please help identify

I’m always smearing something new and well I have no clue what they are because I’ve only been an aquarium mother since Feb. Can anyone identify what the heck this thing is on the glass? Should I leave it in there? Take it out?

Hi you guys, so I have a 25 gallon tank, and everything is kinda new meaning it’s like 6 months in. So kinda still new. And everything is great except my sand… which is kinda like a light brown. With a tint of orange… if anyone can help me I would greatly appreciate it. I will add a picture and...

Long story short, bought a garage system growout because he was "moving", truth be told he had AEFW. Time I found out I lost boxes of acro colonies fighting them. Now 2 years later, the SPS and I are both on the rebound but sad I couldn't figure out this out sooner. Now I'm pretty savvy on...

Hi I'm new to corals I got this from Petco and I know it's a zoanthid but I have no idea what kind. I took the picture in white light so you could see it better. The coral under blue light has a slight orange tint. (I never use full white light on corals lol) I've done a lot of research and...

Can anyone tell me what coral this is ? Where to put it up high or low what kind of lighting bright or not so much ? Where it would be happiest in heavy water flow light water flow or no water flow ? Does it go on the sand or middle tank or up high in tank . In light it has pink stalks and green...

I found this in my aquarium i while ago I was told it is a porcelain but if so what type? Doesn’t look like an I have ever seen before it’s an almost brown color with two front claws but also the feathers that it uses to filter feed. I have a much better photo and or video I think that I will...

This hammer has been fine for months but is now retracting and looking worse and worse. I couldn't tell if this is something under it's skin eating it alive or it's just it's insides showing while it's dying . I tried to take pictures and videos. Thanks

I have these things all over my tank. I don't know what they are or from what frag they may have came in on. They seem to be eating my pods which I'm not too happy about because there's so many and I just bought. They do seem to grow everywhere even on coral in one case for sure. I'd love to...

Can someone please help me identify what these are never seen them before. Thanks in advance!!

Hi I got frag but I don't know what is it. Thanks

240g FO tank. 10 years stable. Newest 2 fish added 1 year ago. Tank: 12 common clowns, 6-line wrasse, Bicolor dwarf angel, sailfin Tang... Several months ago these "growths" appeared. Grow to 2-1/2" high, attached to shells and dead-coral-rock. Spreading slowly, starting as gelatinous-looking...

Can someone help indentify the item I circled in yellow? It has grown from nothing to this within about 10 days. It is super hard like a shell and I cannot get if off the rock with normal tweezers. I would have to use more force I think. (Don't want to bother it further until I know if it is...

Hello all. I got this blasto frag today and there are ***** worms crawling on it. I did a freshwater dip for 10 seconds while shaking the frag and then right back into saltwater where I scrubbed the frag plug with a tooth brush. I don’t have coral RX dip right now so this was the best I could...
