we have 2 hitchhiker crabs in our tank that we love to look at after dark. Theyre always out and about cleaning the rocks.
last night i was watching them and suddenly out of a hole near the larger crab there was this little electric blue flash in the shape of an upside down horseshoe. the crabs quickly hitailed it out of the area. i continued to look for it later that night but didnt see it again :eek:

are there phosphorescent(sp) creatures that live in live rock?
was i seeing things last night?
do you think it was good or bad?

any help would be appreciated.

if i hadnt seen it with my own eyes i would have thought i was up too late and seeing things, but the way my crabs just took off, it was definately something in the rock!

i vote for electric flame scallops. sounds exaclty like what you described. specially the color and shape of the spark. could be a baby.

where is your LR from? back when caribean LR was the norm, i used to get all kinds of phosphorescent worms. they would come out at night and flash. they would flash again a minute or two later. they were very difficult to see. the secound any light got near them they would duck into their holes in the LR. i have not seen any of them with all of my Figi LR.

ours is all Fiji rock,

whatever it was its keeping a low profile, i couldnt find it last night, i did however find that my hitchhiker crab pop is actually closer to 4 (2 biggies, 1 med, 1 small) im sure there are more too.

i hope these guys are good crabs, they are bigger than my hermit and my odd emerald.
