What is this? It looks like a white slug about an inch and a half long with white blooming flowers on top of it....any ideas? Good or bad thing??? Thanks! Sorry the pic is a little blurry.

Does anyone have some idea for our 75 gallon reef tank? We have a megaflow 3 sump below the aquarium in which we have removed the bioballs, but have a filter that catches the "stuff" above where the bioballs go. The door to open and shut the area to replace the filters is not water tight and...

My pink birdsnest coral just arrivved 4 days late - got lost overnight somehow. It is completely white. Does this mean it is dead? That's what I'm thinking.....But wondered if I dip it in iodine and then put under halides if the color could come back? Thanks,

Hi - We have a 75 gallon reef with a Devils Hand Brown leather coral near the top. We just changed 1 of our 2 metal halides (150 w) from a 10k to a 14k. The light was about a year old. Our devils hand has turned completely green in a couple days. No it is not algae. Did we burn it or will...

What is this big bubble thing in the middle of my coral? It just keeps growing and growing. At first I hoped it was a pearl but it it covered in algae. I don't know enough about the coral to figure this out so I will attach a pic and see if any of you know....THanks!!

While cleaning our tank our mushroom leather accidentally got his head in the way of our vacuum siphon thing. He's huge - about 12" high and now is completely laying on his side with a damaged top area. Is there hope he can come back? His stalk is bent over completely and it is probably 6" in...

Hi - we have a 75 gallon reef tank with live rock, sand, inverts, corals, sump with mangroves, etc. and a few fish. All peramiters are good- but we just got a new Aqua C urchin skimmer and it seems too clean (the skimmer) It foams and bubbles incredibly well but not much "gunk" is coming into...

Just replaced old skimmer 3 days ago with a aquac urchin skimmer. It is producing tons of bubbles and foam in the skimmer but none of the bubble are turning to "gunk". They are just beautiful white bubbles and foam. What am I doing wrong? It should have kicked in by now ( making gunk!) ANy...

Help - I just got a new clam and it's so frustrating..it starts to open and then a fish swims over it and it shuts and stays shut. It fell a couple times (uh -oh) off the rock ledge so just moved it to a stable spot but is it going to die? It still barely opens...we have a beautiful 75 gallon...

Ok - I'm so glad we didn't go anywhere this holiday weekend. We got a diamond goby (sand sifting kind) to clean up our sandbed. We have a 75 gallon reef with a sump growing mangroves in it....all has been fine but somehow the goby stirred up so much sand, it clogged our filter in the sump and...

Any ideas on best skimmer for a 75 gallon reef tank - it has to fit inside our 29 gallon sump. Our old one is just getting old and corroded! Thanks, Kathy

HELP - my poor goby is skinny as a rail...how can I get food to him? He keeps sifting the sand but looks awful....I've had him for 1 1/2 years. Any ideas??

Well what do you think? We love our fish tank - established 2 years - mostly corals....these pics have to be sooo small so hope it shows up.

Help - I have a spot (about 1")on a large brain coral ( puffy kind) that is rotting. Would an iodine dip help or is there anything I can do? Thanks for any help you can give me,

Hi - need help here. We added some live rock rinsed in freshwater from the LFS last week. Also Cheato, twigs, and a few new corals. We have a 75 gallon reef established for 2 years. All of a sudden our trates spiked up to 50-60 ( have been 20-40 max) this week. We lost a yellow leather. We...

Hi - we moved some things in our aquarium yesterday and added more live rock, corals...the anemone is basically in the same place but our cinnamon clown ( who has lived in this anemone for 2 years) isn't going into the anemone. She's hiding some of the time but won't lay in the anemone. Why...

Which is more likely to eat clams...mine seems to have someone munching on it..we have a couple brittle starfish and a coral banded shrimp that seem the most likely culprits to me. The mantle of my clam has little holes in it and the brittle hangs near it a lot. Any ideas?

Hi - We have a 75 gallon reef and it has a lot of coralline algae which is good - but there is some green algae on the glass that we cannot get off. It's like it is permanantly engraved into the glass. We use the magnets to clean it but they don't touch this stuff. Any ideas? Thanks,

Our water temp accidentally got down to 70 degrees. Could that be killing our corals? We lost a leather and I had to pull that off a rock it was attached to..and a couple other corals ( mostly leathers) look a bit bad. Our mushroom coral has retracted all its tentacles. It's 77 degrees now...

Does anyone know if this is something alive? What is it? I feel rather dumb but can't figure out if it is alive or not. It is stuck to my glass - in two spots. Thanks
