Ok, I think they are zoo's that have not opened up yet but I don't have very good lights yet and won't until the end of the year. I just have about 90 to 100 watts of fluorescents on my tank for now, have like one 48" 40 watt and 4 15 watt . I have a few more zoo's that are a diffent kind that have already opened up but all of these are kinda in the shade not right in the light and dont want to move all my rock just for them. Do you think they will make it? kinda cool they all where hitch hikers.:joy:
