green glowing dots

[theorkinman]

hi.. im very new to this hobby.. i just got a 55 gallon tank about 2 weeks ago... i live in the virgin islands so i went out and got some fresh live rock for the tank...for the first time tonight, i noticed a small dot blink in the tank, so i turned out everything i could to pitch black and these things were going crazy... im sure somebody here knows what these things are.. and how can i keep them alive..also, how many sea urchins is too many to keep in a 55 gallon tank... i have two baby sargeant majors and some type of hogfish which is about 3.5 inches....

Welcome to AquariumAdvice.com

Typically it will be amphipods. They will do this in order to attract mates. I have seen it a few times myself and have been able to identify them. Might not be the case with your's but a fairly good possibility.

Cheers

I was gonna say, in the stuff I ordered in the amphipods I noticed some that where more green than clear
