Urchin may sting the cuttle, according to other posts. The cuttle has nowhere to hide from it, and they will eventually collide.
hmm... guess the urchin will be either traded in or transferred to another tank...

Also yay~! more mysis come in today, hopefully I can take pics of the cuttlefish hunting them.

Nope, no luck on that... i think he is eating them rather quickly, OR I havent seen any today at least and I introduced 100 on saturday.
Will be purchasing 200 this weekend, tho, hoping that'll help them get established. I am assuming in the mean time, that he is eating mostly amphipods in my tank, as I have tons or rather large ones.

Yeah mine seemed to prefer amphipods after the first week. Unfortunately catching them and putting them in the net breeder was tough.
Make sure you drip acclimate the mysis. They are probably sent to you at 1.015 ppm. Most will survive either way... just allways good practice.

yeah I can't imagine catching amphipods to put into the little breeder net... those buggers are fast!! Fortunately my tank is crawling with them. Ive been acclimating my mysis in the manner described by (I think it was) Thales somewhere else on the site (adding a cupful of tank water every (i forget how many) minutes.... tho its not a guide for mysis specifically I figure it works.

Just wanted to post a quick update, as today my cuttlefish is a month and 2 days old. Here's a photo I took earlier:




Should be getting another lot of mysis in this week. I attempted to feed him frozen mysis twice at this point, I am not exactly sure what to think of the results -- on the second mysis feeding, I thought I saw him grab one out of the current, but he just seemed to have dashed into it as opposed to using his "stretchy" "hunting" tentacles (for lack of better wording..). Do cuttles only hunt using those? Or could I have possibly witnessed it grab some frozen mysis then?

Anyway.. I believe his primary food source, other than the mysis I've been buying for him are these guys:


Theyre about 1/4inch long and all over the place. You literally cant stare at any point in the tank for more than a few seconds without seeing at least 3-4 of them scuttling around. As you can see I let some algae stay on the glass cause the 'pods seem to like it & makes them sitting ducks for the cuttlefish. . . . or at least I think so... haha


Took this photo a couple of days ago. I was worried he was getting sucked into the filter (he was perfectly fine, im just paranoid, heh). It still amazes me how well he can maneuver in the current despite his small size.


One last photo, I love how he changes color/shape!!

I would say you are ready for shore shrimp.... I just dumped mine in the tank with the cuttles and let them free feed... Once they got to shore shrimp they grew very quickly!

What kinda setup you have him in by the way? from the pictures is looks interesting. Also, if you get shore shrimp i would suggest getting 100... That should last him several months and I would think you could slowly ween him onto large frozen shrimp as they run out.

I currently keep him in a 30 gal biocube (29gal?) I put "stuff" on the filter intake because I was afraid he'd get sucked in after he hatched.

I am a little concerned as to wether or not he's big enough for shore shrimp.. I would say he is between 3/4-1 inch in length. I am going to try buying some small feeder shrimp at my lfs and see what happens over the weekend, then order either mysis or shore shrimp on monday...

Don't under estimate their small size. Cuttlefish can capture and kill prey larger than themselves. Generally you want to give them something no larger then their mantle, but a little larger or smaller wouldn't hurt as long as its not an agressive prey animal. You can also trick them into eating whole unpeeled frozen shrimp. I had my S, Pharoanis eating frozen prawns larger than themselves by making it "dance" in front ofthe with a clear acrylic rod.
