These guys like to hide until I feed the fish. Then they come out and roam all over the place in the aquarium.

If you have a saltwater aquarium with snails, you will probably know at this point that certain snails end up upside down from time to time. Can they flip themselves back upright?
During the course of having the 75 gallon tank I’ve now had 2 blue knuckle hermit crabs. The first one lived for just over 2 and half years.
This thing looks like it’s going to jump at you like a facehugger from Alien. It’s actually just a harmless crab, and I’ve even seen some videos of these in aquariums, but it is a weird animal.
A neat close up photo of a Picasso Triggerfish. This fish can grow up to nine or ten inches in length, and would probably be best suited for aquariums larger than 75 gallons.
If you watch this, you’ll understand why you want to keep your hands out of the tank if you have a mantis shrimp, listen for the knocking sounds while it attacks and eats!
What makes this video so interesting, or maybe not, is the fact that the snail is still moving really slow, even in time lapse.
If you are leary about adding an emerald crab to your tank due to safety of smaller fish, this video might give you a good idea why you are not too far off base.
Fish are usually jumpy critters, but when they want to be cleaned up by a cleaner shrimp, they will sit tight and let the shrimp do it’s work.
Some creatures eat bristle worms, just in case you need to get rid of them for any reason. I used to have some small bristle worms in my aquarium, like shown in this video.
