cucumber

I found this the other day and then it disappeared. I didn't see it anymore! Could it be a baby cucumber? It reminds me of hot dogs, and I don't have that kind of cucumber

Hi All, I am thinking of adding a sea cucumber, the Holothuria Hilla kind, to my 50g tank. Tank is half a year old and when I first ordered the CUC kit, I didn't want to include a cucumber that according to internet is wrongly considered as a nuke bomb. I read that they are very efficient in...

Hi all, This was sold to me as a “mini” black cucumber; the mouth seems strange though. Anyone know what this is, and if it’s reef safe? Main goal is to turn over my sand. Almost looks like more like a worm than a cucumber. I’m holding releasing it before I’ve got a firm ID. Thanks, Adam

I’m looking into sea cucumbers, the pink spiney and black and pink cucumbers. The issue is some websites say their care level is easy and others say expert only, so which is true? Anyone have either variety and have any insight?

I've been asked if I want a yellow dwarf sea cucumber, from what I've read people say that cucumbers can release toxins into a tank if insured or killed. Has anyone had this happen. I've also been told that the yellow dwarf cannot release toxins which seems abit odd but might be possible...

Hi all, So I found this thing slowly crawling along the waterline tonight... It's about an inch long, but stretches out a little longer and shrinks back a little smaller. It looks like it has some little feelers/antennae on the front. I for sure did not bring it into the tank at that size...

Hi guys, I just noticed this little creature appeared in my tank! It's probably a hitchiker ( i didn't add anything in my tank for over 2 months though?) but anyways. I would like to know what is it? I think it looks like a sea slug? Or a snail? I have no idea so i'm uploading this video and...

Hey everyone so this is I think my first post. So I was contemplating getting a tiger tail sea cucumber and was curious about whether it and my already present pistol shrimp would get along. Would the pistol shrimp cause it to get stressed enough to release toxins? I have a 180 gallon tank and...
