Hey! Tank has been cycled for 6 months, and was doing great. Had a gsp frag on the sand that was showing great growth, PE, and everything else. Then, one day after a 20% water change the polyps never come out again. It's been 2 days with them not coming out, is it dead? What could have happened...

Before I start, I would like to say I kind of hate using the word emergency here but it is time sensitive and blackout as in controlled, not a power outtage In my tank I have a very big Dino outbreak. I did a massive clean last night of siphoning the sand and cleaning off the rocks and glass...

Hi, I recently ordered a green bubble tip anenome from the divers den. Upon arrival it looks pretty sad. The mouth is wide open with white coming out of it? I am new to saltwater and this is my first anenome! I've had my tank for about 8 months and it has just been fish and live rock...

I couldnt find a clear answer. My tank is riddled with dinos and I'm currently working on removing them. Can dinos cause fish to eat less, swim less, and overall look lethargic? I took my clowns out to bring to my lfs, they offer free qt and hospital tanks so they are currently working on my...

Hello! My 46 gallon bowfront tank is almost finished cycling. I am hoping to add a clownfish or coral in the next couple of weeks. However before I do that I would like to fix the lighting on my tank. I have a light: However my tank has a rim and the lip of the rim is connected to the center...

Welp, I had a feeling this was going to happen but this is the situation I’ve gotten myself into. I found myself being extremely inconsistent with dosing Red Sea’s AB+ amino acid and looked for something that could be a more automated solution. I settled on Aquaforests amino acid they offer...

Hey everyone. So I bought 3 used AI Prime 16HD and they've been deleted from previous owners accounts. I plug them in and they're flashing green and blue which should be ready to connect. The problem I'm running into is they're not showing up when I try to add them from the app. I've tried 2...

I have 4 cromis and a few other fish and I need help identifying this outbreak. All the fish are fine except these dang cromis. One got very bad very quickly I think it go hit by a shrimp bullet or cleaner. But the other one has weird markings on it and it’s got no red and doesn’t look like...

4 green cromis 1 died but that’s nothing I’ve ever seen before. The other ones have weird markings on them that the first did not. The clowns goby’s and tangs are fine. Just These guys. I feel bad cause I can’t stop whatever it is from progressing if I can’t find out what it is. I’m feeding low...

I’ve had this 30 gal tank for a 2 months now, made sure to cycle it before. The sand gets dirty with red algee/bacteria alot, and so do the rocks. I do water changes every 1.5 weeks and frequently clean the algee of the walls of the tank. I was wondering if this was normal and if it will go away...

Please help. Does anyone know what this could be on my little clown? It started off as a red bump under his mouth, but has turned white and he now seems to be bothered by it and keeps his mouth open all the time. Tank is relatively new (2 months) and this guy seems to be having issues. He is...

I purchased a hanna nitrate checker and phosphate ulr checker. I wanted this because I'm currently fighting amphidinium dinos. My tank is roughly 4 months old, no Coral, 3 total fish with a bit of clean up crew. Nothing but rock and sand. No scrubbers or gfos to remove anything, no fuge. Even...

I’ve had this blue hippo for about 6 days now. He rarely eats and sometimes swims around. Now all of a sudden he is sitting by this heater at the top of the tank the whole time or sometimes he sits in the same corner and just sits there. What should I do please help lol?!

Hello, all! I got this gorgeous Trachy on Thursday of last week and I'm just not sure if it's happy or not... It came in perfect and puffy, put it in my tank (acclimated it first of course) then the next day started getting smaller and less puffy... I know they can deflate at night, but tbh it...

I just had to remove a ton of rock to get out a very aggressive fish. But now my clowns are acting really weird. Doesn't seem to be any parasite issue but they aren't eating which I assume is from the stress as they ate happily the day before I removed the aggressive fish. It's been a 16 hours...
