Has anyone ever seen this on button polyps before? The parameters got out of hand for a couple weeks and there was a bit of a hair algea bloom. I've just gotten that cleared up and also the lights were old so I just replaced the bulbs yesterday. Could one of those have been the problem or is it...

Had this green bta for 2 or 3 weeks now. Has stayed in the same place I put it and has been eating and looking healthy. I just found one of it's bubbles in the intake of a pump and pulled it out. It's still inflated. Any reason it would drop a bubble? The pics were taken 5 minutes ago, just...

I bought 2 frags of zoas about a month ago and a few days later pulled 2 nudibranch's out of my tank. After doing a fresh water dip on the frags one of them still quickly disapeared. I did a second fresh water dip when there were 2 heads left on it but they were gone in a day or 2. The second...

I just got a green bubble tip anemone tonight and it's been in the tank for a bout 2 hours. It was looking good until my pepermint shrimp just came up and started picking at the bubbles. This made it start to shrivle up and it didn't look like a good thing at all. Would the shrimp have been...

I got a few frags yesterday and just found this little nudibranch? in my tank on some hair algea. Is it good or bad? Could this also be the culprit who ate part of my sponge?

It looks like something ate part of one the sponges in my tank either last night or today. Looks like it ate mostly the inside and left just the outsides of it. What might do this?

I have a double t5 ho on my 28 gallon. I was thinking about replacing the actinic with another daylight bulb to get a little more growing power out of the light, and getting a blue led for the glowing look. Does this sound like a good idea or is there any problems with this? Thanks you.

My tank sits on my large computer desk and on the floor beside the desk is my laundry hamper. I had noticed my six line wrasse MIA last week but hadn't had time to watch the tank to see if he was just hiding. So I did a load of laundry that same day and when folding it on my bed found the head...

I have had an aglea problem since June. It started out with green hair algea growing in a couple places and then red slime algea started growing everywhere. It's even been growing over some of my polyps and they aren't doing so good anymore. I'm wondering if I need to replace my t5ho bulbs...

I got a pulsing xenia a few months ago now and it was fairly small and a lightish pink colour. I put it mid level in my tank with t5ho lighting and its become a darker more purple colour. Is this a bad thing? It's definately had a fair amount of growth since I got it. It's currently sitting on...

I recently noticed one of my snails with a bunch of those tiny spiral shelled snails around it's opening. I know they will eat the mantle of clams but do they do the same with snails? In the picture you can see the snails on the bottom and left side of the big snail, Turbo I think? The snail is...

I moved away for a couple months and had my brother taking care of my aquarium while I was gone. I came back every weekend to do any maintenance it needed and I noticed after the second week my female clown started getting a little aggresive towards me. I'm back home now and the clown has...

I have never owned a starfish before and I was at the lfs today to pick up a few pieces of live rock for a nano aquarium I have started in my temperary home away from home for a couple months. In the giant container the store has all it's Fiji live rock in, was a 3 or 4" red starfish. It's got...

I don't think this is the right topic for this thread but I didn't know where else to put it. I want to buy some live copepods from the lfs but I want to breed them so I will always have a supply of them. I heard something about putting some in a jar with tank water and a bit of filter floss...

I just got home from work today to see my sixline harrassing 1 of my green chromis'. The other 2 were out of sight. I've had the chromis' for a couple weeks now and have never seen my six line chase anything ever but now he goes after the chromis' like a shark. I didn't even think that six line...

I just got a Mandarin Goby about a week ago. I've got an algea scrubber as my only filter other than live rock and sand. When I first put her in the tank she was all over the rocks and eating something every 20 to 30 seconds. Today I noticed she was staring at the glass and would move back and...

Ive got a chalice (Watermellon Challice I think) and I was wondering where it should be in my tank. I've heard a lot about putting it on the bottom but I only have a double t5ho fixture on my tank. Kevin

Is having a surface skimmer necessary if I have good surface agitation?

I just changed the rockwork around in my tank and noticed that a lot of the sand bed had about an inch or so layer of sand that hardened almost like concrete. Is that a bad thing and what would have caused that? Thanks
