eggs

My tank is pest free (as far as I am aware, quarantine frags fish etc etc). I have these egg looking things on one of my rocks and wondered if anyone has an ID? There are often snails there and a sea urchin likes to hang out there too. They are around 2mm in diameter and don’t look like normal...

hey guys found some white spots all over my rocks snail shells empty shells pretty much everywhere My first idea was to poke it and rip them open looks like a dust comes out i suspect snail eggs or something looks like eggs that’s for sure isn’t calcium cause it’s only on the rocks and shells...

Blue throat trigger fish spawning!! When the eggs were released, the other fish went into a feeding frenzy! I've had them for 1 year and 9 months. They were not purchased as a pair. Actually, they had no interest in each other for about the 1st year.

Last night I was lucky enough to come home from work to catch my mini maxi's spawning. Feel free to ask any questions :) I can tell you, I do water changes about once every two months, I never test water parameters, and I use tap water... I know you are all probably cringing at the sound of...

Check this out! I returned home from my trip to the LFS tonight to find my now seemingly mated pair of clownfish laying their first ever fry!

I have a 180g saltwater tank. I bought it 6 weeks ago. It was already a 3 year established tank. So far everything survived the moved. As well as a few new editions. We have three clowns, 2 blue damsels, 2 black damsels, 2 white striped damsels, 1 yellow tang, 1 mandarin dragonet, 1 lawnmower...

Happy Thursday Soo I got some zoas that were getting eaten by this little Dude but I got him out. I am noticing more than just him. Please help me identify what I need to do. Thanks in advance
