R.I.P Mr. Mantis Shrimp


Well there has been a lot of changes in the system over the past couple of days. I’ve been trying to move everything out of the temporary tanks and into its permanent home. I guess that was a little too much change for the mantis shrimp. He’s been living in the refugium attached to the new system for a couple weeks now. He recently molted over a period of two or three days and in a matter of a couple hours after he was finished, he died. Not sure if it was too much action from the move or if he had a rough molt. We’ve had him for a little over three years but from what I read, they can potentially live for up to twenty years.

90 Gallon Refugium Update


Red Mushroom Corals

An update post of our 90 gallon refugium. I don’t see it very often with the lights on as it’s reverse lit (11:30 PM – 7:00 AM). I really like how big the mushrooms are when the lights (48″ Tek Light T5) are on. The mushrooms kind of cover up the mantis shrimp’s PVC cave system.

I was trying to get a good video of the mantis shrimp breaking into a snail for lunch but instead he was curious of what I was doing and tried to sneak up on me. ūüôā

Listen for it… Crack! Every time I hear this I go to make sure he’s not hitting the tank. Thankfully the 90 refugium is made out of half-inch glass.

Peacock Mantis Shrimp Update


Quick video of our Peacock Mantis Shrimp (Odontodactylus scyllarus) feeding. I’m really happy that he’s coming out more and wandering around the refugium. ¬†Hopefully he will start eating the baby peppermint shrimp.

90 Gallon Salwater Refugium Update


I recently pulled a bunch of algae out of the refuge and thought I would take a couple update photos. The peacock mantis shrimp is the only creature living in the refugium. He pretty much lives in a conch shell buried in the rocks on the right side of the tank. He often chops off pieces of SPS coral to build with, lol. Since the damselfish removal the bug population has exploded! I’m really happy to have the bugs/pods back!

Peacock Mantis Shrimp (Odontodactylus scyllarus) Feeding


Our Peacock Mantis Shrimp (Odontodactylus scyllarus) has been more readily coming out to feed lately.¬† When he darts out to eat his piece of shrimp I can see how much he’s grown! With the removal of the damselfish from the tank, maybe he will be out exploring more.

Mantis Shrimp (Gonodactylaceus ternatensis)


Here are a couple pictures and a video of our Mantis Shrimp (¬†Gonodactylaceus ternatensis). We’ve had him for a little over a year now and he lives in our 90 gallon refugium.¬† He has molted twice within the past three months and has gotten quite a bit bigger! Right now he’s probably 5 inches long but noticeably more girthy than before. He “shucks” his shell into the tank and hides for about a week until his new coat of armor has hardened. This morning I found one of his “smashers” sitting outside of his conch shell. The right side of the smasher (below) it the hammer part he uses to open up crustaceans and break things.

He’s a video of when we first got the mantis shrimp:

About six months ago we put an octopus in our refugium which caused the mantis to reevaluate his current living arrangements which gave me the chance to take the picture below. The octopus soon laid eggs and perished. Since our refuge runs on a reverse light cycle, I don’t get to see the mantis shrimp as often as I would like but he has a damsel in the tank to keep him company.
