Balix Posted May 17, 2016 Share Posted May 17, 2016 Don't know if this is friend or foe. I went through but no luck http://www.lionfishlair.com/hitchhiker.shtml The video is a bit blurry due to you tube compression but between 12 to 20 second of the vid is the best I could capture. Link to comment
LadyBryozoa Posted May 17, 2016 Share Posted May 17, 2016 Looks like an amphipod to me - harmless and free food if you've got any fish! Link to comment
SaltwaterShoup Posted May 17, 2016 Share Posted May 17, 2016 Nothing to be worried about IMO Link to comment
Balix Posted May 18, 2016 Author Share Posted May 18, 2016 I've got a clown, firefish and shrimp. The body is more like an isopod and NOT curved up like most amphipods. I recently introduced a colony of frogspawn from a tank where all the fish died but ran corals only the past 2 months (told me this after paying and bagging it up). Link to comment
LadyBryozoa Posted May 18, 2016 Share Posted May 18, 2016 The 2 primary differences between amphipods and isopods: 1) amphipods are laterally compressed (sides are flat - is this what you mean by "curved up"?) while isopods are dorsoventrally compressed (flat on top and bottom) and, most importantly, 2) amphipods have gnathopods (legs that end in a claw) in addition to thoracic (pereopods) and abdominal legs (pleopods) - also, all pairs of legs may look different (that's where the name amphipod comes from = "many feet") - while isopods have only pereopods and pleopods and legs in those two groups all look the same (isopod = "same feet"). The degree of "flatness" is extremely variable in the amphipods as well. The back end of this bug still looks curved underneath the body a bit (an amphipod thing) and just from the way it moves I would still guess amphipod - isopods tend to have slower, smoother movements (like a pill bug) while amphipods move around somewhat "jerkily" (is that a word?) Hope this helps Link to comment
