Hello, I am conducting research on megalopae (larval) stages and I have come across a few that I do not have a species for. Two of these may be the same species, as they looked similar but one is darker. The third is white with that distinct strip so I am thinking maybe a rock crab? I have a...

This guy started out on a rock in refugium, when I went to move the rock into my DT, I popped him off and stuck him to the wall in refugium due to me thinking he was a baby snail. He was about a 4th of the size he is now. This thing has not moved an inch in three months now, but it’s still alive...

Hello, i have an unusual pet which is a Red Rock Crab (Cancer productus) and just aquatic crabs in general are very hard to find good information about other than cooking. I've had him for about 9 months now. I keep the water temperature and salinity matched to his natural home (Puget Sound)...

Hey, just looking on some opinions adding another cleaner shrimp to my 75G, I currently have a pretty massive skunk shrimp in the tank about 4" not including his whiskers, it's been in the tank for a bit over a year, the only saltwater stores around my area only sell smaller shrimp maybe about...

I’m having trouble figuring out what this thing is, a couple of them came on a clump of spaghetti algae I had purchased. I will post some pictures down below. Sometimes I will notice them swimming through the water column like a jelly fish when I shut off the pumps for couple minutes to feed my...

I've raised Land Hermit Crabs for a few years, and now I want to raise Marine Hermit Crabs. I have no intention to raise other animals in the aquarium, but should I? Would it hurt my Crabs if they're raised with only other Crabs of their species?
