nub question. I have a 10 gallon nano right now (all softies, snail, shrimps, anemone) that I'm planning to move to a 30 gallon long with 35 gallon sump and skimmer then add some fish. Can I simply move the rocks and corals to the 30 gallon, and add 20 gallons of water to the mix and slowly...

I bought this coral two weeks ago. I haven't seen it come out. I have tried to feed it but I haven't seen it eat at all. Is it dead? How long does it take before they come out?

I moved one frag of my zoas and noticed that it's got green algae on the polyps. How do I get them off?

I just wonder if my zoas got foot fungus coz.... I noticed some of the new frags I bought started developing fuzzy stuff on them 5 days after being brought into my tank. I did fresh water dip, and the white stuff washed off. But this one frag, OMG, it smells PUTRID. I have kept it in a salt...

I had been mucking around in my tank this weekend you can tell. I also bought some corals. And one frag was too big so I broke it in half, and in the rock was an orange colored worm. It had no bristles, and I tried to pull it out with a tweezer but it slinked out of the tweezer and into the...

I found one of these little transparent fan-like things (left and right ) on my rocks two weeks ago. And then it's become three or four. The one in the middle earlier in the week. Just one. now there's five of them in the same area. when they are open they are about a small button size. The...

I was moving the rock the acans were on around the tank as I had bought more corals. There was turbulence in the tank water, a bit more than with powerheads. And I noticed my acans had these white stringy stuff coming out from the edges. What's that stuff? Why do they do that?

Hi, I have been trying to do research on this coral since acquiring one recently. There are a lot of conflicting information on this coral. Lighting - some say low, some say high. How can this be?! Water quality - I have read that for some, it should be clean, while others have said they like...

I have this "hitch hiker" coral in my nano tank. Someone mentioned that this could be a sponge. I couldn't find any sponge coral photos online that looks like this.

Freakin hermit crabs and crabs and bigger snails are crawling over and knocking over the plugs in my sandbed!!! every morning I find them tossed on the sides. I do NOT like putting my hands in the tank frequently. A tank less meddled with is better than a tank meddled with often. Should I get...

Someone asked if I had any bioload in my nano and I said anemone. They thought I still need fish in there. This is a mature 10 gallon nano. It did have fish before, now just the anemone. Thoughts?

I have a bubble tip anemone. It used to hide when the lights go dark. Last night, it stayed OPEN when the lights were off. Then this morning, I saw its mouth open for a while. When the lights came on, it closed its mouth. It and the tank's been moved recently, and I am concerned it might be...

Hi, I bought this from a guy today. He said it's nuclear green zoa. I'm not sure that it is. It isn't bright like a nuclear green. It isn't as big either. when fully open its a bit smaller than a penny. I didn't mind getting it, just want to know what it is specifically.

I recently got a mature nano 10 gallon tank from an enthusiast. I noticed that in my apartment the water (open top, good flow) top up is coming to about 6-7 liters a week or about 1.6-1.8 gallons. That's more than the 10% water change per week that's recommended. If I'm topping that much, how...

Hello peeps, I'm from Toronto. I've been keeping fresh water tanks for 20+years, have lived and travelled in tropical southeast asia biotopes (quite recently too). But I am a nub in salt water, having just got a nano tank. I found a thread on this site through google and found the community to...
