Trochus snail eggs or sperm? It’s been doing this for 20 minutes.

Can anyone tell me what this worm is? There are a few on this frag I ordered. Wondering to keep or kill.

Hey everyone. Is that aiptasia growing at the base of my Acan?

Hi Everyone. I feel like I have an Amphipod outbreak. They’re literally everywhere and there are some really large ones. I feel like eventually they’re going to run out of food because of their population. Does anyone have any recommendations on what to do? I feel like they need to be some fishes prey, but don’t want to wipe them out. I want balance, not extermination. Thanks in advance for any advice. I’d love to hear if someone has a good story about this topic.

Had a question for anyone that owns a court jester goby(Rainfords goby) or bi-color blenny. Do they do a good job eating hair algae? Which one is better at eating the algae if you’ve owned both? Thanks!

This is my first coral in my tank. I saw it at Petco and it looked sad, with maybe only 10 polyp arms out. I felt like I had to save it, so I added it to my tank probably earlier than I should have. However, it looks like it’s doing great. All polyps are always out and it already closed up for 2 days and shed its skin. I was wondering if any of you toadstool pros out there could give some advice. Does the flow look ok? Idk what par it’s getting, but should I move it up higher on a rock to get more light? Do you feed them anything specific? Also, can anyone tell me what kind it is? The end of the polyps look bright green with blue lights. Thanks in advance.
