Noticed my fox face is breathing heavy and his gills are a bit bigger than usual but is color is fine. I saw him eating earlier off of the nori but haven’t seen him eat since even after adding food. He does have a spot of ick on him (he’s survived it before and it’s in the tank) I have a qt tank...

It's been growing on one of my rocks and on my crushed coral substrate. It looks like bubble algae although I'm not 100% sure it is. If anyone can ID this it would be appreciated.

Hi all, just recently found flatworms in my large frogspawn colony. Dipped it and about 7-8 small flatworms popped off. Inspected after it was back into the tank and nothing. I wake up this morning to check and now I see them on my green octospawn. Was curious how others approached this fix and...

Did my Nassarius snails kill my cleaner shrimp??? I just noticed them all on the shrimp today. He was fine earlier. I couldn’t get them off him. What should I do? Did I do something wrong with him? I thought they only eat dead things so maybe he died and they got to him right away?

I’m moving house and am looking to upgrade to a much larger tank. I want the tank in my bedroom, which is on the second floor. In terms of dimensions, the IM 50G Lagoon is perfect. I calculated the weight to be circa 780lbs (stand, tank, water, sand + rock). I plan to place the tank in a corner...

My plan is to get a 30-gallon reef started again. Here is the tank I'm thinking of. I wanted something more like 40 gallons that was a long tank that's rimless with low iron glass. I don't plan to have a sump, instead I wanted to have a canister filter with protein skimmer. I wanted to have it...

I noticed this morning my clownfish had puffy eyes they almost look swollen and white. I've tried taking a picture any idea on how to help her out?

Hi all I’ve noticed the past 2 days my clown has been acting strange sitting on the sand bed for long periods of time he’s eating fine and will swim actively I’ve read on a thread that behaviour like this can happen eventually leading to death and not knowing the cause all parameters are fine...

I ordered a bottle of Prime from a pretty big lfs/pet store and when I received the package i found 2 bottles in smaller size to make up for the 1 bottle i ordered. Either they ran out of the size I ordered or they gave me two smaller bottles cause they wanted to get rid of the older stock. Ok...

Originally thought this was some coralline but it took about a second to see it was growing over other algae, and taking over leading me to think it is bad. What do i do?

Have been having issues with what i think is dinos some of it goes away when lights are off and some dont. Should i buy a uv sterilizer what should i do. It does also get on my corals and rock not just sand bed Alk 8.6 Phos .01 Nitrate 8 Mag 1257 Calc 396

i got a bunch of corals from an online retailer a couple months ago and everything is happy and nice but this one $20 frag is causing me some trouble battling bubble algae and now what i think is Aptaisa. my fear is that it will contaminate the whole tank. is it worth trying to keep a small...

I have a nuvo 20 pro that sits on an aquarium stand and the leveling mat innovative marine sells with it. My display water level is off. I measured it and one side is 1 inch versus the other side being 1 inch and 1/4. I put a level to the tank and stand and all seems level. Is there something...

Hi Reefers, So I bought this colt coral few weeks ago, and I noticed that there is somewhat looking thingy next to it, so I though oh maybe that’s his kid or something (don’t judge me please ) But at night I realize it doesn’t scrunch in like the colt. Does anyone know what is that? should I...

I drilled my return line a little too high. I have a rimmed tank and the nut side of the bulkhead hits the trim so I can get it flush to the glass. Any ideas on how to remedy this?

Saw this spiky coralline algae on my frag, and it almost looks meaty. A bit clear and sticks out 2mm and 3-4mm on spikes. What is this? Should i remove it? I can get a beter photo later.

Hello everyone so I am soon going to purchase an RODI system for underneath my bathroom sink and before I get it I want to know where I should drill the hole for the drain line on the filter. I know putting it straight into the sink is an option but I’d rather have it look tidier. Some people...

Hey. I made an embarrassing mistake. When I put in my new heater for my reef tank, I somehow forgot to put the temperature reading gauge in the tank to monitor the temp and base the heat off the gauge. Therefore my heater was constantly heating up and my tank ended up at 96°F… Thank god I was...

Hi everyone, I have like 3 emerald crabs, and I noticed only one of them have this like algae or hairy stuff growing on its back. Does anyone know what is that? should I be concerned? should I remove him? On that note, would they eat seaweed? i’m concerned that they don’t have enough food and...

Found this crawling around in my sea urchin. It was flat and looked like a big flatworm. Dropped a bunch of eggs when I dipped the urchin in fresh water to knock it off. Sorry no better pictures.

A lot of the tissue has receded on this octospawn but there is still plenty there, about half. Easier to see when fully closed, it still somewhat opens, any dips or something i can do to recover it? I believe it was a bacterial infection no signs of brown jelly though. Thanks for...

Got this rock last week and I'm new in reef tanks, I don't know if this is too much or not.

Hi guys, i have moved my elegance coral on the of a rock and added one more light to my aquarium but it didnt like the water movement there(too much flow i guess) It wasnt looking healthy and then i placed it on the sand in the corner of my aquarium but here are the photos of it. What can...
