonians. I had my doubts upon seeing them, and once I got them in the tank their white polyps have them away. They are positioned right below the outflow of my refugium, and the polyps have been extended since i...

Hello. Sixth months ago I purchased two clownfish from my LFS. They were sold as "nano ocellaris" clowns. They were under an inch long, but proportionate to any normal clown, so I figured they were just immature specimens. Sixth months later they are about an inch and a half each and seem to be...

Hello everyone. Today, a I received an online order in the mail. One of the items, which was labeled "purple sea whip", looks nothing like any purple sea whip I have seen. It has good polyp extension and is in high flow and mod. Lighting. It also ate when I tried spot feeding it. Any ideas what...

Today as my lights started to turn on, I noticed these weird stands of what look like some kind of egg on the glass. Any ideas what they are? Sent from my iPhone using Aquarium Advice

Hello everyone. This summer I will be assisting my parents in redoing their pond. It is pretty crappy right now and they want to fix it up. I am more knowledgable in the saltwater world and have little experience with ponds. Any advice on what kinds/brands of filtration to use? The pond is...

Several days ago, I purchased a rock which was mainly populated by orange ricordeas. The guy at the lfs pointed out a greenish growth also on the rock, however he did not charge me for it. Any ideas what it is? Sent from my iPhone using Aquarium Advice

I just got my first sps coral (tiny drag to see if my parameters are good enough) and have no clue what it is. Sent from my iPhone using Aquarium Advice

Hello, Recently, I lost many of my fish to an aggressive wrasse. The wrasse has been removed, but it killed my green mandarin that I had had for nearly a year. My question is, would I be able to house a green mandarin with a blue striped pipefish? I would like to replace my mandarin, but I also...

Hello. Around two weeks ago, I witnessed my six lined wrasse killing my mandarin goby. This was the only aggression I have wet seen from it, but since then small fin nips or marks on the skin of my ocellaris clowns have been common. Today I came home to te smaller of them dead, with its fins...

Hello. I am looking to add a bit more rock to my aqua scape so that I can fit more corals in my tank. I have heard that adding too much rock at one time can create a mini cycle due to dead material on it. Is there any type of rock that I could avoid this with, and if not, would boiling it first...

I got this about a month ago from a local frag swap. They said that it is photosynthetic, but I still feed it every once I a while just in case and it is growing nicely. Any ideas what type it is? Thanks. Feeshna

Hello aquarium advice. I just looked at my tank and noticed that one of my ricordea floridas is completely gone? It was on a frag mount, however it looked like it was starting to move about an hour ago. I checked all of the pump intakes to make sure it didn't get sucked up, but I can't find it...

Hello, I have had my 40 gal nano reef set up for about 8 months now and all of params have been stable. I am using strong lighting and having no health problems with fish or coral, and would like to try out an anemone. I have read that Condys, BTAs, and LTAs are the easiest, however I would...

About two months ago, my entire colony of green star polyps was wiped out by an urchin (not sure what kind but I no longer have it). Just a few days ago I noticed a single polyp still growing on the live rock. Is it possible that it could make a comeback? thanks.

Yesterday I purchased a fuzzy dwarf lion. At my lfs, they were feeding it ghost shrimp and guppies. I would like to wean him off of these foods and feed him something prepared, but how should I go about this? Any input will be helpful. Feeshna

Te other day I noticed that my bubble coral, which I have had for about tree weeks, was suddenly not looking so good. It has been closed mostly, no more tentacles at night, and a small brownish tuft has appeared at the tip of one of the skeletal ridges. Oddly enough, all of my other corals are...

I currently have a one bulb t8 fixture on my new reef tank. I plan on changing this once I am ready for corals, but are there any bulbs that would fit this fixture that could support soft corals? If not I will get another fixture but I would like to know whether or not I could use my current...

I read about these online. Are they any good? I don't have room for a real refugium but I do for these.

Yesterday I set up my first saltwater tank. I have about 10lbs of LR from a friend's system, 20lbs of dry coral rock, 3 mangrove propagules (also from a friends tank). About how long until my cycle will be far enough along to start adding some hardy fish?(damsels, salt mollies, etc) I heard from...
